Two patients with clinically relevant anomalies of the long head of the biceps brachii tendon (LHBT) are presented with MR arthrography and surgical correlation. Such variations in the LHBT can mimic tears of the tendon itself or the adjacent superior labrum both on MR arthrography and at surgery. MR arthrographic features are recognizable and allow for correct prospective diagnosis, possibly averting unnecessary surgery. Although further study is needed, patients with these anomalies may be at increased risk for developing shoulder instability.
