Enhanced MR imaging of the shoulder, and sternoclavicular and acromioclavicular joint arthritis in primary hemochromatosis.
Shoulder arthritis is a common feature of hemochromatosis. However, a combination of sternoclavicle (SC) and acromioclavicular (AC) joint involvement associated with shoulder is uncommonly seen. We describe the MR imaging findings of the shoulder and SC and AC joint in a patient with primary hemochromatosis. MRI of the left shoulder revealed inflammatory arthritis and 1-cm erosion of the humeral head, enlargement of the anterior glenoid labrum and formation of glenoid labral ovoid mass due to iron deposit. MRI of the AC joint showed inflammation and erosion with joint fluid. Significant contrast enhancement was noted at the SC joint due to inflammation.
