Congenital tracheobiliary fistula (CTBF) is a rare malformation. So far 24 cases have been reported in the English language literature. The imaging techniques used in diagnosis have been bronchography, fistulography, cholangiography, hepatobiliary nuclear imaging and MRI. We report a newborn patient who presented with right lung consolidation and biliptysis. The radiographic diagnosis of tracheobiliary fistula was made on multidetector CT scan of the chest and abdomen. Multiple 3-D volume-rendered reformations were performed. An abnormal air-filled tract was seen connecting the posteroinferior aspect of the carina and left biliary system, which was successfully treated surgically.
