The portal venous system is absent. There is a large caliber, vertically oriented vein along the left hemiabdomen (giant inferior mesenteric vein) with superior mesenteric and splenic venous tributaries superiorly and draining inferiorly into both internal iliac veins. The tributaries of the mesenteric veins are engorged. Mesenteric phleboliths are also seen. These findings are compatible with Abernethy malformation.
Probable hepatic segment V hemangioma and right simple renal cyst are also demonstrated.
