MR arthrogram left shoulder
On the coronal images, the inferior glenohumeral ligament is torn at the glenoid insertion with extra-articular contrast leakage.
The inferior glenohumeral ligament is lax and edematous and it has a “J” conﬁguration in the opposite direction of a HAGL lesion.
It can lead to traumatic anterior shoulder instability.
GAGL most often results from anterior shoulder dislocation due to forced hyperabduction and external rotation of the arm.
