Ovarian abscess during pregnancy mimicking a leiomyoma of the uterus: a complication of transvaginal ultrasound-guided oocyte aspiration.

Abstract

Ovarian abscess is a serious complication that may occur after transvaginal oocyte aspiration for IVF. Symptoms may be very mild, late, or even absent. Mechanical obstruction of the pelvic inlet may be the only sign during pregnancy. Therefore, when a pelvic mass is discovered after transvaginal oocyte aspiration, the possibility of an ovarian abscess should be considered. Complications may occur when the diagnosis is missed or if the condition is misdiagnosed to be a leiomyoma instead of an ovarian abscess. This case demonstrates the necessity of careful and adequate abdominal and pelvic examination at the time of cesarean section, especially when a pelvic abnormality is already expected.
