Hepatic artery aneurysm (HAA) is a rare, yet clinically important, condition. While the causes of HAA are poorly understood, it is estimated that mortality following spontaneous rupture is as high as 40%. We discuss the case of a 77-year-old man who presented to our hospital due to a 10 mm pulmonary lesion in the left lower lung lobe, which was identified by a computed tomography scan of the lung at another institution. An examination with 18F-fluorodeoxyglucose positron emission tomography/computed tomography was performed in our department, but no significant uptake of 18F-fluorodeoxyglucose was found in the lung, and HAA was diagnosed only incidentally. A magnetic resonance imaging angiography supported the differential diagnosis of HAA, and the aneurysm was confirmed by targeted angiography. It was located in the common hepatic artery and was coiled during an intervention session. HAA accounts for 20% of all visceral aneurysms and, with a poorly understood natural history, is difficult to diagnose clinically, but early detection and treatment of HAA can improve prognosis.
肝动脉动脉瘤（HAA）是一种罕见但在临床上很重要的病症。虽然HAA的病因尚不清楚，但据估计，自发破裂后的死亡率高达40%。我们讨论了一名77岁男性的病例，他因左下肺叶一个10毫米的肺部病变到我院就诊，该病变是在另一家机构进行肺部计算机断层扫描时发现的。我院进行了18F-氟脱氧葡萄糖正电子发射断层扫描/计算机断层扫描检查，但肺部未发现18F-氟脱氧葡萄糖有明显摄取，HAA只是偶然被诊断出来。磁共振成像血管造影支持HAA的鉴别诊断，通过靶向血管造影证实了动脉瘤的存在。它位于肝总动脉，并在一次介入手术中进行了栓塞治疗。HAA占所有内脏动脉瘤的20%，其自然病史尚不清楚，临床上难以诊断，但早期发现和治疗HAA可改善预后。
