RESUMO
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.
RESUMO
PURPOSE: There are many known treatment modalities for spinoglenoid ganglion cyst accompanied by suprascapular nerve palsy. However, to the author's knowledge, there is no report on the follow-up outcomes focused on remnant cysts. MATERIALS AND METHODS: Six (n=6) patients with spinoglenoid ganglion cyst accompanied by suprascapular nerve palsy, with a mean follow-up of 15 months (12-23months) following arthroscopic cyst decompression and superior labral repair, were enrolled. Residual cyst was investigated by ultrasonography and MRI. RESULTS: Immediate postoperative ultrasonography revealed complete remission of ganglion cyst in one patient and reduced ganglion cyst size in five patients. Three-month follow-up ultrasonography showed spontaneous complete remission of the residual cysts in all patients. No recurrence on MRI was seen at one-year follow-up. CONCLUSION: Residual spinoglenoid ganglion cyst remaining after arthroscopic decompression and superior labral repair tends to resolve spontaneously within 3 months of surgery.
