Abstract

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.
