The trasscapular view shows flattening of posterolateral humeral head. Axial FS T1-weighted MR arthrograms demonstrated medial displacement of the labral ligamentous attachment and a Hill-Sachs fracture with subjacent bone marrow edema in the posterolateral humeral head. Oblique sagittal image shows inferior and medial shifting of the labroligamentous attachment on the glenoid. Differential Diagnosis: Bankart lesion Perthes lesion GLAD lesion Diagnosis: Anterior labral periosteal sleeve avulsion (ALPSA) and Hill-Sachs lesions in anterior shoulder dislocation Discussion: The ALPSA lesion is a tear of the anteroinferior labrum with associated capsuloperiosteal stripping. The torn labrum is rotated medially, and a small cleft or separation can be seen between the glenoid margin and labrum. The Bankart lesion is complete detachment of the labroligamentous complex. The Perthes lesion is a nondisplaced tear of the anteroinferior labrum that was attached by a linear structure with decreased signal intensity believed to be the intact medial periosteum. The GLAD lesion is a tear of the anteroinferior labrum with an attached fragment of articular cartilage but without associated capsuloperiosteal stripping. References: 1.
