Tubo-ovarian abscess mimicking ovarian tumor in a sexually inactive girl.

Tubo-ovarian abscess is a serious complication of pelvic inflammatory disease rarely seen in sexually inactive girls. Early diagnosis and treatment are essential to prevent further sequela including infertility, ectopic pregnancy, and chronic pelvic pain. We present a case of 19-year-old sexually inactive girl who presented with abdominal pain and pelvic mass resembling ovarian tumor. Unilateral tubo-ovarian abscess with extensive bowel adhesions was determined at laparotomy. Drainage of the abscess and postoperative antibiotic therapy cured the patient.
