Portal vein aneurysms are extremely rare and intrahepatic variety is the rarest. It is often an incidental, asymptomatic finding or may be associated with portal hypertension. Recognition of this finding can help to avoid potential confusion with abdominal masses of other aetiologies. In this report, we present a case of large intrahepatic portal vein aneurysm measuring approximately 7.7x6.4 cm. till date this is the largest intrahepatic portal vein aneurysm ever reported. KEYWORDS: Aneurysm, intrahepatic portal vein. CASE REPORT:A 25 years female with history of chronic vague abdominal discomfort was presented to the gastroenterology OPD. Per abdominal examination showed evidence of splenomegaly. There was no previous history of any surgical intervention or abdominal trauma. Liver function test showed elevation of hepatic enzymes. Complete haemogram and renal function test were within normal limits. She was advised a multiphasic CT abdomen to exclude any other abdominal pathologies. Multiphasic MDCT abdomen revealed a hypo dense lesion measuring approx 7.7cm x 6.4cm in size predominantly occupying the left lobe of the liver.No enhancement of the lesion is seen in the arterial phase. The lesion showed homogenous enhancement in the portal venous phase with branches of portal vein merging with the lesion suggesting portal venous origin of the lesion. The intrahepatic portal vein branches were otherwise ectatic. The main portal vein was also dilated and measures 18.5 mm near the splenoportal confluence. No thrombus is seen in the splenoportal axis. There was volume redistribution in the liver with enlargement of the left lobe and atrophy of the right lobe. No other focal lesion in the liver was seen. The paraumbilical vein was re canalised.The intrahepatic bile ducts, CHD, CBD and intrahepatic veins were unremarkable. The spleen was grossly enlarged. The splenic vein was also dilated and measures approx 16.6 mm. Superior mesenteric vein was normal. There was mild ascites. Pancreas was normal in size, shape and attenuation. No lymphadenopathy or any other abdominal pathology was seen. Constellation of findings suggested a saccular intrahepatic portal venous aneurysm with features of portal hypertension. DISCUSSION:Aneurysms of the portal vein is extremely rare and represent only 3% of all aneurysms of the venous system. 1 Barzilai and Kleckner 2 were the first to report a portal vein aneurysm, in 1956. The authors described the necropsy of a cirrhotic patient with a portal vein aneurysm and thrombus that ruptured into the biliary system. 2 Portal vein aneurysms are defined as focal dilatation of portal venous system, either extrahepatic or intrahepatic, extrahepatic being more common. Though exact mechanism is unknown, various etiologies ranging from congenitally defective regression of right primitive

Portal vein aneurysm is a relatively rare vascular anomaly whose cause and clinical manifestation have not yet been clarifi ed. Older publications emphasize its close relationship with portal hypertension and recommend intense treatment to prevent rupture or thrombus formation. 1-3 However, recent publications indicate that this relationship is doubtful and that occurrence of such serious complications is very rare. 4,5 Thus, the actual consensus is that when detecting an asymptomatic portal vein aneurysm, follow-up observation by color Doppler US is considered to be suffi cient. 4,5 Strictly speaking, the precise defi nition of portal vein aneurysm is sometimes diffi cult or ambiguous, but when US shows a marked segmental dilatation (3 cm) of the portal vein, as in our case, the diagnosis is thought to be appropriate.In the past, the diagnosis was established by portography; however, color Doppler US has been considered the most accurate tool, and clinicians now believe that fi nal
