Shoulder pain Note that evaluation of the pectoralis musculature is limited but within these limits, the visualized portions are unremarkable.HUMERUS
1. Although limited by lack of intra-articular contrast, findings suggestive of labral tear, particularly anteriorly and superiorly. Cystic changes within the humeral head along with possible additional posterior labral pathology raises the question of posterosuperior glenoid (internal) impingement.2. Lobulated focus within the mid shaft of the diaphysis may represent cartilaginous lesion. There is no soft tissue component but CT may be of benefit to determine the presence of cartilaginous or osteoid matrix. Regardless, short-term follow-up is recommended given the history of pain in the area.3. Small focus of increased signal within the brachialis muscle laterally along the mid shaft of the diaphysis may represent a small contusion.
