Diagnosis of Traumatic Bronchobiliary Fistula With Late 99mTc-Mebrofenin SPECT/CT

Abstract

Bronchobiliary fistula (BBF) represents a rare disorder; it consists of abnormal interconnection between the biliary tract and bronchial trees. A 22-year-old woman with persistent chest pain, jaundice, and biliptysis was referred for hepatobiliary scintigraphy under clinical suspicion of a BBF. Patient medical history was consistent with biliary tree reconstruction secondary to an iatrogenic injury during cholecystectomy 4 years ago. Previous complementary studies (CT and MR cholangiopancreatography) were equivocal for diagnosis. Planar dynamic images of hepatobiliary scintigraphy in the first hour were inconclusive. A 24-hour SPECT/CT was performed and confirmed the BBF in a minimally invasive way.
