FINDINGS:
A Port-A-Cath terminating in the upper part of the superior vena cava appears
 unchanged since the more recent of the prior two studies. The patient is
 status post sternotomy.  A calcified prevascular lymph node appears unchanged.
 The cardiac, mediastinal and hilar contours appear stable.  The lung volumes
 are low.  Streaky basilar opacity consistent with minor scarring is similar in
 the lingula.  There is no substantial parenchymal opacity.

IMPRESSION:
No evidence of acute disease.
