31-year-old female Reason: history of multiple cancers, questionable lucency on XR. History: c/o pain in left shoulder. Decreased ROM There is mild heterogeneity of the medullary cavity of the humeral diaphysis which may reflect residual red marrow, but we see no focal lesion. There is a broad based bony excrescence along the posterolateral aspect of the proximal humeral diaphysis that may represent a small exostosis. The remainder of the humerus is unremarkable. As the field of view was enlarged to include the entire humerus, evaluation of the shoulder is limited. The acromion process is hypoplastic. We see no signal abnormality within the rotator cuff, although small tears could be missed on this examination. There is mild edema and enhancement between the distal clavicle and coracoid process. Prior radiographs suggest an anomalous coracoclavicular articulation and, hence, this edema and enhancement may represent a synovitis perhaps due to prior injury, or, perhaps a sprain of the coracoclavicular ligament. We see no fracture.
1. Broad based exostosis along proximal aspect of the humerus. We see no intramedullary humeral lesion. 2. Coracoclavicular edema and enhancement may represent synovitis at an anomalous articulation or, perhaps, a sprain of the coracoclavicular ligament.
