"A superior sublabral sulcus is a frequent finding on MRI and can be found in more than 70% of cases 2,3. It features a similar appearance and needs to be differentiated from sublabral foramen and from type II SLAP lesion 5. The latter is usually characterised by irregular contours that can extend posteriorly to the biceps tendon anchor 2 or laterally into the substance of the glenoid labrum 1."
