Case report

Pseudolesion in segment IV of the liver adjacent to the falciform ligament caused by drainage of the paraumbilical vein: demonstration by power Doppler ultrasound

A case of a pseudolesion in segment IV of the liver, adjacent to the falciform ligament, was observed on conventional CT and CT during arterial portography. The pseudolesion was caused by drainage of the paraumbilical vein. Power Doppler ultrasound was helpful in recognizing this pseudolesion by depicting that the paraumbilical vein was connected to vessels in this area. Although the direction of flow could not be determined, power Doppler ultrasound is a useful method for confirming non-invasively the aetiology of pseudolesions in this area.
