Chondroid lesions are extremely common incidental findings on musculoskeletal MRI studies, since the femur and humerus are the most common location for chondroid tumors of the appendicular skeleton. Malignant degeneration of a solitary …

2023年8月29日 · Chondroid nodules may have fatty marrow between them, also called interspersed or entrapped fat. This is best assessed on T1-weighted images and is present in lesions at the benign side of the spectrum, so in ACTs.

The long tubular bones, in particular the femur followed by proximal tibia and proximal humerus, are most frequently affected. Other sites of involvement include talus, calcaneus, patella, pelvic bones and less frequently the short tubular bones of hands and feet and flat bones.

2024年12月1日 · Enchondromas, also known as chondromas 7, are relatively common intramedullary hyaline cartilage neoplasms with benign imaging features. They share histologic features with low-grade chondrosarcoma and are sometimes classified under the umbrella term low-grade chondral series tumors.

Enchondromas are frequently found in the small long bones of your hands and feet. They’re the most common tumor found in the hand. Enchondromas can also develop in your body’s long bones, which include: Your femur (thigh bone). Your tibia (shin bone). Your humerus (upper arm bone). What are the symptoms of an enchondroma?

2010年4月10日 · There are two tumor-like lesions which may mimic a malignancy and have to be included in the differential diagnosis. These are infections and eosinophilic granuloma. Both of these entities may have an aggressive growth pattern.

Within the proximal tibial shaft there is a chondroid lesion present. There is no evidence of endosteal scalloping and no break in the cortex and there are no x-ray features to suggest sarcomatous degeneration of this lesion.

2020年1月1日 · Osteochondroma is a benign cartilage-capped tumor arising on the surface of bones and is the most common benign cartilage tumor of bone. More than 80% of osteochondromas are solitary; they are usually diagnosed by the second decade of life. There is a slight male predominance.

2017年4月24日 · 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 …

Chondrosarcoma is the most common primary malignant bone tumour after osteosarcoma (leaving aside multiple myeloma). A secondary chondrosarcoma can arise from a benign chondroid lesion such as an enchondroma or osteochondroma.
