Rarely, corpus luteum hemorrhage may produce a life threatening emergency or may be fetal if not diagnosed or treated. 15 cases of ruptured corpusluteum cysts in the duration of three years presented at PIMS (pacific institute of medical sciences) Umarda, Udaipur, Rajasthan. The presentation was mimicking ruptured ectopic pregnancy and in three cases (20%) the patient just passed out suddenly while at home or at market place They were brought to the hospital in unconscious state. In other cases (80%) the presentation was less dramatic and chronic. There had been no history of amenorrhoea nausea and vomiting. Urine pregnancy test was negative. Refractory hypotension could not be improved by intravenous therapy and were referred to gynaecologist. Ultrasonography of abdomen showed fluid and clots in pouch of douglas and ascites. Keeping ruptured ectopic in mind laparotomy was performed which revealed haemoperitoneum. However both side fallopian tubes were intact. Ovary on one side revealed ruptured corpus luteum cyst with fresh oozing from the site of rupture. Ovary was repaired and haemostasisensured and the patients made an uneventful recovery. To Conclude Ruptured corpus luteum cyst should be kept in mind while treating gynae emergencies with haemoperitoneum and acute abdominal pain.
