Arterial aneurysms are more common than visceral venous aneurysms. Portal vein aneurysms being the most common type of visceral venous aneurysms. Here, we present an 18-year-old young woman with thalassaemia major, who presented with headache, palpitation, shortness of breath and a recent increase in blood transfusion rate. On clinical examination, she had hepatosplenomegaly. Ultrasonography revealed hepatosplenomegaly with fusiform dilatation of extrahepatic portal vein, which was confirmed to be portal vein aneurysm on contrast enhanced CT. Though portal vein aneurysms were previously thought to be rare, recently they are increasingly diagnosed with the use of cross-sectional imaging. Recognition of this finding can help to avoid potential confusion with other periportal cystic masses of different aetiologies, especially on sonography.
动脉性动脉瘤比内脏静脉性动脉瘤更常见。门静脉瘤是内脏静脉性动脉瘤中最常见的类型。在此，我们报告一名18岁的重型地中海贫血年轻女性，她出现头痛、心悸、呼吸急促以及近期输血率增加。临床检查时，她有肝脾肿大。超声检查显示肝脾肿大，肝外门静脉呈梭形扩张，增强CT证实为门静脉瘤。尽管门静脉瘤以前被认为很罕见，但近来随着横断面成像技术的应用，其诊断越来越多。认识到这一发现有助于避免与其他病因不同的肝门周围囊性肿物产生潜在混淆，尤其是在超声检查时。
