Abstract

Synovial chondromatosis involving the bursa is uncommon, and those cases synovial chondromatosis within the bursa around the shoulder are especially rare. We report here a case of a 57-year-old male who had subdeltoid bursal subdeltoid bursal chondromatosis associated with osteochondral lesion of the proximal humerus and a rotator cuff tear. We also review the relevant literatures.

Keywords: synovial chondromatosis, osteochondral lesion

Figures and Tables

Figure 1

The left shoulder AP (A) and 30 degree caudal tilt (B) radiographs show oval shaped calcific loose bodies in the subdeltoid recess (thick arrow) and bony protrusion on greater tuberosity of the humerus (thin arrows).

Figure 2

T2-weighted coronal MR image of the left shoulder shows nearly full-thickness tear of supraspinatus tendon (arrow).

Figure 3

T1-weighted coronal (A), T2-weighted coronal (B) and axial (C) MR images of the left shoulder show two loose bodies in the subdeltoid recess (arrows) and bony protrusion on greater tuberosity of the humerus (asterix).

Figure 4

Arthroscopic findings show a large chondral loose body in subdeltoid recess (A) and cobble-stone appearance cartilage formation on the lateral side of the humeral head (B).

Figure 5

Gross specimen of loose bodies.

Figure 6

Arthroscopic findings show tear of supraspinatus (A) and repaired supraspinatus after surgery (B).

Figure 7

Microscopic finding of synovial loose body demonstrates cartilaginous metaplasia (thick arrow) beneath synovial surface (thin arrow) (Hematoxylin-Eosin stain, original magnification ×150).
