    INPUT: Frontal and lateral views of the chest were obtained . Patchy right mid - to - lower lower lung opacity seen on the frontal view is not substantiated on the lateral view and may be due to atelectasis or possibly vascular engorgement , consolidation is felt less likely . No pleural effusion or pneumothorax is seen . There is mild prominence of the hila which may be due to central pulmonary vascular engorgement with mild pulmonary vascular congestion . The cardiac silhouette is top normal . Mediastinal contours are unremarkable . There appeared to be some posterolateral right - sided rib deformities which may be due to prior trauma .
    OUTPUT:
    
Patchy right basilar opacity without priors for comparison may be due to atelectasis or vascular engorgement , consolidation felt less likely . Mild prominence of the hila may be due to central pulmonary vascular engorgement with mild vascular congestion .
