[Some interesting cases of pulmonary echinococcosis].

The authors had the opportunity in the interim of the past fifteen years to treat at the hospital in Zadar 277 patients suffering from hydatid disease of different body organs. The most frequently affected was the liver--56.3%, followed by the lungs--24.9% and 18.8% were other organs. Out of the 69 cases of affected lungs, the authors chose several which they considered to be most interesting. These consisted of: 1. A fistula between the cyst in the liver and the right lung. 2. A syndrome of the middle lung lobe caused by the hydatid cyst. 3. The Cumbo's symptom following a perforated lung cyst as a definite sign of hydatid cyst. 4. A hydatid cyst in a two years old child complicated with pneumothorax, peripnemocyst and perforation of the cyst itself in the bronchus. And finally 6. The case of a primary liver cyst which perforated in the vena cava caudalis with secondary dissemination in both lungs.
