Pleurobiliary fistula secondary to choledocholithiasis - A rare entity

Pleurobiliary fistula secondary to common bile duct obstruction due to stone is a very rare clinical entity. A 55-year-old female patient presented in the emergency department with features of septicaemia with left pleural effusion. Intercostal tube drainage drained 5 L of bile on the first day and around 500-600 mL of bile each day subsequently. Magnetic resonance cholangiopancreaticography showed choledocholithiasis with pleurobiliary fistula. The patient underwent bilioenteric bypass and ligation of the fistulous tract with complete cure.
