Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart size is normal . The aorta is slightly unfolded and demonstrates marked aortic knob calcifications , unchanged . Opacities within the right hilum and right upper lobe abutting the fissure are unchanged , and compatible with known malignancy . Indistinctness and engorgement of the pulmonary vascular markings with associated haziness in the right lung likely reflects lymphangitic spread of tumor , though volume overload is not excluded , with increasing hazy opacification in the right lung base . Slight worsening of the streaky ill - defined opacity within the right lung base may also reflect right basilar atelectasis and / or infection . There is hyperinflation of the left lung with no new focal areas of consolidation identified . No pneumothorax is identified . A Pleurx catheter is seen with tip terminating at the right basilar hemithorax with a small right pleural effusion again noted , unchanged . There are mild degenerative changes in the thoracic spine .
    OUTPUT:
    
1 . Increased opacification within the right lung base may reflect worsening atelectasis and / or infection with superimposed lymphangitic spread of tumor or asymmetric pulmonary edema . 2 . Small right pleural effusion appears relatively unchanged , with Pleurx catheter in place . 3 . Re - demonstration of right hilar and right upper lobe masses compatible with known malignancy .
