Atypical Presentation of Infective Endocarditis With Native Aortic Valve Involvement Secondary to Staphylococcus aureus Bacteremia in the Setting of Non-Hodgkin Lymphoma.

Infective endocarditis (IE) is a condition that can involve endocardial tissue and possibly lead to valvular disease. Not only is it important to recognize the clinical presentation difference between acute and subacute IE, but physicians should understand that underlying risk factors, such as immunosuppression secondary to non-Hodgkin lymphoma (NHL), can alter an acute presentation into that of a subacute one. We report an NHL patient, who presented with subacute clinical symptoms of IE, but had a clinical test workup that showed evidence of acute IE rather than subacute.
