case_images: Caucasian male was diagnosed with obstructive jaundice due to pancreatic duct adenocarcinoma. Computer tomography (CT) and magnetic resonance imaging (Figs 1 and 2) revealed a resectable tumor of the head of the pancreas, a duplicated IVC and a PV trifurcation. The left IVC formed exactly like the right one while draining to the left renal vein (Fig. 1).
case_images: (a) CT with contrast demonstrating the trifurcated portal vein (arrow); (b) gross appearance of the duplicated IVC intraoperatively (arrow).

Computer tomography (CT) and magnetic resonance imaging (Figs 1 and 2) revealed a resectable tumor of the head of the pancreas, a duplicated IVC and a PV trifurcation. This variation can be characterised as 'type 2a' in accordance with the classification shown in Fig. 3 (type 2a).
case_images: (a) Classification of IVC abnormalities; (b) variations of the branching of portal vein. MPV: main portal vein, RPV: right portal vein, LPV: left portal vein, RAPV: right anterior portal vein, RPPV; right posterior portal vein.
