Summary:

Description	Radiopaedia case ID: 34195 Image ID: 10933820 Image stack position: 3/5 Plane projection: Coronal Aux modality: T1 fat sat Study description: MR arthrogram of shoulder Study findings: Arthrographic MRI delineates the thin flimsy diminutive labrum, the thickened anterior capsule, and the large pouch of sleeve periosteum of anterior glenoid. The anteroinferior labrum from 2-6 o'clock position is almost completely medially dispaced, likely consequence to repeated trauma. The medial avulsion of the labrum is compatible with an ALPSA lesion (anterior labroligamentous periosteal sleeve avulsion; a.k.a. "medialized Bankart"). A SLAP 2 tear not reaching the biceps anchor complex is seen with evidence of avulsion of the glenoid attachment of inferior glenohumeral ligament (GAHL). These findings were not conspicuous on the non-arthrographic MRI. Modality: MRI System: Musculoskeletal Findings: Non-arthrographic MRI demonstrates anterior labral tear with a fluid cleft along the undersurface of labrum and the glenoid rim, suggesting a Perthes lesion (a non-osseous Bankart variant). A doubtful SLAP tear is also seen.
