title: [Two cases of Swyer-James syndrome].
abstract: Case 1: 55-year-old male was admitted to our hospital for further examination of increased transparency of X-ray in the left lower lung. He had history of pneumonia in his childhood. Left bronchography revealed mild cylindrical bronchi-ectasia in the proximal bronchi but poor filling by contrast in the peripheral bronchi. Case 2: 61-year-old male was referred to our hospital with palpitation and dyspnea. Chest X-ray film revealed hyperlucency of the left lower lung. The ventilation scan showed a marked decrease in ventilation to the left lung and air trapping was present in the left lung. The perfusion scan showed a matched decrease in blood supply to the left lung. In both cases, pulmonary arteriogram showed narrowed and withered-tree-like left pulmonary arteries. From these clinical findings, we diagnosed these two cases as Swyer-James syndrome. We are reporting two cases of Swyer-James syndrome and describing the clinical feature, differential diagnosis and etiology of the syndrome.
