It can identify small or large tumors, multiple sclerosis (MS), encephalitis (brain inflammation), or meningitis (inflammation of the meninges that lie between the brain and the skull). Cancers (Basel). . Infections and eosinophilic granulomaInfections and eosinophilic granuloma are exceptional because they are benign lesions which can mimick a malignant bone tumor due to their aggressive biologic behavior. There are two patterns of periosteal reaction: a benign and an aggressive type. Age: most commonly seen in 10-25 years, but may occur in older patients. Click here for more examples of enchondromas. A bone island larger than 1 cm is referred to as a giant bone island (12). Skeletal Radiol. Gulati V, Chalian M, Yi J, Thakur U, Chhabra A. Sclerotic Bone Lesions Caused by Non-Infectious and Non-Neoplastic Diseases: A Review of the Imaging and Clinicopathologic Findings. This is consistent with the diagnosis of a reactive process like myositis ossificans. These are inert filled-in non-ossifying fibromas. Giant cell bone tumors are usually benign (not cancerous) but the malignant form can affect the legs, especially near the knees. On the right T2-WI with FS of same patient.. In this article we will discuss the differential diagnosis of sclerotic bone tumors and tumor-like lesions in more detail. Differentiating between a diaphyseal and a metaphyseal location is not always possible. Fundamentals of diagnostic radiology. Osteoblastic bone metastases are characterized by increased bone formation 2. Some prefer to divide patients into two age groups: 30 years. MR usually shows a large amount of reactive changes in bone and soft tissue. Osteoid matrix in osseus tumors like osteoid osteomas and osteosarcomas. When considering Pagets disease, it is extremely helpful to note whether there is associated bony enlargement. On CT sclerotic bone metastases typically present as hyperdense lesions, but display a lower density than bone islands 5. The bone scan is also helpful to look for additional sites of increased uptake that may not have been imaged, such as multiple nontraumatic rib, calvarial, or long bone lesions, which would strongly suggest the diagnosis of metastatic disease. FD is often purely lytic, but may have a groundglass appearance as the matrix calcifies. Purpose: To determine if sclerotic bone lesions evident at body computed tomography (CT) are of value as a diagnostic criterion of tuberous sclerosis complex (TSC) and in the differentiation of TSC with lymphangioleiomyomatosis (LAM) from sporadic LAM. Radiographically, GCTs are eccentrically located radiolucent lesions with well-defined lytic 1B margins and geographic bone destruction. However, a specific density range has not been specified for those terms 1. The image shows a calcified lesion in the proximal tibia without suspicious features. Click here for more examples of eosinophilic granuloma. Parosteal osteosarcoma is a sarcoma that has it's origin on the surface of the bone. Eosinophilic granuloma like osteomyelitis, can be a serious mimicker of malignancy (particularly Ewing sarcoma). by Clyde A. Helms Osteosarcoma (2) Cartilaginous tumors in particular chondrosarcoma may show endosteal scalloping, while a bone infarct does not. Generally, this just follows common sense some lesions should logically be expected to be focal, others multifocal, and yet others diffuse or systemic. 1 When the vertebral lesion has no benign features, especially in the older adult patient, metastatic disease is always a significant consideration. NOF, fibrous dysplasia, multifocal osteomyelitis, enchondromas, osteochondoma, leukemia and metastatic Ewing' s sarcoma. Here some typical examples of bone tumors in the foot: Fundamentals of Skeletal Radiology, second edition Mixed lytic/sclerotic lesion of right posterolateral 10 th rib, with extensive aggressive-appearing periostitis, as well as a multilobulated soft tissue component. Degenerative subchondral cyst: epiphyseal, Chondroid matrix in cartilaginous tumors like enchondromas and chondrosarcomsa. Multiple enchondromas and hemangiomas are seen in Maffucci's syndrome. Click here for more information about bone island. A high grade chondrosarcoma must be considered in the differential diagnosis. Interventional Radiology). There is no calcification and lesions may be expansile. {"url":"/signup-modal-props.json?lang=us"}, Knipe H, Yap J, Masters M, et al. This could very well be an enchondroma. Sclerotic bone lesions caused by non-infectious and non-neoplastic diseases: a review of the imaging and clinicopathologic findings Sclerotic bone lesions caused by non-infectious and non-neoplastic diseases: a review of the imaging and clinicopathologic findings Authors Scuba Certification; Private Scuba Lessons; Scuba Refresher for Certified Divers; Try Scuba Diving; Enriched Air Diver (Nitrox) Particularly chronic osteomyelitis may have a sclerotic appearance. Diffuse bony sclerosis (mnemonic). 1. A chondrosarcoma was diagnosed at biopsy. 2, The primary utility of the bone scan is that if there is no increased uptake, sclerotic metastatic disease is highly unlikely; therefore, the lesion can be considered most likely a bone island and follow-up radiographic imaging obtained. Osteosarcoma with interrupted periosteal rection and Codman's triangle proximally (red arrow). In this article we will discuss a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-22391. Many important signaling . Notice the resemblance to a juxtacortical mass in another patient (right), which was a biopsy proven parosteal osteosarcoma. {"url":"/signup-modal-props.json?lang=us"}, Gaillard F, Knipe H, Weerakkody Y, et al. The epiphysis, metaphysis and diaphysis may be involved. Here, we showed that sBT values are higher in patients presenting 496 with bone loss . When a reactive process is more likely based on history and imaging features, follow-up is sometimes still needed. In some cases however the osteolytic nidus can be visible on the radiograph (figure). Paget disease is a chronic disorder of unknown origin with increased breakdown of bone and formation of disorganized new bone. The sagittal T1WI and Gd-enhanced T1W-image with fatsat show a large tumor mass infiltrating a large portion of the distal femur and extending through the cortex into the soft tissues. Endosteal scalloping of the cortical bone can be seen in benign lesions like Fybrous dysplasia and low-grade chondrosarcoma. Physical examination and past medical history were normal and noncontributory respectively. Sclerotic or blastic bone metastases can arise from a number of different primary malignancies including prostate carcinoma (most common), breast carcinoma (may be mixed), transitional cell carcinoma (TCC), carcinoid, medulloblastoma, neuroblastoma, mucinous adenocarcinoma of the gastrointestinal tract (e.g., colon carcinoma, gastric carcinoma), 20 yo M w/ 5 cm lytic bone lesion in proximal tibia metaphysis, sharply demarcated w/ sclerotic rim. Causes include trauma, infection, autoimmune diseases, inflammatory diseases, spinal degeneration, congenital malformations, and benign or cancerous tumors. In aggressive periostitis the periosteum does not have time to consolidate. AJR 1995;164:573-580, Online teaching by the Musculoskeletal Radiology academic section of the University of Washington, by Theodore Miller March 2008 Radiology, 246, 662-674, by Laura M. Fayad, Satomi Kawamoto, Ihab R. Kamel, David A. Bluemke, John Eng, Frank J. Frassica and Elliot K. Fishman. Fibrous dysplasia, Enchondroma, NOF and SBC are common bone lesions.They will not present with a periosteal reaction unless there is a fracture.If no fracture is present, these bone tumors can be excluded. 5 Biopsy should be considered in atypical cases or in high-risk patients with primary malignancies associated with osteoblastic metastatic disease. Surrounded by a prominent zone of reactive sclerosis due to a periosteal and endosteal reaction, which may obscure the central nidus. Here a lesion located in the epi- and metaphysis of the proximal humerus. Radiology. Patients with sclerotic lesions due to metastasis often have a history of prior malignant disease. However, cancers that metastasize to bone are very common. The lesson here is that when we are dealing with a very common disorder, even its less common presentations will be seen commonly. Likewise patients with sclerotic lesions due to various drugs or minerals will tell you what they are taking if you ask them. Coronal T1W image shows lobulated margins and peripheral low SI due to the calcifications. Metastases are the most common malignant bone tumors. At the periphery of the infarct a zone of relative high signal intensity on T2WI may be found. Both imaging modalities achieved only a moderate correlation with DEXA. W. B. Saunders company 1995, by Mark J. Kransdorf and Donald E. Sweet Focal sclerotic bony lesions (mnemonic) Last revised by Daniel J Bell on 18 Feb 2019 Edit article Citation, DOI & article data A popular mnemonic to help remember causes of focal sclerotic bony lesions is: HOME LIFE Mnemonic H: healed non-ossifying fibroma (NOF) O: osteoma M: metastasis E: Ewing sarcoma L: lymphoma I: infection or infarct After an injury, different types of fluid can build up in a bone. Fibrous dysplasia and eosinophilic granuloma more commonly present as osteolytic lesions, but they can be sclerotic. Notice the numerous predominantly osteoblastic metastases. Should be included in the differential diagnosis of young patient with multiple lucent lesions (Langerhans cell histiocytosis). General Considerations Therefore, MRI and bone scan were performed. Patients usually have sclerotic bone lesions before and lytic bone lesions after puberty. A mean CT attenuation threshold of 885 HU and a maximum attenuation threshold of 1060 HU has been found supportive in the differentiation of untreated osteoblastic and bone island in one study 7, but the exclusive use of attenuation values for the assessment of sclerotic bone lesions has been discouraged 8. Brant WE, Helms CA. 5. ImageBenign periosteal reaction in an osteoid osteoma.Large arrow indicates solid periosteal reaction.Small arrow indicates nidus. The differential for multifocal lesions happens to be identical to that for focal lesions. Strahlenther Onkol. Radiological atlas of bone tumours of the Netherlands Committee on Bone Tumors Therefore, knowing the homogeneously sclerotic bone lesions can be useful, such as enostosis (bone island) (), osteoma (), and callus or bone graft.The plain radiography and CT images of enostosis consist of a circular or oblong area of dense bone with an irregular and speculated margin, which have been . It is most commonly located in the outer table of the neurocranium or in a paranasal sinus. This could be an osteoblastic metastasis or an osteolytic metastasis that responded to chemotherapy. Click here for more detailed information about NOF. I think that the best way is to start with a good differential diagnosis for sclerotic bones. The differential diagnosis of solitary sclerotic bone lesions can be narrowed down according to the following factors 1-3: cartilaginous matrix (rings and arcs appearance). Here some typical examples of bone tumors in the spine. Sclerotic bone lesions appear exclusively in middle aged black patients. 2010;35(22):E1221-9. It is nost commonly located on the posterior side of the distal meta-diaphysis of the femur. Central location most common with some expansion and cortical thinning. This 'neocortex' can be smooth and uninterrupted, but may also be focally interrupted in more aggressive lesions like GCT. (2007) ISBN:0781765188. Spine (Phila Pa 1976). Notice that CT depicts these lesions far better (red arrows). The lesion is predominantly calcified. CT of Sclerotic Bone Lesions: Imaging Features Differentiating Tuberous Sclerosis Complex with Lymphangioleiomyomatosis from Sporadic Lymphangioleiomymatosis1. The differential diagnosis mostly depends on the review of the conventional radiographs and the age of the patient. The diagnosis is usually established by a combination of imaging and the known presence of a primary tumor that is associated with sclerotic bone metastases. Another finding classic for Pagets disease is that it almost always starts at one end of a bone and then spreads toward the other end of the bone. Here Melorrheostosis of the ulna with the appearance of candle wax. This represents a thick cartilage cap. Azar A, Garner H, Rhodes N, Yarlagadda B, Wessell D. CT Attenuation Values Do Not Reliably Distinguish Benign Sclerotic Lesions From Osteoblastic Metastases in Patients Undergoing Bone Biopsy. When considering congenital causes of sclerotic lesions, benign causes such as bone islands or osteopoikilosis usually have a fairly typical appearance and are hard to mistake. These are infections and eosinophilic granuloma. Click here for more examples of chondroblastoma. The differential diagnosis for bone tumors is dependent on the age of the patient, with a very different set of differentials for the pediatric patient. Bone reacts to its environment in two ways either by removing some of itself or by creating more of itself. AJR 2005; 185:915-924. The evaluation of a solitary bony lesion in the spine may be more challenging and will often require additional diagnostic testing if benign imaging features are not present on MRI. Bone reacts to its environment in two ways either by removing some of itself or by creating more of itself. Well, generally, it means that it is due to a fairly slow-growing process. Osteoma consists of densely compact bone. Check for errors and try again. Here on a radiograph the typical calcifications in the chondroid matrix of an enchondroma. Hereditary sclerosing bone dysplasias result from some disturbance in the pathways involved in osteoblast or osteoclast regulation, leading to abnormal accumulation of bone. The diagnosis was fibrous dysplasia. Sclerotic bone metastases. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. In the case of benign, slowly growing lesions, the periosteum has time to lay down thick new bone and remodel it into a more normal-appearing cortex. Benign lesion consisting of well-differentiated mature bone tissue within the medullary cavity. On the left three bone lesions with a narrow zone of transition. Clin Orthop Relat Res. by Clyde A. Helms MRI features high sensitivity and high specificity for the demonstration of bone metastases in general and for assessing the bone marrow 2,3. The illustration on the left shows the preferred locations of the most common bone tumors. Another approach to the differential diagnosis of sclerotic bone lesions is to use the mnemonic I VINDICATE, which means 'I clear myself from accusation'. A juxtacortical chondrosarcoma has be considered in the differential diagnosis when a mineralized lesion adjacent to the cortical bone is seen. Enhancement after i.v. Macedo F, Ladeira K, Pinho F et al. This shows that differentiating a tumor from a reactive proces scan be quite difficult in some cases. In this case we see the pathognomonic triad of bone expansion, cortical thickening and trabecular bone thickening in the mixed lytic and sclerotic phase of Paget's disease of right hemipelvis. PET features high sensitivity in the detection of bone metastases especially 18 NaF-PET is suitable for the detection of sclerotic metastases since it shows tracer uptake in locations with osteoblastic activity and is more accurate than FDG-PET 3. 3, Increased uptake on bone scan associated with a solitary sclerotic lesion is atypical and therefore more worrisome, but largely unhelpful as there are many reports of bone islands having increased Tc-99 m hydroxydiphosphonate (HDP) uptake. Common: Metastases, multiple myeloma, multiple enchondromas. In patients Bone cements such as polymethyl methacrylate and calcium phosphates have been widely used for the reconstruction of bone. Metastatic sclerotic bone lesions present in three typical patterns, focal, variegated, or diffuse based on the histological origin of the primary tumor. Skeletal Radiol. Less common: Fibrous dysplasia, Brown tumors of hyperparathyroidism, bone infarcts. Contrast-enhanced T1-weighted MR image demonstrates heterogeneous enhancement of the mass with extensive surrounding edema. Accordingly, growth of osteochondromas is allowed until a patient reaches adulthood and the physeal plates are closed. Many sclerotic lesions in patients > 20 years are healed, previously osteolytic lesions which have ossified, such as: NOF, EG, SBC, ABC and chondroblastoma. brae in keeping with diffuse bone infarcts. The zone of transition is the most reliable indicator in determining whether an osteolytic lesion is benign or malignant (1). some benign entities in this region may mimic malignancy if analyzed using classical bone-tumor criteria, and proper patient management requires being familiar with these presentations. Plain radiograph and coronal T1-weighted contrast-enhanced fat-suppressed MR image of a mixed lytic and sclerotic lesion of the distal femoral diaphysis. The images show on the left a typical osteolytic NOF with a sharp sclerotic border. The MR image shows that the lesion has lobulated contours and nodular enhancement.

FIGURE 2.7 Computed tomography of osteoid osteoma. Radiographs are specific but suffer from low sensitivity 1. Bone cyst is one of the manifestations of CGL with AGPAT2 mutation. Small osteolytic lesion (up to 1.5 cm) with or without central calcification.

Donald Resnick, Mark J. Kransdorf. Detection of a solitary sclerotic bone lesion on CT or plain radiograph often creates a diagnostic dilemma. Usually stress fractures are easy to recognize. Breast cancer (usually mixed lytic/sclerotic), Bone islands do not have edema in the adjacent bone marrow or extension into surrounding soft tissue or adjacent bony destruction. Bone flare phenomenon was well described on bone scans; a study 25 revealed the appearance of new or worsening bone sclerosis at 3-month CT assessment in three of 67 castration-resistant prostate cancer (CRPC) patients undergoing systemic treatment. One of the first things you should notice about sclerotic bone lesions is whether they are single and focal, multifocal, or diffuse. Fibro-osseous lesion like fibrous dysplasia. Here an illustration of the most common sclerotic bone tumors. Other benign lesions, like solitary bone cyst, fibrous dysplasia, chondroblastoma and other benign bone tumors may become inert and may also become sclerotic. It is a feature of malignant bone tumors. Regarding bone disease in SM, increased sBT levels have been 493 associated with both bone sclerosis (due to unknown mechanisms) (8, 18, 19) and 494 osteoporosis (it has been hypothesized that tryptase could induce the production of 495 OPG (61)) (4, 17). There were other features that favored the diagnosis of a low-grade chondrosarcoma like a positive bone scan and endosteal scalloping of the cortical bone on an MRI (not shown). Brant WE, Helms CA. Sclerosis is usually the most prominent finding in subacute and chronic osteomyelitis. A Novel Classification System for Spinal Instability in Neoplastic Disease: An Evidence-Based Approach and Expert Consensus from the Spine Oncology Study Group. Radiologic Atlas of Bone Tumors Ossification in parosteal osteosaroma is usually more mature in the center than at the periphery. growth of osteohondroma in skeletally mature patients, irregular or indistinct surface of lesions, soft tissue mass with scattered or irregular calcifications. Non-ossifying fibroma (NOF) can be encoutered occasionally as a partial or completely sclerotic lesion. Here a partially calcified mass against the proximal humerus with involvement of the cortical bone on an axial CT image. {"url":"/signup-modal-props.json?lang=us"}, Niknejad M, Bell D, Tatco V, et al. Uncommonly it can be difficult to differentiate a stress fracture from a pathologic fracture, that occurs at the site of a bone tumor. Density measurements on CT scan revealed greater than 1,000 HU throughout the lesion. 2019;15:100205. Rapid growth of the mineralized mass is not uncommon. Teaching Point: Metastasis is the most common malignant rib lesion. in Ewing's sarcoma or lymphoma. Infection may be well-defined or ill-defined osteolytic, and even sclerotic. It is assumed that several tumor-derived growth factors increase osteoblast activity while osteoclast activity is restricted 3,4. sclerosing osteomyelitis of Garr, aggressive features might require an oncological referral and/or biopsy 1, history of malignancy will almost always require additional imaging, follow-up or oncologic referral, high CT attenuation values might help in the differentiation of bone island from osteoblastic metastases 5 but attenuation values should not be used exclusively for the assessment of sclerotic bone lesions 6, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. A brain MRI can . As part of the test, a healthcare professional takes a sample of the CSF The radiographic appearance and location are typical. In Section 2, we give the general technical route for classification, detection and segmentation of multiple-lesion.After that, in Section 3, the paper will review the recognition of multiple-lesion in six organ and tissue areas, including brain, eye, skin, breast, lung, and abdomen. In most cases of osteoid osteoma the radiographic appearance is determined by the reactive sclerosis. Azar A, Garner H, Rhodes N, Yarlagadda B, Wessell D. CT Attenuation Values Do Not Reliably Distinguish Benign Sclerotic Lesions From Osteoblastic Metastases in Patients Undergoing Bone Biopsy. However, the exact mechanism that leads to osteoblastic formation is not entirely elucidated. A Codman's triangle refers to an elevation of the periosteum away from the cortex, forming an angle where the elevated periosteum and bone come together. 2 ed. The pathogenesis of myeloma-related bone disease (MBD) is the imbalance of the bone-remodeling process, which results from osteoclast activation, osteoblast suppression, and the immunosuppressed bone marrow microenvironment. Mild mass effect on adjacent lung, diaphragm, and liver. In patients > 30 years, and particularly > 40 years, despite benign radiographic features, a metastasis or plasmacytoma also have to be considered Incidentally discovered, benign lesions also called enostoses, which are islands of cortical bone located in the cancellous bone. O'Sullivan G, Carty F, Cronin C. Imaging of Bone Metastasis: An Update. Unable to process the form. Here images of an osteosarcoma in the right femur. Bone metastases start with the tropism of cancer cells to the bone through different multi-step tumor-host interactions, as described by the . -. 5, In the cases with no known primary malignancy that are being followed with serial imaging, if the lesion increases in diameter by greater than 25% at 6 months or less, or greater than 50% at 12 months, open biopsy has been recommended by Brien et al. colon carcinoma, gastric carcinoma), ADVERTISEMENT: Supporters see fewer/no ads. The most common appearance is the mixed lytic-sclerotic. Etiology Our patient had lytic bone lesions in (femur) long bones and also sclerotic lesions in the pelvic which was .

Sclerotic Lesions of the Spine 1311. predominant hypointensity on all imaging sequences mimicking a sclerotic process due to a variety of fac- . Logistic regression analyses were used to assess the association of joint form and lesions on imaging for axSpA patients and controls. This solitary, uniformly high-density lesion with neither edema in the surrounding bone marrow nor extension into the surrounding soft tissue most likely represents a giant bone island. Differential diagnosis Unable to process the form. Urgency: Routine. Chordoma is usually seen in the spine and base of the skull. Distinguishing Untreated Osteoblastic Metastases From Enostoses Using CT Attenuation Measurements. Here a chondrosarcoma of the left iliac bone. Less dense on CT and more heterogeneous than bone islands. 4. SusanaBoronat, IgnasiBarber, VivekPargaonkar, JoshuaChang, Elizabeth A.Thiele . Radionuclide bone scan shows a classic "double density" sign of osteoid osteoma located in the tibia: markedly increased radioactivity in the center ( arrow) is related to the nidus, less active areas ( arrowheads) represent reactive sclerosis. The NK cell type is seen as a sheet of soft tissue in the nasal cavity with bone destruction and erosion without any sclerosis. Studies suggest that beyond joint wear and tear . See article: bone metastases. Growth has been demonstrated well after skeletal maturity. There are two kinds of mineralization: Chondroid matrix Here a rather wel-defined eccentric lesion which is predominantly sclerotic. Consider progression of osteohondroma to chondrosarcoma when cartilage cap measures > 10 mm. 1. This is a routine medical imaging report. Most bone tumors are solitary lesions. Solitary sclerotic bone (osteosclerotic or osteoblastic) lesions are lesions of bone characterized by a higher density or attenuation on radiographs or computer tomography compared to the adjacent trabecular bone. 2003;415(415 Suppl):S4-13. Here a patient with a mineralized mass in the soft tissues. 13. Resonance Imaging Saeed M. Bafaraj . Chang C, Garner H, Ahlawat S et al. Malignant transformation Enchondromas aswell as low-grade chondrosarcomas are frequently encountered as coincidental findings in patients who have a MRI or bone scan for other reasons. Non-ossifying fibroma which has been filled in. Metastases and multiple myelomaIn patients > 40 years metastases and multiple myeloma are the most common bone tumors.Metastases under the age of 40 are extremely rare, unless a patient is known to have a primary malignancy.Metastases could be included in the differential diagnosis if a younger patient is known to have a malignancy, such as neuroblastoma, rhabdomyosarcoma or retinoblastoma.
