    INPUT: The left costophrenic angle and left diaphragm are not included on the frontal view . The posterior costophrenic angles are not fully included on the lateral view ; however , no large pleural effusion is seen . The cardiac silhouette remains enlarged . The aorta is calcified and tortuous . Streaky opacity at the right lung base is similar to priors and most likely relates to atelectasis / scarring . There is mild prominence of the hila , suggesting vascular engorgement .
    OUTPUT:
    
Streaky opacity at the right lung base , similar to prior , suggests atelectasis / scarring rather than infection ; however , early infectious process is not excluded in the appropriate clinical setting .
