Glenoid dysplasia: radiographic and CT arthrographic findings.

A 60-year-old man with dysplasia of the glenoid and a rotator cuff tear is reported on. Because of the tear, CT arthrography was performed, offering an opportunity to evaluate the various soft tissue abnormalities accompanying glenoid dysplasia. Marked thickening of the glenoid cartilage and labrum was apparent, as well as an abnormal posterolateral orientation of the glenoid cavity. A deep notch was observed along the central portion of the glenoid cartilage. Furthermore the middle glenohumeral ligament appeared thickened and cordlike.
