An articular-surface tear with an intratendinous horizontal splitting centered at the supraspinatus footprint/tendon attachment to the greater tuberosity mainly anteriorly with extension into the critical zone. It has about 10mm AP dimension, and >3mm depth, involving more than 70% of tendon thickness. Coracoacromial arch evaluation reveals: a type 2 acromial process with lateral tilt, reduced impingement interval to 5.5-6mm, and underlying supraspinatus tendon thinning. A low lateral acromial angle <66 degrees.
Degenerative changes within the horizontal intra-articular portion of the long head biceps tendon just at/distal to biceps–labral anchor, with no complete tear.
An area of increased signal intensity at the base of the superior labrum was noted from 11:00-1:00 as compatible with the SLAP lesion possibly extending into the biceps anchor.
