Abstract

Introduction: Aneurysms of the superior mesenteric branch arteries are rare. The natural history is unknown and there is no consensus on management. We report a case of right colic artery aneurysm rupture. Report: A 70-year-old male presented with a two week history of right flank pain and syncope. On admission he was hypotensive, but responded to fluid resuscitation and was discharged after a two day observation period. He attended his family doctor with bruising in the right groin and abdominal distension. CT confirmed a 2 cm aneurysm arising from a branch of the right colic artery with a large associated haematoma and active extravasation. Discussion: Mesenteric artery aneurysms are rare and often misdiagnosed. Management options include embolisation or open surgery. The mesentery can act to tamponade in some cases resulting in a delayed diagnosis of rupture.
