[Congenital pulmonary cysts].

The clinical and surgical experience on congenital pulmonary cysts at the Hospital Infantil of México was reviewed. No preponderance in sex or family inheritance was found. The clinical diagnosis was made in over one half of the patients and was confirmed in the 18 patients who were operated. Treatment should be surgical with resection of the affected pulmonary lobe. In some cases it was possible to excise only the pumonary cyst, without total removal of the lobe. Mortality resulted in three of the surgical patients. The most frequent pulmonary cysts in this series were the bronchogenic and patients with parasitic cysts, lobe emphysema and pulmonary sequestrum were excluded.
