Abstract

Introduction: Our case was incidentally diagnosed large aneurysm of the main portal vein. The incidence of intrahepatic and extrahepatic portal vein aneurysms (PVAs) is not clear. Portal vein aneurysm usually occurs at the junction of the superior mesenteric vein and splenic veins or at the hepatic hilus at the bifurcation of the right and left portal veins [1]. Case Report: Color Doppler and contrast-enhanced dynamic computed tomography scan and computed tomography angiography clearly showed a well-circumscribed, 44x34 mm intrahepatic portal vein aneurysm. Conclusion: The aim of this study is to evaluate the imaging features of portal vein aneurysm.

Summary

Introduction

Our case was incidentally diagnosed large aneurysm of the main portal vein. The incidence of intrahepatic and extrahepatic portal vein aneurysms (PVAs) is not clear. Case Report: Color Doppler and contrast-enhanced dynamic computed tomography scan and computed tomography angiography clearly showed a well-circumscribed, 44x34 mm intrahepatic portal vein aneurysm. The laboratory tests of the patient were normal She was evaluated with ultrasonography and intrahepatic cystic lesion was detected. On computed tomography (CT) scan, portal vein aneurysm was seen as a well-circumscribed enhanced mass communicating with the portal vein (Figure 3A–B). Three-dimensional and volume rendered contrast-enhanced dynamic computed tomography and angiography images clearly showed aneurysmal dilatation of the umbilical portion of the portal vein and the relation between the aneurysm and portal vein branches (Figure 4)
