Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Bedside AP radiograph of the chest demonstrates near - complete opacification of the right hemithorax with interval development of pneumothorax . The pigtail catheter appears to lie in the expected location of the pleural space . There is increase in the degree of rightward tracheal deviation . Diffuse left lung opacities consistent with disseminated tumor as seen on the CT of the chest obtained at the same time . There is no left - sided pneumothorax or effusion .
    OUTPUT:
    
1 . Development of pneumothorax without tension , after chest tube placement , better evaluated on the CT of the chest performed at the same time . 2 . Opacification of the right hemithorax , when correlated with the CT findings , is mostly due to infiltration of airspaces with tumor as opposed to significant component of pleural fluid .
