Cardiac Sarcoidosis Mimicking Hypertrophic Cardiomyopathy

Abstract

A man with a presumed diagnosis of hypertrophic cardiomyopathy presented after a ventricular fibrillation arrest. Review of prior cardiac magnetic resonance imaging revealed a pattern of late gadolinium enhancement that was atypical for hypertrophic cardiomyopathy and most consistent with cardiac sarcoidosis, with diagnosis confirmed by endomyocardial biopsy. (Level of Difficulty: Beginner.)
