Scapula has three margins and angles and located posterolateral of thorax. One of the anatomical structures of scapula is suprascapular notch located medial to coracoid process base. Suprascapular notch can be seen in different shapes and depths. Suprascapular notch is surrounded by transverse scapular ligament which is a short and strong ligament. Suprascapular notch creates an osteofibrosis passage with this structure within suprascapular nerve passes. It has been reported that this osteofibrosis structure can intirely or partially ossify. All lesions of nerves occured in course as result of exposure to compression, tension and bending are called entrapment neuropathy. Like other peripheral nerves, suprascapular nerve can be exposed to compression while passing suprascapular notch. As a result of this compression suprascapular entrapment neuropathy may occur. There are direct trauma, repetitive microtrauma, neurit, progressive compressive lesions in suprascapular entrapment neuropathies etiology. A suprascapular notch taken foramen shape can be a predisposing factor to entrapment neuropathy. In the retrospective screening from Necmettin Erbakan University, Meram Medical Faculty, Department of Radiology archive, a male patient at age 68 with suprascapular notch variation has been detected. This patient’s right suprascapular notch had became foramen by an osseous bridge. Diameters of foramen has been measured as 5.27 mm transverse 6.48 mm vertical. We believe having detailed knowledge of suprascapular notch is significant as a possible course of back and shoulder pain is entrapment of suprascapular nerve in suprascapular notch causing nerve paralyses, and it will give a right direction to clinicians in surgical practices.

KEY WORDS: Suprascapular notch; Multidetector Computed Tomography; Variations.
