Arthroscopic Treatment of a Ganglion Cyst Originating from the Transverse Acetabular Ligament in the Hip Joint A Case Report

INTRODUCTION: Intra-articular ganglion in the hip joint is rare. Here, we present a case of ganglion cyst originating from the transverse acetabular ligament (TAL) in the hip joint treated by arthroscopic surgery. CASE REPORT: A 48-year-old man presented with the right groin pain after activity. A cystic lesion was found on magnetic resonance imaging. Under arthroscopic view, a cystic mass was identified between the TAL and ligamentum teres that discharged yellowish viscous liquid after puncture. The remaining lesion was resected in its entirety. A diagnosis of ganglion cyst was consistent with the histological findings. The patient has had no recurrence on magnetic resonance imaging as of 6 years postoperatively and had no complaints at the 6-year follow-up visit. CONCLUSION: Arthroscopic resection is useful for an intra-articular ganglion cyst in the hip joint.
