Occasionally slowly enlargement can be seen. Radiological hallmark: formation of a chondroid (cartilagenous) matrix, which presents as punctuated, stippled or popcorn-like calcifications. Differential Diagnosis in Orthopaedic Oncology. Patients with sclerotic lesions due to metastasis often have a history of prior malignant disease. In fact, in areas where sickle cell disease is common, this may be the leading cause of diffuse sclerotic bones. Typically a NOF presents as an eccentric well-defined lytic lesion, usually found as a coincidental finding. 2. On CT sclerotic bone metastases typically present as hyperdense lesions, but display a lower density than bone islands 5. Fibrous dysplasia and eosinophilic granuloma more commonly present as osteolytic lesions, but they can be sclerotic. Polyostotic lesions > 30 years Mirels H. Metastatic Disease in Long Bones: A Proposed Scoring System for Diagnosing Impending Pathologic Fractures. 6. 2 ed. Bone metastases are the most common malignancy of bone of which sclerotic bone metastases are less common than lytic bone metastases. Paget disease is a chronic disorder of unknown origin with increased breakdown of bone and formation of disorganized new bone. MRI also may detect the nidus, combined with abundant bone marrow and soft tissue edema. This benign reactive process is most commonly found adjacent to the cortex of phalanges of hands or feet (75%). colon carcinoma, gastric carcinoma), ADVERTISEMENT: Supporters see fewer/no ads. Notice the resemblance to a juxtacortical mass in another patient (right), which was a biopsy proven parosteal osteosarcoma. In breast cancer, metastases may present as lytic lesions that may become sclerotic expressing a favourable response to chemotherapy. As you can see, by just dropping the items that tend to cause generalized sclerosis, we have generated a fairly good differential for focal lesions. Consider peripheral chondrosaroma in growing osteochondromas with or without pain after closure of the physeal plate. {"url":"/signup-modal-props.json?lang=us"}, Yap K, Knipe H, Niknejad M, et al. 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 bone island larger than 1 cm is referred to as a giant bone island (12). How should one approach sclerotic bone disease? Imaging is often helpful in determining a diagnosis, and it can sometimes make a particular diagnosis nearly certain. A 30-year-old woman underwent a CT of the pelvis for endometriosis and an incidental lesion was found in the sacrum. 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. AJR Am J Roentgenol. Fibrous dysplasia can be monostotic or polyostotic. 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. Most bone tumors are solitary lesions. Materials and Methods Coronal T1W image shows lobulated margins and peripheral low SI due to the calcifications. Symptoms are usually absent, however, in adult patients with a chondroid lesion in a long bone, particularly of larger size, always consider low-grade chondrosarcoma. For those that are possibly cancerous, a biopsy is conducted to identify it. Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-21100, Mnemonic for focal sclerotic lesions (mnemonic). Osteoblastic metastatic disease (see Table 33.1): More often multiple with increased uptake on bone scan. 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. Bone reacts to its environment in two ways either by removing some of itself or by creating more of itself. 7. Radiographs are specific but suffer from low sensitivity 1. This is extremely common in Pagets disease but extremely uncommon with a blastic metastasis. Non-ossifying fibroma (NOF) can be encoutered occasionally as a partial or completely sclerotic lesion. 1988;17(2):101-5. 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. In order to classify osteolytic lesions as well-defined or ill-defined, we need to look at the zone of transition between the lesion and the adjacent normal bone. 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. Clin Orthop Relat Res. Finally, we conclude with a case of an incidentally presenting sclerotic vertebral body lesion. Metastases must be included in the differential diagnosis of any bone lesion, whether well-defined or ill-defined osteolytic or sclerotic in age > 40. Radiology. Infection may be well-defined or ill-defined osteolytic, and even sclerotic. 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 The NK cell type is seen as a sheet of soft tissue in the nasal cavity with bone destruction and erosion without any sclerosis. 7A, and 7B ). The images show on the left a typical osteolytic NOF with a sharp sclerotic border. A sclerotic lesion is an unusual hardening or thickening of your bone. It is assumed that several tumor-derived growth factors increase osteoblast activity while osteoclast activity is restricted 3,4. ADVERTISEMENT: Supporters see fewer/no ads. A Novel Classification System for Spinal Instability in Neoplastic Disease: An Evidence-Based Approach and Expert Consensus from the Spine Oncology Study Group. Rib metastases may be osteolytic, sclerotic, or mixed. Despite their remarkable clinical success, the low degradation rate of these materials hampers a broader clinical use. Osteopetrosis and pyknodysostosis are likewise hard to mistake for other entities since the bones are denser than in any other disorder, and the long bones tend to have very tiny medullary canals. The cortical bone and bone marrow compartment are not involved. Less dense on CT and more heterogeneous than bone islands. These are infections and eosinophilic granuloma. Both imaging modalities achieved only a moderate correlation with DEXA. Sclerotic Lesions of the Spine 1311. predominant hypointensity on all imaging sequences mimicking a sclerotic process due to a variety of fac- . Cortical destruction is a common finding, and not very useful in distinguishing between malignant and benign lesions. Resonance Imaging Saeed M. Bafaraj . Bker S, Adams L, Bender Y et al. In some locations, such as in the humerus or around the knee, almost all bone tumors may be found. Spinal lesions are commonly spotted on imaging tests. Particularly chronic osteomyelitis may have a sclerotic appearance. Density measurements on CT scan revealed greater than 1,000 HU throughout the lesion. This occurs in early knee osteoarthritis and indicates the potential for cartilage loss and misalignment of a knee compartment. Click here for more detailed information about NOF. Imaging of skull vault tumors in adults: Author: Pons Escoda, Albert Naval Baudin, Pablo . This part corresponds to a zone of high SI on T2-WI with FS on the right. Multiple enchondromas are seen in Morbus Ollier. Subungual exostoses are bony projections which arise from the dorsal surface of the distal phalanx, most commonly of the hallux. WSI digital slide: https://kikoxp.com/posts/4606. Hallmark of osteosarcoma is the production of bony matrix, which is reflected by the sclerosis seen on the radiograph. Detection of a solitary sclerotic bone lesion on CT or plain radiograph often creates a diagnostic dilemma. 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 Nancy M. Major, Clyde A. Helms and William J. Richardson. Radiographically, GCTs are eccentrically located radiolucent lesions with well-defined lytic 1B margins and geographic bone destruction. Case Report Med. Bone metastases start with the tropism of cancer cells to the bone through different multi-step tumor-host interactions, as described by the . Case 7: metastases from prostate carcinoma, Sclerotic bone pseudolesions - external artifact, bizarre parosteal osteochondromatous proliferation (Nora lesion), conventional intramedullary chondrosarcoma, dysplasia epiphysealis hemimelica (Trevor disease), solitary bone plasmacytoma with minimal bone marrow involvement, mixed lytic and sclerotic bone metastases, Lodwick classification of lytic bone lesions, Modified Lodwick-Madewell classification of lytic bone lesions. Abbreviations used: The most important determinators in the analysis of a potential bone tumor are: It is important to realize that the plain radiograph is the most useful examination for differentiating these lesions.CT and MRI are only helpful in selected cases. Adam Greenspan, Gernot Jundt, Wolfgang Remagen. These lesions may have ill-defined margins, but cortical destruction and an aggressive type of periosteal reaction may also be seen. Complete envelopment may occur. 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. Multiple myeloma is a hematologic malignancy of plasma cells that causes bone-destructive lesions and associated skeletal-related events (SREs). found incidentally on the imaging studies. T2-weighted MR image reveals a lobulated mass with high signal intensity. 2020;60(Suppl 1):1-16. Therefore, MRI and bone scan were performed. Mass displaces and involves both the right 10 th intercostal artery, as well as more superior right 9 th intercostal artery. {"url":"/signup-modal-props.json?lang=us"}, Niknejad M, Bell D, Tatco V, et al. Growth has been demonstrated well after skeletal maturity. Skeletal Radiol. It is a feature of malignant bone tumors. Sclerotic bone lesions are rare; commonly affects the axial skeleton (pelvis, spine, skull, ribs) and the patients are often symptomatic as opposed to the patients with lytic lesions who rarely have any symptoms. 33.1b), CT scan axial images (c), and bone scintigraphy (d). Some prefer to divide patients into two age groups: 30 years. You may have been surprised to see metastatic disease listed as a leading cause for diffuse sclerotic bones. Because of the large dimensions with soft tissue extension on plain radiograph and axial T2-weighted MR image, a high grade chondrosarcoma was suspected. The cause of sclerotic lesions was assessed histologically or by clinical and imaging follow-up. 12. 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. There are calcified strands within the soft tissues. Intense uptake on bone scintigraphy as we would expect in high grade chondrosarcoma. Systematic Approach of Sclerotic Bone Lesions Basis on Imaging Findings. CT These lesions usually regress spontaneously and may then become sclerotic. {"url":"/signup-modal-props.json?lang=us"}, Knipe H, Yap J, Masters M, et al. Surrounded by a prominent zone of reactive sclerosis due to a periosteal and endosteal reaction, which may obscure the central nidus. You can then customize the above differential for whichever pattern of sclerosis that you see. When you are considering osteonecrosis in your differential diagnosis, look at the joints carefully. 2022;51(9):1743-64.

Concerning the above factors the differential diagnosis includes the following lesions 1-3: sclerotic bone metastasis: might be solitary because no others are present or have been imaged, infection: e.g. In the group of malignant small round cell tumors which include Ewing's sarcoma, bone lymphoma and small cell osteosarcoma, the cortex may appear almost normal radiographically, while there is permeative growth throughout the Haversian channels. Plain radiograph in another patient shows irreglar mineralized lesion with elevation of the periosteum and cortical involvement. Kimura T. Multidisciplinary Approach for Bone Metastasis: A Review. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. It is barely visible within the bone, but an agressive periostitis is seen (arrow). Here Melorrheostosis of the ulna with the appearance of candle wax. Sclerotic bone metastases can arise from several different primary malignancies including 1-3: mucinous adenocarcinoma of the gastrointestinal tract (e.g. Diffuse skeletal infarcts can be a common cause of diffuse skeletal sclerosis. Click here for more examples of chondroblastoma. Sclerotic bone metastases. 2. Distinguishing Untreated Osteoblastic Metastases From Enostoses Using CT Attenuation Measurements. Bone marrow edema can happen with fractures and other serious bone or joint injuries. If the lesion grows more rapidly still, there may not be time for the bone to retreat in an orderly manner, and the margin may become ill-defined. Biopsy revealed dedifferentiated chondrosarcoma. 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. There are two kinds of mineralization: Chondroid matrix It can also be proven histologically. Here a 44-year old male with a mixed lytic and sclerotic mass arising from the fifth metacarpal bone. Magnetic resonance imaging of subchondral bone marrow lesions in association with osteoarthritis. Peripheral chondrosarcoma, arising from an osteochondroma (exostosis). Axial T1-weighted MR image shows homogeneous low signal intensity due to the compact bone apposition. Here a chondrosarcoma of the left iliac bone. The image on the right is of a different patient who has an old NOF that shows complete fill in. Yes, it is possible to have a clear lumbar puncture and still have Multiple Sclerosis (MS). CT-HU has stronger correlations with DEXA than MRI measurements. Wide zone of transition Most commonly encountered bone tumor in the small bones of the hand and foot. In the active phase there is multilaminar periosteal reaction and bone and soft tissue edema. MR usually shows a large amount of reactive changes in bone and soft tissue. 2003;415(415 Suppl):S4-13. Here, we showed that sBT values are higher in patients presenting 496 with bone loss . 2010;35(22):E1221-9. 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. For the unexpected bone lesions, the distinguishing anatomic features and a generalized imaging approach will be reviewed for four frequently encountered scenarios: chondroid lesions, sclerotic bone lesions, osteolytic lesions, and areas of focal marrow abnormality. 1991;167(9):549-52. 8. Notice how easily MRI depicts these lesions. After an injury, different types of fluid can build up in a bone. Here an illustration of the most common sclerotic bone tumors. The use of radiological imaging in medical care dates back to 1895 when Symptoms include pain, abnormal sensations, loss of motor skills or coordination, or the loss of certain bodily functions. Park S, Lee I, Cho K et al. Here a radiograph of the pelvis with a barely visible osteoblastic metastasis in the left iliac bone (blue arrow). Complete destruction may be seen in high-grade malignant lesions, but also in locally aggressive benign lesions like EG and osteomyelitis. Notice the lytic peripheral part with subtle calcifications. 2016;207(2):362-8. Bone islands can be large at presentation. 7. 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. Diffuse bony sclerosis (mnemonic) Last revised by Joshua Yap on 28 Jun 2022 Edit article Citation, DOI & article data A mnemonic for remembering the causes of diffuse bony sclerosis is: 3 M's PROOF Mnemonic 3 M's PROOF M: malignancy metastases ( osteoblastic metastases) lymphoma leukemia M: myelofibrosis M: mastocytosis S: sickle cell disease Enchondroma, the most commonly encountered lesion of the phalanges. Gadolinium is usually minimal or absent (see right image). 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). Matching the degradation rate of the materials with neo bone formation remains a challenge for bone-repairing materials. Common: Metastases, multiple myeloma, multiple enchondromas. The location of a bone lesion within the skeleton can be a clue in the differential diagnosis. Click here for more examples of eosinophilic granuloma. mutation, and both sclerotic and lytic bone lesions together for the first time. T2-weighted axial MR image demonstrates high signal intensity of the tumor in the metacarpal bone with extension of a lobulated soft tissue mass. The diagnosis was fibrous dysplasia. A cold bone scan is helpful in distinguishing the bone island from a sclerotic metastasis, whereas a warm bone scan is nondiagnostic. 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. 2014;71(1):39. Edema often present in the surrounding bone marrow. These are inert filled-in non-ossifying fibromas. Patients usually have sclerotic bone lesions before and lytic bone lesions after puberty. Cartilaginous tumors in particular chondrosarcoma may show endosteal scalloping, while a bone infarct does not. It is true that the usual appearance of skeletal metastases is that of focal lesions diffuse sclerosis occurs in only a small fraction of cases of skeletal metastases. However, a specific density range has not been specified for those terms 1. 1. Amsterdam: Elsevier, 1993. It is associated with near total fat loss, severe insulin resistance and hypoleptinemia leading to metabolic derangements.Case PresentationWe report a 25- year- old female with 1-Acylglycerol-3-phosphate-O-acyltransferase 2 (APGAT2) mutation, and both sclerotic and lytic bone lesions together for the first time. 2016;207(2):362-8. These tumors may be accompanied by a large soft tissue mass while there is almost no visible bone destruction. . In this paper, we review the recent years of literature on deep learning-based multiple-lesion recognition. 2018;10(6):156. The differential diagnosis mostly depends on the review of the conventional radiographs and the age of the patient. Chordoma is usually seen in the spine and base of the skull. FD is often purely lytic, but may have a groundglass appearance as the matrix calcifies. It could be blood or fluids released from fibrosis (scarred tissue) or necrosis (tissue death). Infection with a multilayered periosteal reaction. 7, Behrang Amini, Susana Calle, Octavio Arevalo, Richard M. Westmark, and Kaye D.

Parosteal osteosarcoma is a sarcoma that has it's origin on the surface of the bone. Starting on day 28, sclerotic changes surrounding the bone absorption area were detected. Brant WE, Helms CA. The radiological report should include a description of the following 2: location and size including the whole extent of disease load, pain attributable to the lesion (if known), Treatment of bone metastases, in general, is usually planned by a multidisciplinary team 10. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. Many sclerotic lesions in patients > 20 years are healed, previously osteolytic lesions which have ossified, such as: NOF, EG, SBC, ABC and chondroblastoma. Calcifications or mineralization within a bone lesion may be an important clue in the differential diagnosis. Here are links to other articles about bone tumors: Most bone tumors are osteolytic. 1. Parkinson's disease, multiple sclerosis, brain tumors and brain trauma [2]. Lippincott Williams & Wilkins. It is most commonly located in the outer table of the neurocranium or in a paranasal sinus. Ahuja S & Ernst H. Osteoblastic Bone Metastases in Medullary Thyroid Carcinoma. Once we have decided whether a bone lesion is sclerotic or osteolytic and whether it has a well-defined or ill-defined margins, the next question should be: how old is the patient?
