RT Journal Article SR Electronic T1 Adult Diagnosis of Swyer-James-Macleod Syndrome: Retrospective Analysis of Four Cases JF Respiratory Care FD American Association for Respiratory Care SP e51 OP e54 DO 10.4187/respcare.02552 VO 59 IS 4 A1 Hadice Selimoglu Sen A1 Mahsuk Taylan A1 Ozlem Abakay A1 Cengizhan Sezgi A1 Mehmet Guli Cetincakmak YR 2014 UL http://rc.rcjournal.com/content/59/4/e51.abstract AB Swyer-James-Macleod syndrome (SJMS) is a rare constrictive bronchiolitis with air-flow obstruction and a decreased number and diameter of ipsilateral peripheral pulmonary vessels. This syndrome is characterized by unilateral hyperlucency on chest radiography. Computed tomography provides useful additional information. The diagnosis is usually made in childhood but sometimes occurs in adulthood. The disease often presents with dyspnea, decreased exercise tolerance, cough, hemoptysis, and recurrent pulmonary infections. SJMS may be confused with asthma or pulmonary embolism due to similar symptoms and may result in inappropriate therapy. This case series examined the clinical and imaging spectrum of four patients who were diagnosed with SJMS in adulthood.
