A, B Coronal reconstruction of CECT scan showing enlargement of portal vein and superior and inferior mesenteric veins (A, arrow) with no contrast enhancement due to acute thrombosis.. Thickening and absence of enhancement of bowel walls due to venous ischemia (dotted arrow), with mesenteric edema. Presence of abundant free peritoneal fluid, mostly perihepatic (A-B, asterisk).

Hence a CECT was performed and revealed a massive thrombosis of right intrahepatic portal branches, portal vein, superior and inferior mesenteric veins with associated extended acute venous ischemia of the small bowel, colonic wall thickening with normal contrast enhancement and abundant peritoneal effusion (Fig. 1).
A, B, C Comparison between initial (A, B) and follow-up (C) CECT examinations.. Axial views showing acute thrombosis of the main intrahepatic branches of portal vein (A, arrow) and of the extrahepatic portal vein (B, dotted arrow).. Follow-up axial image demonstrating complete resolution of the thrombosis (C, arrowhead) and of the ascites.
