Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size is mild to moderately enlarged , unchanged . Mediastinal and hilar contours are similar with tortuosity of the thoracic aorta again seen . Pulmonary vasculature is not engorged . Small to moderate size right pleural effusion is similar to the previous chest CT . There also appears to be a small left pleural effusion . Streaky opacity within the right lung base likely reflects compressive atelectasis as does minimal patchy retrocardiac opacity . Assessment of the medial lung apices is limited due to obscuration from soft tissues of the patient 's chin and neck , however no large pneumothorax is present . Multiple left - sided remote rib fractures are present . Burst fracture of a mid thoracic vertebral body with focal kyphosis appears unchanged . Hardware within the proximal right humerus is incompletely assessed .
    OUTPUT:
    
Moderate size right and small left bilateral pleural effusions with bibasilar atelectasis . Known pulmonary nodules are better assessed on the prior CT .
