Hemoperitoneum from corpus luteum cyst rupture in pregnancy of unknown location

Hemoperitoneum from corpus luteum cyst rupture in pregnancy of unknown location

The presence of corpus luteum cyst rupture resulting in hemoperitoneum together with a diagnosis of pregnancy at unknown location is rare and challenging for the gynecologist. A 29-year-old primipara woman presented with abdominal pain. A urine pregnancy test was positive. Ultrasonography revealed hemoperitoneum, but there was no sign of any intrauterine pregnancy. On abdominal exploration, there was a massive hemorrhage with a ruptured corpus luteum on the right ovary. The diagnosis and management difficulty of corpus luteum cyst rupture with a concomitant positive pregnancy test but without exact confirmation of pregnancy location is discussed.
