You can then customize the above differential for whichever pattern of sclerosis that you see. The sclerotic lesion in the humeral head could very well be a benign enchondroma based on the imaging findings. In the late stage of OA, the main feature is subchondral bone sclerosis, whose microarchitectural characteristics are elevated apparent density, increased bone volume, . Most common malignant bone tumor, which is almost always low-grade, Primary sites of origin: proximal long bones, around knee, pelvis and shoulder girdle, usually central and metaphyseal. Enchondroma is a fairly common benign cartilaginaous lesion which may present as an entirely lytic lesion without any calcification, as a dense calcified lesion or as a mixed leson with osteolysis and calcifications. Osteoblastic metastatic disease (see Table 33.1): More often multiple with increased uptake on bone scan. On the left three bone lesions with a narrow zone of transition. Differentiation of Predominantly Osteoblastic and Osteolytic Spine Metastases by Using Susceptibility-Weighted MRI. Sclerotic jaw lesions are not rare and are frequently encountered on radiographs and computed tomography (CT). 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. An ill-defined border with a broad zone of transition is a sign of aggressive growth (1). The most reliable indicator in determining whether these lesions are benign or malignant is the zone of transition between the lesion and the adjacent normal bone (1). 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. In some cases however the osteolytic nidus can be visible on the radiograph (figure). Radiographs typically show a geographic lytic or ground glass lesion with a well-defined, often extensively sclerotic margin, indicating its indolent nature. Distinguishing Untreated Osteoblastic Metastases From Enostoses Using CT Attenuation Measurements. Typical presentation: central lesion in metaphysis or diaphysis with a well defined serpentiginous border. 12. Bone cyst is one of the manifestations of CGL with AGPAT2 mutation. As current recommendations for tuberous sclerosis complex surveillance include renal MR performed i Chrondroid tumors are more frequently encountered than bone infarcts. Localisation: femur, tibia, hands and feet, spine (arch). In most cases of osteoid osteoma the radiographic appearance is determined by the reactive sclerosis. 105-118. However, cancers that metastasize to bone are very common. Adamantinoma in case of a sclerotic lesion with several lucencies of the tibia in a young patient. Osteomyelitis is a mimicker of various benign and malignant bone tumors and reactive processes that may be accompanied by reactive sclerosis. Signed by [redacted] on 1/17/2020 11:42 AM Narrative 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. A lucent, well-circumscribed lesion is seen with a surrounding thin sclerotic cortical rim on plain radiographs [ Figure 4 ]. Fundamentals of diagnostic radiology. Bone islands demonstrate uniformly low Patients usually have sclerotic bone lesions before and lytic bone lesions after puberty. Osteoblastic metastases have a lower fracture risk than lytic or mixed bone metastases 11-13. post-treatment appearance of any lytic bone metastasis. Here some typical examples of bone tumors in the spine. In the epiphysis we use the term avascular necrosis and not bone infarction. 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. Starting on day 28, sclerotic changes surrounding the bone absorption area were detected. CT scan is usually very helpful in detecting the nidus and differentiating osteoid osteoma from other sclerotic lesions like osteoblastoma, osteomyelitis, arthritis, stress fracture and enostosis. AJR 2005; 185:915-924. Diffuse bony sclerosis (mnemonic). Logistic regression analyses were used to assess the association of joint form and lesions on imaging for axSpA patients and controls. Office Phone: (517) 205-6750. Symptoms include pain, abnormal sensations, loss of motor skills or coordination, or the loss of certain bodily functions. 7. Fibrous dysplasia can be monostotic or polyostotic. 4, Although usually stable in size, bone islands may increase or decrease in size or disappear. Usually typical malignant features including permeative-motheaten pattern of destruction, irregular cortical destruction and aggressive (interrupted) periosteal reaction. 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. Here an incidental finding of several eccentric sclerotic lesions of the distal femur. Isaac A, Dalili D, Dalili D, Weber M. State-Of-The-Art Imaging for Diagnosis of Metastatic Bone Disease. 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. 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. When considering Pagets disease, it is extremely helpful to note whether there is associated bony enlargement. Studies suggest that beyond joint wear and tear . Notice the resemblance to a juxtacortical mass in another patient (right), which was a biopsy proven parosteal osteosarcoma. Osteoblastic bone metastases are characterized by increased bone formation 2. If there are multiple or polyostotic lesions, the differential diagnosis must be adjusted. Detection of a solitary sclerotic bone lesion on CT or plain radiograph often creates a diagnostic dilemma. {"url":"/signup-modal-props.json?lang=us"}, Yap K, Knipe H, Niknejad M, et al. Notice the numerous ill-defined osteoblastic metastases. Surrounded by a prominent zone of reactive sclerosis due to a periosteal and endosteal reaction, which may obscure the central nidus. Axial T1-weighted MR image shows homogeneous low signal intensity due to the compact bone apposition. 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. Systematic Approach of Sclerotic Bone Lesions Basis on Imaging Findings. Hall F & Gore S. Osteosclerotic Myeloma Variants. The lesson here is that when we are dealing with a very common disorder, even its less common presentations will be seen commonly. After an injury, different types of fluid can build up in a bone. It could be blood or fluids released from fibrosis (scarred tissue) or necrosis (tissue death). In the table the most common sclerotic bone tumors and tumor-like lesions in different age-groups are presented. Secondary bone cancer is much more common than primary bone . Notice that the cortical bone extends into the lesion. BallooningBallooning is a special type of cortical destruction.In ballooning the destruction of endosteal cortical bone and the addition of new bone on the outside occur at the same rate, resulting in expansion. Notice that the mineralization is predominantly in the periphery of the mass and that there is a lucent zone between the mass and the cortical bone. 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). Contrast-enhanced T1-weighted MR image demonstrates heterogeneous enhancement of the mass with extensive surrounding edema. Radiological atlas of bone tumours of the Netherlands Committee on Bone Tumors How should one approach sclerotic bone disease? Even though plain X-ray and CT would typically be used to follow a suspected bone island, MRI was chosen as the follow-up modality because the sacrum is an area not well seen on plain films due to overlying bowel gas and concern regarding radiation dose from multiple CT scans to the pelvis of a 30-year-old woman. However, the exact mechanism that leads to osteoblastic formation is not entirely elucidated. Here a radiograph of the pelvis with a barely visible osteoblastic metastasis in the left iliac bone (blue arrow). 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 8 of the 24 patients, 17 of 52 new sclerotic lesions (33%) had showed positive uptake on previous bone scans. The zone of transition only applies to osteolytic lesions since sclerotic lesions usually have a narrow transition zone. WSI digital slide: https://kikoxp.com/posts/4606. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. They usually affect posterior vertebral elements and their number and size increase with age. DD: Ganglion cyst, osteomyelitis, GCT, ABC, enchondroma. If the disorder it is reacting to is rapidly progressive, there may only be time for retreat (defense). Fundamentals of diagnostic radiology. Materials and Methods Bone reacts to its environment in two ways either by removing some of itself or by creating more of itself. Detecting a benign periosteal reaction may be very helpful, since malignant lesions never cause a benign periosteal reaction. This feature differentiates it from a juxtacortical tumor. Mixed lytic/sclerotic lesion of right posterolateral 10 th rib, with extensive aggressive-appearing periostitis, as well as a multilobulated soft tissue component. Gadolinium is usually minimal or absent (see right image). Chordoma is usually seen in the spine and base of the skull. 20 yo M w/ 5 cm lytic bone lesion in proximal tibia metaphysis, sharply demarcated w/ sclerotic rim. The image on the right is of a different patient who has an old NOF that shows complete fill in. 9. Edema often present in the surrounding bone marrow. Matching the degradation rate of the materials with neo bone formation remains a challenge for bone-repairing materials. 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. Fibrous dysplasia and eosinophilic granuloma more commonly present as osteolytic lesions, but they can be sclerotic. In fact, in areas where sickle cell disease is common, this may be the leading cause of diffuse sclerotic bones. Sclerotic osteoblastic metastases must be included in the differential diagnosis of any sclerotic bone lesion in a patient > 40 years. Rib metastases may be osteolytic, sclerotic, or mixed. Many important signaling . Amorphous mineralisation is present in most lesions. Eosinophilic Granuloma and infections should be mentioned in the differential diagnosis of almost any bone lesion in patients < 20 years. In this article we will discuss the differential diagnosis of sclerotic bone tumors and tumor-like lesions in more detail. Oncol Rev. On the right T2-WI with FS of same patient.. Resonance Imaging Saeed M. Bafaraj . This image is of a 20 year old patient with a sclerotic expansile lesion in the clavicle. 2010;35(22):E1221-9. Both of these entities may have an aggressive growth pattern. More heterogenous and irregular with bony trabecular destruction and possible extension beyond the confines of the cortex. Infection may be well-defined or ill-defined osteolytic, and even sclerotic. Calcifications or mineralization within a bone lesion may be an important clue in the differential diagnosis. Case Report Med. Brant WE, Helms CA. 1989. 2021;13(22):5711. Not infrequently encountered as coincidental finding at later age. Fisher C, DiPaola C, Ryken T et al. Yes, it is possible to have a clear lumbar puncture and still have Multiple Sclerosis (MS). Central location most common with some expansion and cortical thinning. Amsterdam: Elsevier, 1993. The differential for multifocal lesions happens to be identical to that for focal lesions. Here an image of a patient with chronic osteomyelitis. Most of the time, sclerotic lesions are benign. 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). DD: old SBC. and PD-L1 PET/CT (PD-L1 positivity is defined as having at least one lesion with radiotracer uptake over the . Donald Resnick, Mark J. Kransdorf. These lesions were possibly misinterpreted as new when applying WHO criteria. Notice that in all three patients, the growth plates have not yet closed. Here on a radiograph the typical calcifications in the chondroid matrix of an enchondroma. Lumbar CT-HU has the highest pooled correlation (r 2 =0.6) with both spine DEXA and lowest skeletal t-score followed by lumbar CT-HU with hip DEXA (r 2 =0.5) and lumbar MRI with hip (r 2 =0.44) and spine (r 2 =0.41) DEXA. Cortical destruction is a common finding, and not very useful in distinguishing between malignant and benign lesions. 1991;167(9):549-52. 2019;15:100205. Semin. This type of periostitis is multilayered, lamellated or demonstrates bone formation perpendicular to the cortical bone. Multiple enchondromas are seen in Morbus Ollier. Plain radiograph and coronal T1-weighted contrast-enhanced fat-suppressed MR image of a mixed lytic and sclerotic lesion of the distal femoral diaphysis. W. B. Saunders company 1995, by Mark J. Kransdorf and Donald E. Sweet Osteochondroma is a bony protrusion covered by a cartilaginous cap. Density measurements on CT scan revealed greater than 1,000 HU throughout the lesion. 33.1d).

Rohrmann, Jr., M.D., Endowment for Radiology Resident Educational Excellence, Michael and Rebecca McGoodwin Endowment for Radiology Resident and Fellow Training and Education, The Norman and Anne Beauchamp Endowed Fund for Radiology. A chondrosarcoma was diagnosed at biopsy. There are two patterns of periosteal reaction: a benign and an aggressive type. Accordingly, growth of osteochondromas is allowed until a patient reaches adulthood and the physeal plates are closed. The differential diagnosis mostly depends on the review of the conventional radiographs and the age of the patient. Differential diagnosis based on the periosteal reaction and the extensive edema: Here a patient with a juxtacortical sclerotic mass of the proximal humerus (left). Wide zone of transition When a reactive process is more likely based on history and imaging features, follow-up is sometimes still needed. Solitary sclerotic bone lesion. The contour of the subchondral bone plate was maintained until day 3, but it was absorbed just under the cartilage defect from day 7 to 14. Bone scintigraphy (99mTc MDP) is very sensitive for the detection of osteoblastic providing information on osteoblastic activity but suffers from specificity with a false-positivity rate ranging up to 40% 1. Osteoblastic metastases (2) Etiology There is a metastasis, which presents as a subtle sclerotic lesion in the humerus metaphysis. 6. In juxta-articular localisation, the reactive sclerosis may be absent. RT @JMGardnerMD: 20 yo M w/ 5 cm lytic bone lesion in proximal tibia metaphysis, sharply demarcated w/ sclerotic rim. Increased uptake on bone scan has been reported in bone islands, especially giant ones, but warrants imaging follow-up. 3. diffuse sclerotic metastases to the pelvis, sacrum and femurs. Cancers (Basel). Click here for more information about bone island. For example: Differential Diagnosis of Focal or Multifocal Sclerotic Bone Lesions. 1 When the vertebral lesion has no benign features, especially in the older adult patient, metastatic disease is always a significant consideration. Here two other lesions in different patients that proved to be chondrosarcoma. The subchondral bone is key to cartilage and joint health. Infection with a multilayered periosteal reaction. ImageBenign periosteal reaction in an osteoid osteoma.Large arrow indicates solid periosteal reaction.Small arrow indicates nidus. SusanaBoronat, IgnasiBarber, VivekPargaonkar, JoshuaChang, Elizabeth A.Thiele . 2 ed. 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. Sclerotic bone metastases. 7. One of the first things you should notice about sclerotic bone lesions is whether they are single and focal, multifocal, or diffuse. Sclerosis is present from either tumor new bone formation or reactive sclerosis. This proved to be a reactive calcification secondary to trauma. The radiographic appearance and location are typical. A surface osteosarcoma could be considered in the differential diagnosis. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. Sclerotic bone metastases typically present as radiodense bone lesions that are round/nodular with relatively well-defined margins 3. Fundamentals of Skeletal Radiology, second edition Plain radiograph in another patient shows irreglar mineralized lesion with elevation of the periosteum and cortical involvement. Ulano A, Bredella M, Burke P et al. It is assumed that several tumor-derived growth factors increase osteoblast activity while osteoclast activity is restricted 3,4. Differential diagnosis AJR Am J Roentgenol. Magnetic resonance imaging of subchondral bone marrow lesions in association with osteoarthritis. 2018;2018:1-5. Well, generally, it means that it is due to a fairly slow-growing process. Lippincott Williams & Wilkins. Several genes have been discovered that, when disrupted, result in specific types . Typically presents as a lytic lesion in a flat bone, vertebra or diaphysis of long bone. Focal sclerotic bony lesions (mnemonic). Physical examination and past medical history were normal and noncontributory respectively. When considering trauma as a cause for sclerotic lesions, remember to check and see if the areas involved are areas in the typical distribution for stress fractures. A high grade chondrosarcoma must be considered in the differential diagnosis. Here a 44-year old male with a mixed lytic and sclerotic mass arising from the fifth metacarpal bone. Polyostotic lesions > 30 years 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. Acute osteomyelitis is characterised by osteolysis. 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. 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. Spine (Phila Pa 1976). The mean and maximum attenuation were measured in Hounsfield units. 2018;10(6):156. Benign periosteal reaction 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. The homogeneous enhancement in the upper part with edema and cortical thickening are not typical for a low-grade chondrosarcoma. At the periphery of the infarct a zone of relative high signal intensity on T2WI may be found. However, if one sees sinus tracts associated with a sclerotic area, one should strongly consider osteomyelitis. The MR image shows that the lesion has lobulated contours and nodular enhancement. The radiograph shows typical bone infarcts in diaphysis and metaphysis of femur and tibia.. On MR imaging bone infarcts are characterized by irregulair serpentiginous margins with low signal intensity on both T1 and T2 WI and with intermediate to high fat signal in the center part. The homogeneous pattern is relatively uncommon compared to the heterogeneous pattern. colon carcinoma, gastric carcinoma), ADVERTISEMENT: Supporters see fewer/no ads. In aggressive periostitis the periosteum does not have time to consolidate. 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), What does it mean that a lesion is sclerotic? Malignant transformation Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-21100, Mnemonic for focal sclerotic lesions (mnemonic). Radiological hallmark: formation of a chondroid (cartilagenous) matrix, which presents as punctuated, stippled or popcorn-like calcifications. Osteoid osteoma (2) Because of the large dimensions with soft tissue extension on plain radiograph and axial T2-weighted MR image, a high grade chondrosarcoma was suspected. 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. Endosteal scalloping of the cortical bone can be seen in benign lesions like Fybrous dysplasia and low-grade chondrosarcoma. brae in keeping with diffuse bone infarcts. Bone scintigraphy can be either negative or show limited uptake. Fibro-osseous lesion like fibrous dysplasia. The location of a bone lesion within the skeleton can be a clue in the differential diagnosis. 8. Biopsy revealed dedifferentiated chondrosarcoma. Bone marrow edema can happen with fractures and other serious bone or joint injuries. Here an example of a patient with a stress fracture of the distal fibula. Both imaging modalities achieved only a moderate correlation with DEXA. Complete envelopment may occur. Small osteolytic lesion (up to 1.5 cm) with or without central calcification.
