[Acute abdomen due to ovarian hemorrhage].

Massive intraperitoneal hemorrhage from ruptured ovaries may occur not only during antikoagulant therapy. In 20 out of total 24 cases of the Universities-Frauenklinik Jena the origin of the hemorrhage was a ruptured corpus luteum, only in three cases an ovarian follicle and in one case a luteinic cyst. Differential diagnosis to ectopic pregnancy is nearly impossible. Explorative laparotomy has to be performed to assure the diagnosis.
