Hip arthroscopy as a treatment for obturator neuropathy secondary to intra-pelvic ganglion: a case report

The most common types of cystic lesions around the hip joint are synovial or ganglion cysts. In rare cases, the cysts can compress adjacent structures and cause symptoms to arise. Obturator neuropathy secondary to a hip ganglion cyst is a rare phenomenon, with scarce reports on suggested treatment options. Hip arthroscopy is a potential minimally invasive treatment that has yet to be described in such cases. We present a 52-year-old male suffering from obturator neuropathy caused by an intra-pelvic ganglion cyst arising from the hip joint. Hip arthroscopy was performed for decompression of the cyst and dilation of the stalk opening. Six-month post-operative follow-up showed resolution of symptoms and complete elimination of the cyst on magnetic resonance imaging.
