Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size is top - normal . The aorta is tortuous . Mediastinal and hilar contours are otherwise unremarkable . A small left hydropneumothorax is present with accentuation of the pneumothorax component at the apex on the expiratory view . Small right pleural effusion is also noted . Patchy opacities are demonstrated in the lung bases , potentially atelectasis , but contusion is not excluded . Pulmonary vasculature is not engorged . Deformity of the left sixth lateral rib likely reflects a rib fracture .
    OUTPUT:
    
1 . Small left hydropneumothorax . 2 . Small right pleural effusion . 3 . Bibasilar patchy opacities , likely atelectasis , but contusion is not excluded . 4 . Left lateral sixth rib fracture .
