Aneurysmal dilatation of the portal vein: a rare cause of portal hypertension.
Aneurysmal dilatation of the portal vein (ADPV) is a rare cause of portal hypertension. We described a case of ADPV in a female patient who presented with ascites. Imaging studies revealed tortuosity and dilatation of the main portal vein with turbulent flow. Endoscopy revealed oesophageal varices. A liver biopsy showed no abnormalities in liver histology. This is the first case of ascites as a complication of ADPV in the absence of liver cirrhosis, arteriovenous fistula or documented portal vein thrombosis. Hyperdynamic circulation and increased portal vein flow could be implicated in the pathogenesis of ascites in this setting.
