Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Compared to prior film , a pigtail catheter has been placed , left chest and the previously seen left - sided pneumothorax is no longer visualized . Given the degree of subcutaneous emphysema and supine positioning , a small or anterior pneumothorax minor be apparent on this film . Chain sutures noted in the left upper zone medially . There is patchy opacity in the left infrahilar and left lung base which appears more pronounced than on the prior study . A platelike area of atelectasis has improved . The left costophrenic angle is blunted , which could reflect some pleural fluid . Deformity of the of a left posterior posterolateral mid chest rib is compatible with prior surgery or trauma . Subtle angulation of 2 ribs along the left lower chest raises a question of more recent fractures , the lesion on confirmed on any CT obtained approximately 3 hr earlier . Opacities at the right lung base are again seen , possibly slightly improved . Blunting of the right costophrenic angle is compatible with a small effusion . There is vascular plethora , compatible with CHF . The ET tube , NG tube and right IJ line are nominal in position .
    OUTPUT:
    
Interval placement of left - sided pigtail catheter . Previous left - sided pneumothorax no longer visualized . Given the degree of subcutaneous emphysema and supine positioning , a small or anterior pneumothorax minor be apparent on this film . Vascular plethora , compatible with CHF . Bibasilar opacities , compatible with pulmonary infiltrates and / or changes secondary to aspiration . Small bilateral effusions .
