An Often Missed Finding in Ultrasonographic Shoulder Examination

A standardized US evaluation[1] of both shoulders was conducted with an US machine (Samsung RS80A, Samsung Medison Co., Ltd., Seoul, Korea) equipped with a linear LA4‐18B probe. The long head of biceps (LHB) tendon was within normal limits, without any effusion, but there was, just superficial to it, an oval-shaped fibrillar structure seen coursing from the rotator cuff near the rotator interval all the way down to the pectoralis major tendon at the level of the myotendinous junction of the LHB [Figures 1-4]. This structure was moderately painful with sonopalpation.
