Case Discussion

This patient presented to her primary care physician with anterior shoulder pain without trauma. A conventional shoulder radiograph showed an atypical, smoothly delineated, sclerotically lined shape of the glenoid fossa that did not closely follow the humeral head. The reading musculoskeletal radiologist recommended a shoulder MRI to confirm glenoid dysplasia. As detailed in the referenced article, the presentation of glenoid dysplasia is in two peaks - one in adolescence due to an inherently less stable shoulder manifesting at increased athletic participation and one later in life presenting with typical degenerative complaints where the dysplasia might play a minor role but may also be an incidental finding. This patient also had a superior labral tear with paralabral cysts.
