case_images: Anterioposterior (A) and lateral (B) radiographs of elbow.. Note: Chodral erosions were seen at the anterior and posterior aspects of the humerus with arrows.

case_images: f1-oajsm-6-225
case_images: In radiological evaluation, it was seen that there was narrowing in the joint space and cortical irregularity in the anterior region (Figure 1).
case_images: On CT scan, chondral erosions can be seen posterior to the elbow joint in axial sections with arrow.. Abbreviation: CT, computerized tomography.

case_images: On computerized tomography (CT) scan, it was seen that there was soft tissue swelling at the right elbow joint, and cortical erosive changes in the distal humerus (Figure 2).
case_images: On MR imaging, hyperintense, well-defined, nodular mass lesions can be seen in fat suppression sequences (arrows).. Abbreviation: MR, magnetic resonance.

case_images: On magnetic resonance (MR) imaging, hyperintense, well-defined, nodular mass lesions were seen in fat suppression sequences (Figure 3).
case_images: Chondral components removed during (A and B) and after (C and D) surgery can be seen.

case_images: Again, numerous rigid, free chondral loose bodies, which extended to the radius head and a process inside the joint, were removed following capsulotomy (Figure 4).
case_images: (A) Lesion consisting of mature, lobulated cartilage tissue of varying sizes (H&e, 10x). (B) Chondrocytes forming lobular structures within well-defined chondroid matrix (H&e, 40x). (C) Chondrocytes displaying polygonal nuclei with clear cytoplasm.. Notes: Cells have uniform appearance without pleomorphism or atypia. A few binuclear cells are seen while no mitotic figure is observed (H&e, 100x).. Abbreviation: H&E, hematoxylin and eosin.

case_images: In the histopathological evaluation of the chondral loose bodies that were removed, SC was confirmed by observation of well-defined chondrocytes and mature cartilage tissues with lobulation (Figure 5).
