Background:
Hemoperitoneum resulting from spontaneous rupture of the uterine vessels in pregnancy is rare and associated with high maternal and fetal mortality.
Case:
A woman presented with acute abdominal pain and hypovolemic shock at 20 weeks of gestation. Immediate laparotomy revealed massive hemoperitoneum resulting from spontaneous rupture of the left uterine vessels associated with a left adnexal mass consisting of decidualized endometriosis. The fetus was delivered by hysterotomy, hemostasis was achieved, and the woman made a good recovery.
Conclusion:
We report a case of hemoperitoneum in pregnancy that resulted from spontaneous rupture of the uterine vessels associated with decidualized endometriosis.
