Demostración de fístula biliobronquial mediante resonancia magnética con contraste hepatoespecífico

Bronchobiliary fistulas are a rare entity of difficult diagnosis. The utility of magnetic resonance image (MRI) with hepatospecific contrast agents to demonstrate such condition is seldom described in the literature. This case reports a patient with pulmonary infection with a past history of hepatic surgery for hydatid disease in whom the presence of bile in the sputum rose the suspicious of a bronchobiliary fistula.
