Scintigraphic detection of hemobilia and hemoperitoneum secondary to rupture of hepatic artery aneurysm.

Hemobilia frequently presents with variable gastrointestinal (GI) tract bleeding, biliary colic, and jaundice and should be considered in the differential diagnosis of obscure blood loss from the GI tract. Reported here is a case of a ruptured hepatic artery aneurysm that was diagnosed using Tc-99m labeled red blood cells. Delayed images demonstrated both hemobilia and free intraperitoneal hemorrhage, which were subsequently confirmed by computed tomography and laparotomy. A similar case has not been previously reported in the scintigraphic literature.
