Objective: The purpose of this article is to review frequently encountered pitfalls as they pertain to normal and variant anatomy of the shoulder, including the rotator cuff and rotator cable, blood vessels, glenoid labrum, and the glenohumeral ligaments., Conclusion: MRI is the preferred method for evaluating internal derangement of the shoulder. Radiologists interpreting MR images should have a detailed understanding of pertinent anatomy and knowledge of common and uncommon pitfalls to avoid during image interpretation.

Objective: The purpose of this article is to review frequently encountered pitfalls as they pertain to the biceps tendon, bursae and cysts around the shoulder, incidental findings, postsurgical findings, and frequently encountered imaging artifacts., Conclusion: Imaging pitfalls in and around the shoulder are not limited to normal anatomy and anatomic variants. Radiologists must be cognizant of the vast variability of structures in the shoulder and of the incidental and postsurgical findings and artifacts affecting them.

Objective: The objectives of this article are to discuss the 10 distinct patterns of superior labral anteroposterior (SLAP) tears to facilitate adequate diagnosis and treatment. Correlations with clinical presentation, mechanism of injury, and treatment will enhance understanding., Conclusion: Imaging plays an important role in the diagnosis of SLAP tears. Knowledge of glenolabral anatomy, related structures and variants, proper imaging techniques, and a systematic approach to MRI interpretation is important in the diagnosis and treatment planning of the 10 types of SLAP lesions. Arthroscopy offers a means for definitive diagnosis.

Objective: The objectives of this article are to provide a pictorial review of labral anatomy and physiology, with particular attention to commonly seen anatomic variants and pitfalls, and to present standard imaging techniques and approaches to MRI interpretation to facilitate diagnosis and treatment of superior labral anteroposterior (SLAP) lesions., Conclusion: Imaging plays an important role in the diagnosis of SLAP tears. Knowledge of glenolabral anatomy, related structures and variants, proper imaging techniques, and a systematic approach to MRI interpretation is important in the diagnosis and treatment planning of the 10 types of SLAP lesions. Arthroscopy offers a means for definitive diagnosis.
