Abstract
OBJECTIVE: To report an unusual combination of paraglenoid labral cyst and labral tear with chondral defect of the humeral head. CLINICAL PRESENTATION AND INTERVENTION: A 34-year-old man presented with right shoulder pain. Conventional MR imaging showed paraglenoid labral cyst. MR arthrography revealed a humeral chondral defect and labral tear associated with paraglenoid labral cyst, and a defect of the posterior inferior labrum extending to the superior labrum and humeral chondral defect. The patient underwent arthroscopic surgery. CONCLUSION: This case showed the importance of MR arthrography in a case that involved an unusual combination of paraglenoid labral cyst and labral tear with chondral defect.
