Pelvic abscess after ultrasound-guided aspiration of endometrioma: a case report.

A 31-year-old female with four years of infertility due to endometriosis and severe pelvic adhesions underwent transvaginal ultrasound-guided aspiration of an ovarian endometrioma before ovulation induction for in vitro fertilization (IVF) and embryo transfer. Seven days following the aspiration, the patient developed acute abdominal pain; diagnostic laparoscopy was performed at a local medical center, revealing a right tubo-ovarian abscess. Exploratory laparotomy ensued and right salpingo-oophorectomy was performed. A combination regimen of three antibiotics was administered and the patient was transferred to the intensive care unit of the Cathay General Hospital two days after surgery for further care. Her postoperative condition was uneventful and she recovered quickly. The patient then continued with further IVF treatment.
