Rotator Cuff Tears and Treatment Options

Shoulder MRI/Arthroscopy Correlations - Case 4: Paralabral Cyst Associated with Posterior Labral Tear

by Steven D. Levin, MD; Martin L. Lazarus, MD

In the fourth of an ongoing series of arthroscopy/MRI correlations case studies, Dr. Levin and Dr. Lazarus illustrate and compare the MRI and arthroscopic findings in a 34-year-old right-hand dominant male who lost control of a heavy cart, which pulled his arm back in an abducted, externally rotated position. Dr. Levin, Chief of the Division of Sports Medicine in Orthopaedic Surgery at NorthShore University Health System Medical Group, first discusses presentation and physical examination findings. Dr. Lazarus, Chief of the Section of Musculoskeletal Radiology at Northshore University Health System Medical Group, then assesses the findings on MRI, followed by Dr. Levins video narration of the arthroscopic examination and procedure. This case study includes an interactive imaging quiz.
