A rare surgical emergency during pregnancy: a case report.

Acute pelvic pain during pregnancy often presents a diagnostic challenge. We report a case of adnexal torsion occurring in the third trimester of pregnancy in order to highlight this diagnosis, for which only early management can prevent irreversible ischemic damage that may compromise future fertility. The patient was a nulliparous woman at 30 weeks of amenorrhea who initially presented with symptoms suggestive of appendicitis. Through a McBurney incision, surgical exploration revealed a necrotic right ovary associated with reactive appendicitis. An oophorectomy and appendectomy were performed. The postoperative course was uneventful.
