Résumé
We herein report a case of anti-MDA5 antibody-positive, clinically amyopathic dermatomyositis complicated by unilateral interstitial lung disease (ILD) in a 78-year-old man with a history of left lung tumor resection. He was admitted due to a persistent fever and abnormal right pulmonary opacity. A transbronchial lung cryobiopsy revealed pulmonary fibrosis, and combined immunosuppressive therapy was initiated. Findings from multiple evaluations, including dynamic breathing magnetic resonance imaging, supported decreased perfusion, ventilation, and mobility of the left lung as etiological factors of unilateral lung ILD. When patients present with laterality of such findings, clinicians should be aware that atypical imaging findings may be observed.
