There was transient hold-up of contrast caused by extrinsic compression of the first part of the duodenum by a 2cm, rim-calcified mass. The subsequent CT scan showed a heavily calcified common hepatic artery aneurysm (HAA) which indented the pylorus and was the cause of her gastric outlet obstruction.<\/p>\n<p>&nbsp;<\/p>\n<p>HAA are rare and asymptomatic in 75% of patients. Unfortunately, around 15% of patients present with a rupture.[1] In symptomatic patients, epigastric pain and jaundice are the most common features.[2] HAA are more frequent in males, associated with hypertension, smoking and alcohol intake, malignancy[1] and previous biliary surgery.[2] When suspected CT angiography can characterise the lesion and inform future treatment decisions which can include stenting, embolisation, ligation and vascular reconstruction.[2]<\/p>\n<p>&nbsp;<\/p>\n<p>We could not find any other reports of HAA causing gastric outlet obstruction, although a case involving a pancreaticoduodenal artery aneurysm has been described.[3] Although rare, visceral artery aneurysms should be recognised in the aetiology of gastric outlet obstruction. Our patient\u2019s symptoms have eased with conservative management including dietary modification and proton pump inhibitor therapy.
