Computed Tomography of Chest in Non-Infectious Granulomatous Lung Diseases: A Pictorial Essay
View through CrossRef
Non-infectious granulomatous lung diseases represent a group of disorders with relatively non-specific clinical history and imaging findings. Following pathologies are enlisted, (1) Inflammatory: sarcoidosis and necrotizing sarcoid granulomatosis (NSG); (2) Pulmonary lymphoid lesions: lymphomatoid granulomatosis (LYG) and granulomatous-lymphocytic interstitial lung disease (GLILD); (3) Aspiration/exposure: aspiration pneumonia, talcosis, berylliosis, and hypersensitivity pneumonitis (HP); (4) Vasculitis: granulomatosis with polyangiitis and eosinophilic GPA (EGPA) (formerly called as Churg-Strauss syndrome); and (5) Collagen vascular disorders: rheumatoid lung nodules. Role of radiologist is to narrow the diagnosis combining the imaging findings with clinical findings thus following a multidisciplinary approach.
