Ruptured pulmonary hydatidosis with bronchopleural fistula and eosinophilia: a case report

Hydatidosis is a parasitic illness caused by larvae of the Echinococcus genus. It frequently involves the liver, and the lung is the second most common organ of implantation of Echinococcus larvae. Pulmonary Hydatidosis leads to life-threatening complications, including pulmonary embolism, pleural effusion, and bronchopleural fistula. Although eosinophilia is not frequently detected in patients with hydatid disease, in patients with ruptured cysts in the biliary tree, eosinophilia is often marked. Herein, we present a case of pulmonary hydatidosis (with pleural fluid and peripheral eosinophilia) complicated by hydro-pneumothorax and bronchopleural fistula.
