• Segmental arterial mediolysis
• Hepatic aneurysm
• Hepatic artery
• Rupture
• Spontaneous intra-abdominal hemorrhage

This article reports a patient with intra-abdominal hemorrhage secondary to a rare vascular disease, segmental arterial mediolysis (SAM). The patient was a 68-year-old male who presented with chilling and severe abdominal pain. Abdominal computed tomography results suggested the presence of an intra-abdominal hemorrhage. Although visceral angiography illustrated multiple aneurysms in the branches of the hepatic artery, active bleeding was not evident. Conservative therapy including transfusion was performed, and re-angiography revealed the disappearance of multiple hepatic arterial aneurysms 8 months later. This is the first case of intra-abdominal hemorrhage related to SAM of the hepatic artery in which natural history of SAM was seen.
