We present here a patient of congenital non-obstructive focal dilatation of intrahepatic biliary radicles (Caroli's disease). The peculiar configuration of dilated intrahepatic biliary channels with central portal vein radicles was picked up sonologically as the 'central dot' sign. Awareness of this sign allows an accurate diagnosis without resorting to more invasive and expensive investigations.
