Biliopleural Fistula Due to a Rare Liver Hydatid Cyst

Abstract
Hydatid cyst (HC) disease is a fecal orally transmitted parasitic infection caused by the larvae of Echinococcus tapeworms. In the human body, they cause parasitic infections most commonly in the liver. The second most common organ is the lungs. Biliopleural fistula (BPF) due to liver HC is a rare condition. Green pleural effusion and the pleural fluid/serum bilirubin ratio being >1.0 are supportive indicators of biliothorax. Treatment involves biliary drainage and diaphragm repair. A 53-year-old female patient. She consulted our hospital with complaints of abdominal pain and asthenia. She had undergone an operation for liver HC 8 years ago. Biliopleural fistula (BPF) was detected after examinations. Drainage and surgical treatment were performed on the patient who developed pneumothorax and biliothorax as a result of BPF.
