Subacute hypersensitivity pneumonitis The key findings in the subacute hypersensitivity pneumonitis are: ill-defined centrilobular nodules of ground-glass opacity (80% of cases) or mosaic pattern of a combination of patchy ground-glass opacity due to lung infiltration and patchy lucency due to bronchiolitis with air trapping Here two examples of subacute hypersensitivity pneumonitis. There are ill-defined centrilobular nodules of ground-glass opacity. #Clinical #Radiology #CTChest #Hypersensitivity #Pneumonitis #HypersensitivityPneumonitis #Nodular #Subacute #Centrilobular #RadiologyAssistant
