FINDINGS:
Right chest tube remains in constant position.  Small apical right
 pneumothorax without evidence of tension is unchanged.
 
 Severe infiltrative pulmonary abnormality is unchanged. Its persistence since
 suggests a generalized drug reaction or hemorrhage.  The heart is not
 enlarged.  No pulmonary vascular engorgement to suggest edema.

IMPRESSION:
1. Unchanged small apical right pneumothorax with constant right chest tube
 position.
 
 2. Persistent severe infiltrative pulmonary abnormality suggests a generalized
 drug reaction or hemorrhage.
