Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Chest , PA and lateral . The lungs are hyperinflated . Again noted are diffuse , reticulonodular opacities , denser in the lower lungs . There is also increased linear opacities in the right lower lobe . There is a small right pleural effusion . Moderate cardiomegaly is stable . There is no pulmonary edema , however pulmonary vascular engorgement is noted . There is no pneumothorax .
    OUTPUT:
    
1 . Persistent reticulonodular opacities , with the recent chest CT demonstrating multiple stable pulmonary nodules with new diffuse interstitial lung disease raising the possibility of amiodarone toxicity , cryptogenic organizing pneumonia , or vasculitis . 2 . A new acute infectious process would be very difficult to exclude in the background of such extensive interstitial lung disease .
