An unexpected cardiac mass related to immunoglobulin G4-related disease

Year: 2026

Type: article

Abstract: A 54-year-old woman presented with palpitations of 3 months’ duration. Except for irregular pulse, the physical examination was normal. Electrocardiogram showed inferior ventricular extrasystoles. To understand these extrasystoles, an echocardiography was performed and revealed a well-delimited mass within the right ventricle (RV) measuring 24 × 21 mm that was mobile with blood flow without dilatation or RV dysfunction. Then, computed tomography (CT) and cardiac magnetic resonance imaging showed a calcified, pedunculated, nonobstructive, hyperenhanced mass in the RV outflow tract, a localization consistent with inferior ventricular extrasystoles (Figure 1 and Video 1).
