Axial T2 WI from superior to inferior demonstrate partial undersurface tearing of the subscapularis. The arrow points to the deep fibers of the subscapularis, which is retracted and has become entrapped between the anterior glenoid and humeral head.

This was best visualized on axial imaging, displaying deep fibers of the subscapularis embedded between the glenoid and humeral head (Fig. 1A, B and C).
Sagittal (A) and Coronal (B) T2 WI redemonstrate partial tear of the subscapularis, proximal to its insertion on the lesser tuberosity. The coronal images (B) clearly depict the tear, with fluid seen where subscapularis muscle fibers normally run (arrow). Just above the fluid, several intact fibers are seen.

This was triangulated and confirmed on sagittal and coronel images (Fig. 2A and B).
Coronal PD images demonstrate complete tear of the supraspinatous with myotendonous retraction (arrow).

Ancillary findings included a complete tear of the supraspinatous with significant myotendinous retraction (Fig. 3).
