title: A large pseudolesion in the left lobe of the liver caused by inferior vena caval obstruction secondary to metastatic retroperitoneal lymphadenopathy.
abstract: A rare case with a large pseudolesion in the left lobe of the liver observed on early phase of incremental dynamic computed tomography (CT) caused by inferior vena caval obstruction is presented. Decreased portal perfusion due to increased volume of systemic venous inflow into the left lobe via paraumbilical venous system may be its underlying hemodynamic change. The etiology of this pseudolesion was successfully confirmed by conventional CT with intravenous contrast medium injection via superficial vein of lower extremity.
