Multimodal imaging findings in an adult case of Swyer-James-MacLeod syndrome.

Swyer-James-MacLeod syndrome (SJMS) is an uncommon obliterative lung disease that is radiologically characterized by hyperlucency of a part of or the entire lung. A 33-year-old man presented to our hospital for chest tightness. A chest X-ray revealed unilateral hyperlucency of left lower lung, and contrast-enhanced computed tomography (CT) of the chest disclosed a hyperlucent left lung without vascularity. Three-dimensional CT reconstruction and ventilation-perfusion scan findings were concordant with SJMS. We herein report a case of SJMS in a patient who showed the characteristic multimodal imaging findings.
