Radiographs and a CT (Figure 1) were obtained revealing a lytic lesion in the right humeral head with an associated soft tissue mass.
Coronal T2-weighted, fat suppressed MR image of the right shoulder also demonstrating the humeral head lesion (arrow). Abnormal signal involving the rotator cuff (arrowheads) was confirmed to represent full thickness tearing on additional images. Study was degraded by patient motion. [Powerpoint Slide]

In addition to the tumor, a preoperative MRI (Figure 2) also showed a recurrent full thickness tear of the supraspinatus and infraspinatus tendons with significant medial retraction of the torn tendons and severe muscle atrophy.
Initial radiographs of the reverse shoulder prosthesis were normal. [Powerpoint Slide]

Because of his irreparable rotator cuff tear, a reverse shoulder arthroplasty was performed (Figure 3) rather than a conventional total shoulder arthroplasty at the time of the giant cell tumor resection.
