Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Chest radiograph evaluation , particularly the left heart border , is limited due to patient rotation . Within this limitation , there appears to be an opacity projecting over the left heart border , possibly representing lingular pneumonia . Coarsened interstial markings evident in the lung bases , may reflect differences in technique . No pneumothorax or pleural effusion evident . The patient is status post CABG with stable cardiac enlargement . Mediastinal and hilar silhouettes are unremarkable . Significant thoracolumbar scoliosis with associated degenerative changes identified . Deformity of left clavicle likely due to prior trauma .
    OUTPUT:
    
Unable to assess lingula due to rotation . No pneumonia evident .
