A 40-year-old male presented to the emergency department complaining of palpitations and was found to be in stable monomorphic ventricular tachycardia (Figure 1). He underwent a thorough diagnostic workup. Cardiac catheterization revealed normal coronary arteries and endomyocardial biopsy was nondiagnostic. However, based on findings from multiple imaging modalities including cardiac MRI (Figure 2), transthoracic echocardiography (Figure 3A), and cardiac PET (Figure 4, first and second rows; and Figure 5), a clinical diagnosis of cardiac sarcoidosis was made. High-dose steroids were initiated and he underwent placement of an ICD before discharge. After completing a course of steroids, repeat imaging revealed improved left ventricular function and resolution of regional cardiac inflammation (Figure 3B; and Figure 4, third row). The patient continues to do well clinically with no symptoms or arrhythmias.
