Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral views of the chest are obtained . Lung volumes are low which limits the evaluation . While there is no focal consolidation , there is a mild increase in interstitial opacity bilaterally could reflect crowding of bronchovasculature . An atypical pneumonia can not be excluded , however . No large pleural effusion or pneumothorax is seen . Heart size is normal . Mediastinal contour is unremarkable . Bony structures are intact .
    OUTPUT:
    
No lobar consolidation , though mild increase in interstitial opacity raises concern for atypical pneumonia .
