Role of Cholescintigraphy with Single-Photon Emission Computerized Tomography-Computed Tomography in Detecting Bronchobiliary Fistula: Unusual Complication of a Common Disease.

Bronchobiliary fistula (BFF) is an abnormal communication between the biliary tree and airway. A patient usually presents with cough and bilioptysis, and at times, it poses diagnostic and therapeutic challenge. This case demonstrates the usefulness of cholescintigraphy with single-photon emission computerized tomography in diagnosing BFF in case of hydatid cyst of the liver.
