Abstract

We present a case of left suprascapular nerve palsy in a 39- year-old female secondary to compression from a large ganglion cyst. She presented with a two month history of left posterior shoulder pain which affected her work and disturbed her sleep. Clinical examination revealed a positive O'Brien's test. Supraspinatus and infraspinatus strength was mildly weakened. A magnetic resonance imaging (MRI) scan of the left shoulder revealed a superior labral anterior to posterior (SLAP) lesion with a large supraglenoid labral cyst extending posteriorly to the spinoglenoid notch, resulting in compression of the suprascapular nerve. Arthroscopy revealed the SLAP lesion with a haemorrhagic labral cyst at the posterosuperior aspect. Arthroscopic decompression of the cyst and SLAP repair with two suture anchors was performed. At 22 months postoperative follow-up, the patient's left shoulder remained asymptomatic with full range of motion and full strength.

Highlights

Shoulder pain is among the most common musculoskeletal complaints in the general population
This condition is often not diagnosed until a magnetic resonance imaging (MRI) scan is performed on the patient who fails to respond to therapy
An MRI scan of the left shoulder confirmed the presence of a large supraglenoid labral cyst extending posteriorly to the spinoglenoid notch, with a suspected superior labral anterior to posterior (SLAP) lesion (Figure 1)

Summary

Introduction

Shoulder pain is among the most common musculoskeletal complaints in the general population. Suprascapular nerve compression may be the cause of such shoulder pain or weakness. She had pain especially during overhead position and internal rotation of the left shoulder. She complained of mild weakness of her left shoulder.
