Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Right - sided Port - A - Cath tip terminates in the lower SVC , unchanged . There is worsening volume loss in the right lung with increased rightward shift of mediastinal structures and evidence of right lower lobe collapse , worse since the previous radiograph . Right hilar lymphadenopathy is re- demonstrated , and known right lower lobe mass is not well assessed on this current exam , though there is abrupt cut off of the right bronchus intermedius in the region of the mass compatible with obstruction . Patchy opacity within the right mid lung field may also reflect postobstructive atelectasis or pneumonia . The left lung is hyperinflated without focal consolidation . Moderate size right pleural effusion is increased from the previous study . There is no pneumothorax . Pulmonary vasculature is not engorged . Cardiac silhouette size is difficult to assess given the presence of right lower lobe collapse . No acute osseous abnormality is detected .
    OUTPUT:
    
Worsening opacification in the right lung base compatible with increased right lower lobe collapse and potential post obstructive infection . Known right hilar lymphadenopathy and right lower lobe mass are better visualized on the prior PET - CT . Moderate size right pleural effusion , increased in the interval .
