BACKGROUND
Portal vein aneurysm (PVA) is an uncommon vascular dilatation, showing no clear trend in sex or age predominance. Due to the low number of published cases and the lack of management guidelines, treatment of this condition remains a clinical challenge.
CASE SUMMARY
We present three cases of asymptomatic PVA; the first and second involve an extrahepatic manifestation, of 48 mm and 42.3 mm diameter respectively, and the third involves an intrahepatic PVA of 27 mm. All were diagnosed incidentally during routine check-up, upon ultrasonography scan. Since all patients were asymptomatic, a conservative treatment strategy was chosen. Follow-up imaging demonstrated no progression in the aneurysm dimension for any case.
CONCLUSION
As PVA remains asymptomatic in many cases, recognition of its imaging features is key to favourable outcomes.
背景
门静脉瘤（PVA）是一种罕见的血管扩张，在性别或年龄优势方面没有明显趋势。由于已发表的病例数量较少且缺乏管理指南，这种疾病的治疗仍然是一项临床挑战。
病例总结
我们报告三例无症状门静脉瘤；第一例和第二例为肝外表现，直径分别为48毫米和42.3毫米，第三例为肝内门静脉瘤，直径为27毫米。所有病例均在常规检查的超声扫描中偶然诊断出来。由于所有患者均无症状，因此选择了保守治疗策略。随访影像学检查显示，所有病例的动脉瘤大小均无进展。
结论
由于许多情况下门静脉瘤仍无症状，识别其影像学特征是取得良好治疗效果的关键。
