Multivalve endocarditis with multiple peripheral and pulmonary embolisms: a case report.

Fever of unknown origin in elderly patients is a difficult diagnostic problem. Infective endocarditis is often not diagnosed in this group of patients, in whom other etiologies like cancer are considered first. The authors report a case in which an elderly woman with subacute mitral and tricuspid infective endocarditis was correctly diagnosed only after a peripheral embolism. Besides having multiple pulmonary and peripheral embolisms, she developed a left femoral mycotic aneurysm.
