Bronchobiliary fistula as a complication of liver metastases: diagnosis by HIDA scan.

Bronchobiliary fistulas are rare, may result from infection with Echinococcus or Amebiasis, trauma, or hepatic malignancy, and present with biliptysis, the expectoration of bile. The authors present a 49-year-old woman who presented with frank biliptysis as a result of previously treated metastatic colon cancer to the liver. A hepatobiliary scan is the noninvasive diagnostic imaging test of choice for demonstration of such fistulas, and was useful in confirming the diagnosis in our patient.
