[Myocarditis caused by Trichinella spiralis: a case report].

Trichinellosis is a cosmopolitan nematodosis which is rare in the developed countries. Myocarditis represents the most frequent form of cardiac complications, sometimes lethal. The authors report the observation of a 36-years-old patient admitted for trichinellosis, who presented asymptomatic electrocardiographic modifications and a rise in the troponine I. The magnetic resonance imaging (MRI) after gadolinium injection, highlighted an underepicardic late raising rendering the diagnosis of myocarditis highly probable. The paraclinic anomalies were corrected gradually under antiparasitarian treatment. Besides the EKG, the MRI is a non-invasive and repetitive method allowing as well the positive diagnosis as the follow-up of those patients.
