Cardiac sarcoidosis masquerading as arrhythmogenic right ventricular cardiomyopathy: a case report.

ABSTRACT:

Background

Cardiac sarcoidosis (CS) and arrhythmogenic right ventricular cardiomyopathy (ARVC) are rare causes of ventricular arrhythmias and are associated with sudden cardiac death. Differentiation between both is important for proper management.

Case summary

We present a 56-year-old man with sudden cardiac arrest and was diagnosed to have ARVC based on cardiac magnetic resonance imaging (MRI). He developed gradually worsening shortness of breath over the next 1 year. CS was unmasked after a cardiac positron emission tomography (PET). Patient was treated with methotrexate. A repeat cardiac PET scan showed improvement.

Discussion

The distinction between ARVC and CS is challenging. Both these entities have a patchy involvement and can have similar presentations. ARVC
