Fluid-filled distension of the bursa with partial tearing of the supraspinatus tendon at its insertion (arrow)
Case Discussion
The bursa is "saddle bag" in morphology (seen on the sagittal view) and extends medially to the AC joint and inferiorly to the surgical neck of humerus. The presence of fluid indicates pathology either within the bursa (bursitis) or in adjacent structures, most notably the supraspinatus tendon.
