Figure 9a. Arthroscopically confirmed partial tear of bicipital sling. (a-c) Transverse and (d) oblique coronal T1-weighted MR arthrographic images (700/10) obtained with fat saturation after intraarticular administration of dilute gadolinium compound. (a-c) Contrast agent is seen leaking (black arrow) in an irregular fashion through long focal cleft extending superiorly from lateral portion of rotator interval inferiorly and laterally through lateral portion of bicipital sling. Arrowhead = superior glenohumeral ligament, white arrow = coracohumeral ligament. (d) Thickened irregular tissue (arrow) is seen at area of bicipital sling above superior aspect of the lesser tuberosity (*), just medial to long head of biceps brachii tendon (arrowhead).
