magnetic resonance (MR) imaging and MR arthrography are frequently utilized in
the evaluation of shoulder pain and instability. The clinical scenario and
imaging findings may be confusing to clinicians and radiologists and may
present diagnostic challenges for those involved in evaluating and treating
shoulder pathology. Often rotator cuff and labral abnormalities may be
coexistent, clinical manifestations of denervation syndromes may be confusing
to clinicians, and normal anatomic variations, imaging pitfalls, and various
artifacts may cause dilemmas for the radiologist. This article will review the
most frequently encountered mimickers and pitfalls of MR imaging of the
