Presentation
Elderly female presenting to her primary care physician with non-specific anterior shoulder pain.
Patient Data
Dyplasia of the glenoid labrum. No signs of old trauma.
shoulder MRI with intra articular contrast
Bony dysplasia of the glenoid labrum with persistance of the cartilagenous structures. There is also a superior labral tear with paralabral cysts.
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.
