Hemorrhagic corpus luteum cyst torsion in term pregnancy: a case report

Hemoperitoneum during pregnancy resulting from spontaneous rupture of adnexal torsion is a rare cause of fetal and maternal death. Presenting symptoms include severe abdominal pain, followed rapidly by maternal shock and fetal distress. It is hard to localize the adnexae in advanced pregnancy. Here, we present a case of spontaneous rupture of hemorrhagic corpus luteum cyst torsion that had not been previously diagnosed by ultrasound during term pregnancy. The patient was sent to our emergency room for sudden onset of severe low abdominal pain. Treatment consists of maintenance of adequate circulating intravascular volume and rapid surgical intervention. Preoperative diagnosis of adnexal torsion during term pregnancy is very difficult, although it is always identified during surgery.
