    INPUT: Slightly rotated positioning . The tip of the tracheostomy tube lies approximately 2 .8 cm above the carina . The cardiomediastinal silhouette is probably unchanged . Again seen is left lower lobe collapse and / or consolidation , possibly with a small left effusion . Opacity in the right upper zone medially is more pronounced on the current examination . There due to appear to be associated air bronchograms . Opacity at the right base appears improved , with improved visualization of the right hemidiaphragm . A small right effusion remains present . Again seen is the right sided Port - A - Cath , with tip in the region of the cavoatrial junction . The left IJ central line is again seen , with tip over mid / distal SVC . Although it is difficult to confirm the patient 's position , there is suggestion of left convex rotary scoliosis of the lumbar spine . It remains possible , albeit less likely , that this is an artifact due to positioning . Rounded iatrogenic structure over the left lower abdomen is compatible with a gastrostomy tube .
    OUTPUT:
    
Tracheostomy tube again noted , as described . Persistent left lower lobe collapse and / or consolidation , possibly with a small left effusion . New opacity in the right upper zone medially extending to the right hilum . The appearance is suggestive of a new area of focal consolidation . If clinically feasible , the differential diagnosis could include an area of aspiration . Atelectasis can occur in this location , but is considered less likely given the presence of air bronchograms . Interval improvement of aeration at the right lung base , with some persistent patchy opacity at the right lung base and a small right pleural fusion .
