Summary:

• Radiopaedia case ID: 42006
• Image ID: 18913744
• Image stack position: 7/9
• Plane projection: Frontal
• Aux modality: Superior mesenteric artery
• Study findings: Catheter angiography confirms the absence of the portal vein.  The superior mesenteric and splenic veins drain into a markedly dilated inferior mesenteric vein, which drains inferiorly into both internal iliac veins then into the common iliac veins and inferior vena cava.
• Modality: DSA (angiography)
• System: Vascular
• Findings: 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.
