Massive hemoperitoneum following rupture of hepatic metastases from unsuspected choriocarcinoma

Spontaneous massive hemoperitoneum in a reproductive-aged woman is usually associated with ectopic pregnancy. An unusual cause of intraperitoneal hemorrhage is presented: spontaneous rupture of hepatic metastases from unsuspected choriocarcinoma in a 29-year-old woman 4 weeks postpartum. Although choriocarcinoma is known to have the potential for subsequent hemorrhage of secondary sites, massive hemoperitoneum due to rupture of hepatic metastases is rare. In this case report, the presentation, prognosis groups, and treatment modalities are presented.
