Oncologic Brugada.

Structural abnormalities within the right ventricular outflow tract (RVOT) can present similarly to Brugada syndrome. A 34-year-old woman with no medical history presented with polymorphic ventricular tachycardia/ventricular fibrillation cardiac arrest and initial electrocardiogram showed type I Brugada pattern. Cardiac magnetic resonance imaging revealed prominent tissue thickening at the RVOT with late gadolinium enhancement. Although imaging findings met criteria for arrhythmogenic right ventricular cardiomyopathy, thickening and infiltration in the anteroseptal RVOT is atypical, raising concern for an infiltrative process. Cardiac biopsy revealed primary cardiac diffuse large B-cell lymphoma.
