The abdominal multidetector computed tomography (Figure 1) revealed a heterogeneously enhancing mass lesion of size 10 x 10 x 13 cm involving segments V, VI, VII, and VIII of the right hemiliver with early arterial enhancement, persisting in subsequent phases, with prominent feeding right hepatic artery and right portal vein thrombosis.
Intraoperative pictures showing (A) prominent right hepatic artery with collaterals and (B) demarcated right hemiliver after inflow control.
