The Rare Cause Of Exertional Dyspnea: Swyer-James Syndrome

Swyer-James Syndrome is a rare pulmonary disease, characterized by one-sided hyperlucency, smaller hilum shadow and lack of vascular structures in affected side. Although usually asymptomatic, can also be symptoms such as recurrent lung infection, exertional dyspnea and hemoptysis. 23-year-old male patient presented with exercise-induced dyspnea. On physical examination, decreased breath sounds on the left hemithoraxes. Chest x-ray showed right middle and lower lobe more prominent hyperlucency, mediastinal shift to the left and small hilar shadow. Ventilation-perfusion scintigraphy were determined consistent defect areas. Swyer-James Syndrome diagnosed by chest X-ray is possible, but it is unthinkable because of the rarity. Swyer-James syndrome diagnosed patient is presented with literature data.
