Pericardial and myocardial localization of antimyosin in a case of acute myocarditis.
A 60-yr-old immunodepressed woman presented with acute perimyocarditis and cardiac tamponade complicating meningococcic infection. We had the opportunity to study her cardiac condition by injecting antimyosin during the acute phase. Images at 48 hr showed unexpected findings, with obvious localization of the tracer in the pericardial fluid, as well as myocardial uptake. Possible mechanisms for pericardial activity are discussed.
