    INPUT: The cardiomediastinal silhouettes are stable and within normal limits . There is a mildly tortuous thoracic aorta , as on prior exams . Patchy airspace opacity in the right lower lung likely relate to a suboptimal inspiratory effort in the setting of low lung volumes , however developing infection should be considered in the correct clinical setting . There is no evidence of focal lung consolidation elsewhere . There is no evidence of pulmonary vascular congestion . There is no pneumothorax or pleural effusion .
    OUTPUT:
    
Patchy right lower lung airspace opacity likely due to a suboptimal inspiratory effort . Early infection can not be excluded , recommend attention on followup .
