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.
