Endometriosis and ovarian cyst misconceived as a failed back surgery syndrome: A case report

ABSTRACT

A 26-year old woman visited our pain clinic with sudden severe low back pain. She was treated for back pain by laminectomy and discectomy 8 years ago. Despite managements by analgesics and nerve block series, her symptoms were improved only shortly every time. She referred to a gynecologist due to vaginal bleeding, and endometriosis and ovarian cyst was found. Her symptoms were relieved by laparoscopic oophorectomy. Endometriosis and ovarian cyst are common gynecological diseases associated with low back pain. The incidence and prevalence of endometriosis are also highest in the same age range as that of people with nonspecific low back pain. We present a case of endometriosis and ovarian cyst manifested as nonspecific low back pain in the patient with a history of back surgery.
