Spinoglenoid notch syndrome

Spinoglenoid notch syndrome is caused by compression of suprascapular nerve due to a ganglion cyst at spinoglenoid notch resulting in shoulder pain and posterior shoulder tenderness.

Clinical presentation

On clinical examination, there is posterior shoulder tenderness, discomfort in external rotation and abduction. Weakness and wasting of supraspinatus tendon is also observed.

Radiographic features

MR

A ganglion cyst elicits hyperintense signal on T2 and STIR images. Adjacent muscle changes are often visible: edema in acute changes and atrophy or fatty infiltration in chronic changes.

Treatment and prognosis

Ultrasound-guided aspiration of cyst followed by physical therapy of shoulder joint is the most popular approach. Arthroscopic decompression of the ganglion, and open excision of the cyst are the other available surgical options.

Differential diagnosis

It may be mistaken for cervical spondylosis or rotator cuff injury.
