Nonspecific prevascular lymphadenopath.  At the junction of the AP window and prevascular level is a 2.5x1.5 cm lymph node.  No other evidence of lymhadenopathy.  No pleural effusion.  No pericardial effusion.  Atherosclerotic coronary artery calcifications.  No evidence of aortic aneurysm.  Limited views of upper abdomen are unremarkable.  No pleural effusion.  No pericardial effusion. Artjerpsc;erptoc cprpmaru arteru calcifications.  No evidence of aortic aneurysm.  Limited views of upper abdomen are unremarkable.  The osseous structures are intact.
