Abstract

IgG4-related lung disease (IgG4-RLD) can present with various types of radiological findings such as nodule, ground-glass opacity, alveolar interstitial, and bronchovascular involvement. IgG4-RLD generally manifests as mild clinical symptoms, despite evidence from the image findings. Herein we report an asymptomatic patient with IgG4-RLD mimicking multiple pleural disseminated lung cancer.

Keywords: IgG4; IgG4 related lung disease; immunologic abnormality; lung cancer; subpleural pulmonary nodule.
