    INPUT: Compared to the prior examination , there has been increase in size of right - sided pleural effusion as well as worsening of right base consolidation with mild rightward mediastinal shift . The right main stem bronchus is difficult to visualize distally and may be plugged with mucus . A previously described right apical pneumatocele is more fluid filled compared to prior study . Post-radiation changes in the right lung are unchanged . Pulmonary edema in the left lung is improved . A small left - sided pleural effusion is unchanged . A left - sided port remains in unchanged position with the tip at the cavoatrial junction . There is no pneumothorax .
    OUTPUT:
    
Increasing right base consolidation and effusion with slightly increased rightward mediastinal shift and difficult visualization of the right main stem bronchus suggesting collapse with airway obstruction from mucus plugging .
