Aberrant gastric venous inflow to the left lobe of the liver parenchyma adjacent to the falciform ligament.

Direct inflow of the aberrant right gastric vein independent of the portal venous system to the liver parenchyma is a well known cause of non-tumorous abnormalities on CT angiography. However, there have been no previous reports of aberrant gastric venous drainage as the cause of non-tumorous abnormalities in the left lobe of the liver parenchyma adjacent to the falciform ligament on CT angiography. We present a case of direct inflow of an aberrant gastric vein to this region of the liver, which influenced the non-tumorous enhancement shown by CT hepatic arteriography.
