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).

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. This variation can be characterised as 'type 2a' in accordance with the classification shown in Fig. 3 (type 2a).
(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.
