    INPUT: Frontal AP and lateral views of the chest were obtained . Right basilar opacity is likely due to a combination of pleural effusion and atelectasis as seen on the concurrent CT abdomen . A rounded opacity in the right mid lung is likely loculated fluid in the right major fissure , given the partially loculated pleural effusion . The right upper lung zone and the left lung are clear aside from mild left basilar atelectasis . Heart size is top normal . The aorta is tortuous . Hilar contours are normal .
    OUTPUT:
    
Partially loculated right pleural effusion . A right mid lung opacity is likely fluid in the major fissure . Followup CXR is recommended to ensure resolution .
