Suprascapular nerve entrapment is an uncommon entity; it is usually missed as a differential diagnosis of shoulder pain, especially since the main presentation of this condition in patients is usually non-specific shoulder pain. It is often only considered when the patient presents with weakness and denervation of the supraspinatus and infraspinatus muscles. Diagnosis of spinoglenoid ganglion cysts is usually considered after other causes have been ruled out. They are usually detected on magnetic resonance imaging (MRI); however, this could be delayed and happens only after suprascapular nerve compression has already occurred and the patient's muscles have atrophied leading to limitations in their function. Treatment of spinoglenoid ganglion cysts should be tailored to each individual patient. Numerous treatment options are available and can range from conservative management to open decompression. The aim of our study was to highlight the clinical presentation of this condition by describing a case that we have diagnosed and managed at our center. We report a 29-year-old male who presented with dysfunctional left shoulder pain. The patient was diagnosed with a spinoglenoid ganglion cyst, which was treated successfully with open excision. The patient's condition improved following the procedure with a successful return to his daily activities.
