Postcoital hemoperitoneum without identifiable bleeding source: a case report.

Spontaneous intra-abdominal bleeding has been called abdominal apoplexy. It has been so named because its nature and spontaneity closely resemble those of its more common cerebral counterpart. The bleeding source commonly came from a ruptured branch of celiac axis or superior mesenteric artery. Rarely, hemoperitoneum occurs spontaneously post coitus without evident vaginal injury. There were only twelve cases reported in the medical literature to date. Nearly, all of them showed injury of pelvic organs including round or broad ligaments, ovarian cysts or adhesion bands. A case of massive hemoperitoneum after coitus, with no definite bleeding source, is reported.
