Abstract
Clinical studies have been made upon 10 cases diagnosed as bronchogenic pulmonary cyst according to Kumagai's classification. The 10 investigated cases are comprised of 2 cases of solitary cyst. 5 cases of them underwent pneumonectomy and other 5 cases were lobectomized.
Clinical findings of these cases of bronchogenic pulmonary cyst in comparison with those of cases of bronchiectasis are as follows:
1) As to subjective symptoms, cases of bronchiectasis generally complain of accumulated sputum and cases of bronchogenic pulmonary cyst of ten either have no complaint of sputum or fall into suddenly developing dyspnea in their twenties.
2) In radiological findings, cases of bronchiectasis generally show accentuated linear shadow consisting of pulmonary vessels and bronchi radiated from hilum, and cases of bronchogenic pulmonary cyst generally show honey-comb like shadow.
As to indication of the surgical treatment for bronchogenic pulmonary cyst, pulmonary resection is considered to be effective with consideration of pulmonary function in cases with remittent inflammation or with cysts scattered widely in the unilateral lung.
