Imaging Review of Subscapularis Tendon and Rotator Interval Pathology

Figure 9

A 67-year-old man with persistent pain after a left shoulder dislocation. Axial T2-weighed FS MRI (a) shows a partial articular surface tear of the subscapularis tendon (large arrow) with mild medial displacement of the long head of the biceps tendon (arrowhead). Also evident are an osseous Bankart lesion (ellipse) and the corresponding Hill–Sachs deformity (two short arrows). The full extent of the Hill–Sachs depression is best appreciated in the axial PD-weighted MRI (b), consistent with recent anterior dislocation. Coronal PD-weighted MRI (c) demonstrates a superior labral tear with the displacement of a portion of labrum (arrow) into the glenohumeral joint space. Sagittal oblique T2-weighed FS MRI (d) shows an intrasubstance tear of the genu of the long head of the biceps (arrows).
