The use of technetium-99m-di-isopropyl-iminodiacetic acid imaging in the demonstration of a biliary-bronchial fistula.

A case is described in which technetium-99m-di-isopropyl-iminodiacetic acid imaging was used to trace the passage of bile from its site of leakage into an amoebic liver abscess, through a fistulous tract connecting the liver abscess with an abscess in the right lower lobe of the lung, and into the upper respiratory tract.
