Abstract

We describe two cases of thrombosed extrahepatic portal vein aneurysms diagnosed by sonography, computed tomography, and magnetic resonance imaging. Portal vein aneurysm is a rare clinical entity that has been described as a focal dilatation that can affect intra- and extrahepatic portal branches. Although usually asymptomatic, thrombosis can lead to portal hypertension. Clinical and imaging characteristics are discussed, in addition to a review of the literature.

摘要

我们描述了两例通过超声、计算机断层扫描和磁共振成像诊断出的肝外门静脉瘤血栓形成病例。门静脉瘤是一种罕见的临床病症，被描述为可影响肝内和肝外门静脉分支的局灶性扩张。虽然通常无症状，但血栓形成可导致门静脉高压。除了文献综述外，还讨论了其临床和影像学特征。
