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 …

Bone lesion with stippled calcification with a narrow zone of transition in the right humeral metaphysis. Appearances in keeping with an en (chondroma) of the humerus. This is a benign cartilaginous tumor of the medullary cavity. They typically occur …

Cartilage tumors share the characteristic production of a chondroid matrix with frequently typical matrix calcifications. They vary in severity from benign enchondromas and locally aggressive atypical cartilaginous tumors (ACT) to malignant chondrosarcomas.

Enchondromas are benign cartilaginous neoplasms that are usually solitary lesions in intramedullary bone occurring most commonly in small bones of the hands and feet. The distal femur and proximal humerus are other, less common locations.

Given the low risk for malignant transformation, we propose surveillance with plain radiographic follow-up for stable enchondromas every 3-6 months for the first year and then annually for at least three years of total follow-up.

Jul 10, 2023 · Enchondroma is a benign cartilaginous neoplasm. Malignant transformation is rare (< 1%) in a nonsyndromic setting. A 40 year old man presented with a bubbly appearing lytic lesion involving most of the distal phalanx of the left thumb.

4 days ago · Enchondroma. There is an expansile, lytic lesion of the 5th metacarpal (red arrow) containing amorphous matrix calcifications (white arrow) characteristic of an enchondroma.

5 days ago · Here is a radiology case (MRI ,X rays ,CT) of the diagnosis : Enchondroma, regarding the locations : Humerus - Proximal part, with the following gamuts : Bone marrow replacement, Geographic lesion with calcified matrix, Solitary osteosclerotic bone lesion

5 days ago · A secondary finding on a plain chest radiograph can be appreciated in the left humeral neck - there is a relatively large area of fluffy islands of spongiosclerosis. This finding is typical of chondroma.

15 hours ago · Background Differentiating chondroid tumors is crucial for proper patient management. This study aimed to develop a deep learning model (DLM) for classifying enchondromas, atypical cartilaginous tumors (ACT), and high-grade chondrosarcomas using CT images. Methods This retrospective study analyzed chondroid tumors from two independent cohorts. Tumors were segmented on CT images. A 2D ...
