    INPUT: Multifocal consolidative opacities are again demonstrated within the upper and lower lobes bilaterally , perhaps slightly improved in the right lung but appear worse in the left lung . Additionally new moderate size pleural based opacity is seen laterally within the left hemithorax , likely reflecting a partially loculated left pleural effusion . No pneumothorax is identified . There is no pulmonary edema . Heart size is difficult to assess given the left basilar consolidation . Mediastinal contour appears unchanged . There are no acute osseous abnormalities .
    OUTPUT:
    
Multifocal consolidative opacities in both lungs compatible with pneumonia , perhaps slightly improved in the right lung , but appears worse in left lung though this may be compounded due to the presence of atelectasis . Interval development of new moderate sized partially loculated left pleural effusion .
