"The tubercle of Assaki is a small (about 6 mm of average diameter 2) thickening of subchondral bone of the glenoid fossa, which is overlaid by the area of thinned cartilage known as glenoid bare spot 2."
"Like the glenoid bare spot, it is best appreciated using fluid-sensitive sequences like T2 FSE in coronal and axial planes and it should not be mistaken for a cartilage defect 1."
