Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest . The lung volumes are very low and there is resultant crowding of bronchovascular structures , especially at the bases . An apparent more confluent opacity in the posterior basal left lower lobe is noted . Both the low lung volumes and AP technique accentuate the cardiomediastinal contours . There is no large pleural effusion or pneumothorax .
    OUTPUT:
    
Low lung volumes makes assessment for hilar lymphadenopathy and evaluation of an apparent left posterior basilar opacity difficult . When the patient 's condition permits , PA and lateral radiographs with a deeper inspiration are recommended to better assess the hilar structures and to re-evalute the posterior basal left lower lobe .
