Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart size is difficult to assess given the presence of a moderate right pleural effusion , but is likely mildly enlarged . The aorta is tortuous and diffusely calcified . There is no pulmonary vascular congestion , and there is no definite hilar enlargement . Right basilar opacification likely reflects a combination of moderate pleural effusion and right basilar atelectasis . Small left pleural effusion is also demonstrated with minimal streaky retrocardiac atelectasis . No pneumothorax is present . A catheter is seen coursing across the midline and terminating in the region of the right upper abdomen or lung base , but appears to have moved between the frontal and lateral views . Multilevel degenerative changes are noted in the thoracic spine .
    OUTPUT:
    
Moderate size right pleural effusion and small left pleural effusion with bibasilar opacities likely atelectasis .
