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

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

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).
On MR imaging, hyperintense, well-defined, nodular mass lesions can be seen in fat suppression sequences (arrows).. Abbreviation: MR, magnetic resonance.

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

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).
(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.

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).
