A) Definition:
HAGL means humeral avulsion of inferior gleno- humeral ligament.
GAGL means glenoid avulsion of inferior gleno- humeral ligament.
GAGL lesion can occurs with Bankart lesion while HAGL lesion occurs separately.
B) MR signs:
A 3D representation of the inferior glenohumeral ligament demonstrates the sling-like anatomy of the anterior and posterior bands of the ligament.
Image reference
A tear of the inferior glenohumeral ligament (arrow) at its humeral attachment is seen in this depiction of a HAGL lesion.

Image reference:
GAGL lesion. A 35-year-old male presented with recurrent anterior shoulder dislocation. Coronal STIR MRI image shows that the antero-inferior labrum is intact (small arrow) but the anterior band of the IGHL is avulsed at its glenoid attachment (long arrow). Also note the hyperintensity involving the supraspinatus tendon (arrowhead) and the fluid in the subdeltoid bursa (block arrow). The patient also had a full-thickness supraspinatus tendon tear
