    INPUT: Portable chest radiograph evaluation is somewhat limited by rotation . Interval removal of right - sided chest tube with possible interval development of a small right pneumothorax . Increased opacification of right upper lobe may reflect degree of associated collapse .

Stable cardiac enlargement with improved but persistent vascular congestion .
    OUTPUT:
    
Interval removal of right - sided chest tube with development of small right apical pneumothorax with new right upper lobe opacification , possibly representing degree of collapse . Improved vascular congestion and aeration of lung bases .
