The Portal Vein (PV) is formed by the selective involution of the vitelline veins. Any change in the anastomotic pattern of the vitelline veins during their development results in several PV variants. Knowledge on the normal anatomy and the portal vein variants is of great importance for liver surgeries and interventional procedures. We are reporting here the computed tomography features of an unusual variant of the portal vein in a patient with carcinoma of the gall bladder. In this patient, the main portal vein enters the right lobe of the liver and courses in to the left lobe, which gives only segmental branches along its course. As per our knowledge, only very few of such cases have been reported in the literature so far.
