[Metastatic echinococcosis as a rare differential diagnosis of therapy refractory bronchitis]

In a 68 year old male german patient we found a transdiaphragmatic perforation of a superinfected liver echinococcus granulosus cyst into the bronchial system as cause of a purulent bronchitis resistant to treatment. After operative removal and oversewing of diaphragm bronchitis was cured and the patient could be discharged.
