This syndrome is characterized by unilateral hyperlucency on chest radiography. Computerized tomography provides useful additional information. The diagnosis is usually made in childhood, but sometimes occur in adulthood. The disease often presents with dyspnea, decreased exercise tolerance, cough, hemoptysis and recurrent pulmonary infections. Swyer-James-MacLeod Syndrome may be confused with asthma or pulmonary embolism due to similar symptoms and may result in inappropriate therapy. This case series examines the clinical and imaging spectrum of four patients who were diagnosed as SJMS in adulthood.
