Acute myopericarditis associated with cat scratch disease in an adolescent.

Cat scratch disease is generally characterized by a self-limited chronic regional lymphadenopathy, but numerous other clinical manifestations involving a variety of organ systems have been reported. Cardiac involvement is unusual and when reported, it has been associated with culture-negative endocarditis in adults. We present the case of an adolescent male with typical cat scratch disease and associated myopericarditis.
