Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Cardiac silhouette is enlarged and has increased slightly in size since the prior radiograph . Aorta is tortuous . Increased opacity overlying the lower thoracic spine on the lateral view , and is difficult to localize on the frontal radiograph , but may involve both lower lobes as both hemidiaphragms appear slightly obscured posteriorly . Probable small bilateral pleural effusions are also demonstrated , with slight blunting of the posterior costophrenic angles . Bones are diffusely demineralized . Mild compression deformities in mid thoracic spine , unchanged since CT of ___ .
    OUTPUT:
    
1 . No definite findings to suggest active tuberculosis or previous granulomatous infection . 2 . Patchy bibasilar opacities could potentially reflect aspiration or bacterial pneumonia in the appropriate clinical setting . Short - term followup radiographs may be helpful to ensure resolution . 3 . Small bilateral pleural effusions . 4 . Cardiomegaly without evidence of pulmonary edema .
