There is a metastasis, which presents as a subtle sclerotic lesion in the humerus metaphysis. Fibrous dysplasia can be monostotic or polyostotic. 1. 2021;13(22):5711. A sclerotic border especially indicates poor biological activity. Here on a radiograph the typical calcifications in the chondroid matrix of an enchondroma. Fibrous dysplasia, enchondromas, EG, Mets and myeloma, Hyperparathyroidism, Infection. A periosteal reaction is a non-specific reaction and will occur whenever the periosteum is irritated by a malignant tumor, benign tumor, infection or trauma. Continue with the MR-images. A mnemonicfor remembering the causes of diffuse bony sclerosis is: ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. A benign type of periosteal reaction is a thick, wavy and uniform callus formation resulting from chronic irritation. Click here for more examples of chondrosarcoma. They usually affect posterior vertebral elements and their number and size increase with age. ImageBenign periosteal reaction in an osteoid osteoma.Large arrow indicates solid periosteal reaction.Small arrow indicates nidus. Degenerative subchondral cyst: epiphyseal, Chondroid matrix in cartilaginous tumors like enchondromas and chondrosarcomsa. Complete envelopment may occur. SWI:low signal intensity on the inverted magnitude and phase images 9. Here a chondrosarcoma of the left iliac bone. Rib lesions detected on bone scintigraphy often require further characterization with radiography or CT to improve specificity (Figs. This feature differentiates it from a juxtacortical tumor. 6. How should one approach sclerotic bone disease? It may be spiculated and interrupted - sometimes there is a Codman's triangle. On CT sclerotic bone metastases typically present as hyperdense lesions, but display a lower density than bone islands 5. -. Bone cyst is one of the manifestations of CGL with AGPAT2 mutation. 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. Urgency: Routine. The use of radiological imaging in medical care dates back to 1895 when 1988;17(2):101-5. Halo of increased signal on T2 W images about the low signal central lesion is suggestive of metastatic disease. Several genes have been discovered that, when disrupted, result in specific types . Mass displaces and involves both the right 10 th intercostal artery, as well as more superior right 9 th intercostal artery. Resonance Imaging Saeed M. Bafaraj . The chondroid matrix is of a variable amount from almost absent to dens compact chondroid matrix. . 1. Society of Skeletal Radiology- White Paper. Multiple enchondromas are seen in Morbus Ollier. Here are links to other articles about bone tumors: Most bone tumors are osteolytic. This type of periostitis is multilayered, lamellated or demonstrates bone formation perpendicular to the cortical bone. Radiologe. Osteoblastic bone metastases are characterized by increased bone formation 2. Bone islands demonstrate uniformly low 9. The differential for multifocal lesions happens to be identical to that for focal lesions. They can affect any bone and be either benign (harmless) or malignant (cancerous). Usually stress fractures are easy to recognize. Mixed lytic and sclerotic bone metastases are characterized by the presence of both components, that is areas of bone destruction and areas of increased bone formation within one metastatic tumor deposit or one primary tumor that features both kinds of bone metastases, namely osteolytic and osteoblastic metastases 1. Cortical destruction (3) A lumbar puncture (LP) is a diagnostic procedure used to obtain a sample of cerebrospinal fluid (CSF) to look for signs of infection or inflammation. Strahlenther Onkol. Radiology. Another approach to the differential diagnosis of sclerotic bone lesions is to use the mnemonic I VINDICATE, which means 'I clear myself from accusation'. Macedo F, Ladeira K, Pinho F et al. Etiology Most commonly originate from prostate and breast cancer and less frequently from lung cancer, lymphoma or carcinoid. Ali Mohammed Hammamy R, Farooqui K, Ghadban W. Sclerotic Bone Metastasis in Pulmonary Adenocarcinoma. Metastases must be included in the differential diagnosis of any bone lesion, whether well-defined or ill-defined osteolytic or sclerotic in age > 40. The most common focal metastatic lesions originate from the breast (37%), lung (15%), kidney (6%), and thyroid (4%) 43. Click here for more examples of chondroblastoma. 1, The classic bone island has a spiculated or paintbrush border and is much denser on CT than a osteoblastic metastasis. 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. Small zone of transitionA small zone of transition results in a sharp, well-defined border and is a sign of slow growth.A sclerotic border especially indicates poor biological activity. In this chapter, we will discuss key imaging features that strongly indicate the lesion is benign and those that warn further evaluation is warranted. Particularly chronic osteomyelitis may have a sclerotic appearance. CT Usually one bone is involved. Multiple enchondromas and hemangiomas are seen in Maffucci's syndrome. Sclerotic Lesions of the Spine 1311. predominant hypointensity on all imaging sequences mimicking a sclerotic process due to a variety of fac- . Here a radiograph of the pelvis with a barely visible osteoblastic metastasis in the left iliac bone (blue arrow). Notice how easily MRI depicts these lesions. The NK cell type is seen as a sheet of soft tissue in the nasal cavity with bone destruction and erosion without any sclerosis. Home. Growth of osteochondroma in skeletally mature patient, Irregular or indistinct surface of lesions, focal lucent regions in interior of lesions, presence of soft tissue mass with scattered or irregular calcifications. Infections, a common tumor mimicker, are seen in any age group. The subchondral bone is key to cartilage and joint health. giant cell tumor, metastasis, and myeloma; (3) sclerotic . 2014;71(1):39. Osteoblastic Metastatic Lesions. Distinction of Long Bone Stress Fractures from Pathologic Fractures on Cross-Sectional Imaging: How Successful Are We? MRI features high sensitivity and high specificity for the demonstration of bone metastases in general and for assessing the bone marrow 2,3. The homogeneous pattern is relatively uncommon compared to the heterogeneous pattern. Plain radiograph in another patient shows irreglar mineralized lesion with elevation of the periosteum and cortical involvement. by Mulder JD, et al. The radiographic appearance and location are typical. This benign reactive process is most commonly found adjacent to the cortex of phalanges of hands or feet (75%). 2020;60(Suppl 1):1-16. Unable to process the form. {"url":"/signup-modal-props.json?lang=us"}, Yap K, Knipe H, Niknejad M, et al. The sclerotic lesion in the humeral head could very well be a benign enchondroma based on the imaging findings. As part of the test, a healthcare professional takes a sample of the CSF Common: Metastases, multiple myeloma, multiple enchondromas. 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. However, cancers that metastasize to bone are very common. Here a patient with a broad-based osteochondroma with extension of the cortical bone into the stalk of the lesion. 12. MRI shows large tumor within the bone and permeative growth through the Haversian channels accompanied by a large soft tissue mass, which is barely visible on the X-ray. 4 , 5 , 6. 2 ed. CT-HU has stronger correlations with DEXA than MRI measurements. Radiographic features that should raise the suspicion of malignant transformation on plain radiographs or CT include: Here the reactive sclerosis is the most obvious finding on the X-ray. Brant WE, Helms CA. Sclerotic bone metastases typically present as radiodense bone lesions that are round/nodular with relatively well-defined margins 3 . Wayne State University, Orthopaedic Surgery, MI, 2007 University of Texas Southwestern Medical School, Surgery, TX, 2002 The role of imaging in SN lymphomas is to identify the primary site of disease, site for biopsy and to map the lesion in its entirety in cases of patients undergoing radiotherapy [ 15, 21 ]. Well, generally, it means that it is due to a fairly slow-growing process. Growth of the osteochondroma takes place in the cap, corresponding with normal enchondral growth at the growth plates. Aggressive periosteal reaction On the right T2-WI with FS of same patient.. 4, Although usually stable in size, bone islands may increase or decrease in size or disappear. 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. (white arrows). AJR Am J Roentgenol. However, if one sees sinus tracts associated with a sclerotic area, one should strongly consider osteomyelitis. Fibro-osseous lesion like fibrous dysplasia. NOF, fibrous dysplasia, multifocal osteomyelitis, enchondromas, osteochondoma, leukemia and metastatic Ewing' s sarcoma. Most bone tumors are solitary lesions. For those that are possibly cancerous, a biopsy is conducted to identify it. This part corresponds to a zone of high SI on T2-WI with FS on the right. Despite their remarkable clinical success, the low degradation rate of these materials hampers a broader clinical use. Materials and Methods 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. Magnetic resonance imaging of subchondral bone marrow lesions in association with osteoarthritis. Cartilaginous tumors in particular chondrosarcoma may show endosteal scalloping, while a bone infarct does not. 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 Hereditary sclerosing bone dysplasias result from some disturbance in the pathways involved in osteoblast or osteoclast regulation, leading to abnormal accumulation of bone. 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. AJR 2000; 175:261-263. Density measurements on CT scan revealed greater than 1,000 HU throughout the lesion. The differential diagnosis of bone lesions that result in bony sclerosis will be given. Clin Orthop Relat Res. We provide care in several areas of orthopedics, such as: hand and wrist care, foot and ankle care, and joint replacement. Sclerotic bone lesions at abdominal magnetic resonance imaging in children with tuberous sclerosis complex. 1. T2-weighted MR image reveals a lobulated mass with high signal intensity. The lesion is predominantly calcified. Giant cell bone tumors are usually benign (not cancerous) but the malignant form can affect the legs, especially near the knees. AJR Am J Roentgenol. Chang C, Garner H, Ahlawat S et al. The benign type is seen in benign lesions such as benign tumors and following trauma. Distinct phenotypes are described: osteoblastic, the more common osteolytic and mixed. Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-8429. Sclerotic means that the lesions are slow-growing changes to your bone that happen very gradually over time. Symptoms include pain, abnormal sensations, loss of motor skills or coordination, or the loss of certain bodily functions. Coronal T1W image shows lobulated margins and peripheral low SI due to the calcifications. Finally other clues need to be considered, such as a lesion's localization within the skeleton and within the bone, any periosteal reaction, cortical destruction, matrix calcifications, etc. In this article we will discuss the differential diagnosis of sclerotic bone tumors and tumor-like lesions in more detail. Notice the resemblance to a juxtacortical mass in another patient (right), which was a biopsy proven parosteal osteosarcoma.

Sclerotic bone metastases typically present as radiodense bone lesions that are round/nodular with relatively well-defined margins 3. In juxta-articular localisation, the reactive sclerosis may be absent. Lippincott Williams & Wilkins. 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), A bone island larger than 1 cm is referred to as a giant bone island (12).

A cold bone scan is helpful in distinguishing the bone island from a sclerotic metastasis, whereas a warm bone scan is nondiagnostic. Enchondroma, the most commonly encountered lesion of the phalanges. An ill-defined border with a broad zone of transition is a sign of aggressive growth (1). Occasionally slowly enlargement can be seen. 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). 13. Polyostotic lesions > 30 years Tumor Pathology- Bone Lesion Bone Tumor Osteomyelitis When you identify a bone lesion, follow this basic checklist to help you accurately describe the lesion and narrow your differential diagnosis: Bone Tumors and Tumorlike Conditions: Analysis with Conventional Radiography Theodore T. Miller Radiology 2008 246:3, 662-674 In patients In patients > 30 years, and particularly > 40 years, despite benign radiographic features, a metastasis or plasmacytoma also have to be considered On the left three bone lesions with a narrow zone of transition. CT imaging example of the location pattern of sclerotic bone lesions in the skull, spine, and pelvis of TSC patients and control subjects. This shows that differentiating a tumor from a reactive proces scan be quite difficult in some cases. For example: Differential Diagnosis of Focal or Multifocal Sclerotic Bone Lesions. The differential diagnosis mostly depends on the age of the patient and the findings on the conventional radiographs. 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. Bone metastases are the most common malignancy of bone of which sclerotic bone metastases are less common than lytic bone metastases. Ulano A, Bredella M, Burke P et al. Sclerotic bone lesions are commonly detected by abdominal MRI in children with tuberous sclerosis complex. . Small osteolytic lesion (up to 1.5 cm) with or without central calcification. Sclerosis can also be reactive, e.g. Click here for more examples of eosinophilic granuloma. Incidentally discovered, benign lesions also called enostoses, which are islands of cortical bone located in the cancellous bone. At the 1-year follow-up, the lesion was completely stable and no additional follow-up was recommended in the absence of symptoms. Amsterdam: Elsevier; 1993. Osteoid osteoma (2) Metastatic sclerotic bone lesions present in three typical patterns, focal, variegated, or diffuse based on the histological origin of the primary tumor. Bone reacts to its environment in two ways either by removing some of itself or by creating more of itself. This could be an osteoblastic metastasis or an osteolytic metastasis that responded to chemotherapy. 33.1a) and sagittal short tau inversion recovery (STIR; Fig. Enhancement after i.v. Radiological atlas of bone tumours of the Netherlands Committee on Bone Tumors 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. (2005) ISBN: 9780721602707 -. Differentiation of Predominantly Osteoblastic and Osteolytic Spine Metastases by Using Susceptibility-Weighted MRI. Multiple myeloma is a hematologic malignancy of plasma cells that causes bone-destructive lesions and associated skeletal-related events (SREs). 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. Bone marrow edema can happen with fractures and other serious bone or joint injuries. World J Radiol. Top five location of bone tumors in alphabethic order: Aneurysmal Bone Cyst -tibia, femur, fibula, spine, humerusAdamantinoma -tibia shaft, mandibleChondroblastoma -femur, humerus, tibia, tarsal bone (calc), patellaChondromyxoid fibroma - tibia, femur, tarsal bone, phalanx foot, fibulaChondrosarcoma - femur, rib, iliac bone, humerus, tibiaChordoma -sacrococcygeal, spheno-occipital, cervical, lumbar, thoracicEosinophilic Granuloma -femur, skull, iliac bone, rib, vertebraEnchondroma -phalanges of hands and feet, femur, humerus, metacarpals, ribEwing's sarcoma - femur, iliac bone, fibula, rib, tibiaFibrous dysplasia - femur, tibia, rib, skull, humerusGiant Cell Tumor - femur, tibia, fibula, humerus, distal radiusHemangioma - spine, ribs, craniofacial bones, femur, tibiaLymphoma - femur, tibia, humerus, iliac bone, vertebraMetastases - vertebrae, ribs, pelvis, femur, humerusNon Ossifying Fibroma - tibia, femur, fibula, humerusOsteoid osteoma - femur, tibia, spine, tarsal bone, phalanxOsteoblastoma - spine, tarsal bone (calc), femur, tibia, humerusOsteochondroma - femur, humerus, tibia, fibula, pelvisOsteomyelitis - femur, tibia, humerus, fibula, radiusOsteosarcoma -femur, tibia, humerus, fibula, iliac boneSolitary Bone Cyst -proximal humerus, proximal femur, calcaneal bone, iliac bone. Our patient had lytic bone lesions in (femur) long bones and also sclerotic lesions in the pelvic which was . Sclerosing bone dysplasias are skeletal abnormalities of varying severity with a wide range of radiologic, clinical, and genetic features. Should be included in the differential diagnosis of young patient with multiple lucent lesions (Langerhans cell histiocytosis). None of the patients had undergone prior treatment for the metastases. Patients with sclerotic lesions due to metastasis often have a history of prior malignant disease. The use of PET/CT imaging with new radiotracers enables a non-invasive assessment of the presence of the target of treatment in the whole body and provides the possibility to combine functional information with anatomical details. {"url":"/signup-modal-props.json?lang=us"}, Gaillard F, Knipe H, Weerakkody Y, et al. It can differentiate predominantly osteoblastic from osteolytic bone metastases 9 as well as easily demonstrate and assess complications such as pathological fractures or spinal cord compression 2,3. It is assumed that several tumor-derived growth factors increase osteoblast activity while osteoclast activity is restricted 3,4. Well, generally, it means that it is due to a fairly slow-growing process. This is especially true when the injury involves the spine, hip, knees, or ankle. The zone of transition only applies to osteolytic lesions since sclerotic lesions usually have a narrow transition zone. 1. These lesions may have ill-defined margins, but cortical destruction and an aggressive type of periosteal reaction may also be seen. Here images of an osteosarcoma in the right femur. Ulano A, Bredella M, Burke P et al. 2015;7(8):202-11. What does it mean that a lesion is sclerotic? ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. 7. A juxtacortical chondrosarcoma has be considered in the differential diagnosis when a mineralized lesion adjacent to the cortical bone is seen. 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. {"url":"/signup-modal-props.json?lang=us"}, Niknejad M, Bell D, Tatco V, et al. Mnemonic for multiple oseolytic lesions: FEEMHI: Intense uptake on bone scintigraphy as we would expect in high grade chondrosarcoma. Hallmark of osteosarcoma is the production of bony matrix, which is reflected by the sclerosis seen on the radiograph. Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-10490, {"containerId":"expandableQuestionsContainer","displayRelatedArticles":true,"displayNextQuestion":true,"displaySkipQuestion":true,"articleId":10490,"questionManager":null,"mcqUrl":"https://radiopaedia.org/articles/sclerotic-bone-metastases/questions/1747?lang=us"}. The epiphysis, metaphysis and diaphysis may be involved. A sclerotic lesion is an unusual hardening or thickening of your bone. Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-22391. This is an example of progression of an osteochondroma to a peripheral chondrosarcoma. There are two tumor-like lesions which may mimic a malignancy and have to be included in the differential diagnosis. A T1w/T2-weighted (T2w) hypointense nonexpansile lesion is seen involving the sacrum (asterisk). Radiographically, GCTs are eccentrically located radiolucent lesions with well-defined lytic 1B margins and geographic bone destruction. Growth of osteochondromas at adult ages, which is characterized by a thick cartilaginous cap (high SI on T2WI) should raise the suspicion of progression to a peripheral chondrosarcoma. Consider progression of osteohondroma to chondrosarcoma when cartilage cap measures > 10 mm.
