[Left ventricular thrombus and myocarditis induced by paraphenylenediamine poisoning].

We showed that the paraphenylenediamine (PPD) poisoning caused myocarditis but there is no data on the echocardiographic features. We report a case of myocarditis induced by PPD poisoning with echographic data. After ingestion of 5 g of PPD, a 18-year-old woman was admitted to the hospital with asphyxia and rhabdomyolysis. An electrocardiogram showed ventricular extrasystoles and negative T waves. The serum concentration of CK was 28,020 UI l(-1) (iso-enzyme MB = 840 UI l(-1)). A transthoracic echocardiography showed significant left and right ventricular hypokinesis (shortening fraction = 20% and left ventricular ejection fraction = 35%) and a left ventricular apical thrombus. Anticoagulation treatment with heparin was initiated. A follow-up echocardiogram performed on the 15th day showed normalization of ventricular function and disappearance of the thrombus. No embolic event was noted. Echocardiography is indicated in the myocarditis induced by PPD poisoning to prove the ventricular function as well as the presence of a thrombus.
