The submitted case-history deals with a successfully diagnosed and treated case of post-traumatic hemobilia in a 13-year-old girl. Hemobilia was manifested clinically by the typical Sandblom triad of symptoms. It was due to a pseudoaneurysm of the peripheral arteriole of the hepatic artery diagnosed by selective liver angiography. In treatment selective intraarterial embolization of the supplying artery proved useful.
