| Summary: | Immunoglobulin G4 (IgG4)-related disease (IgG4-RD) is a fibroinflammatory disorder that can involve
any organ system; however, myocarditis is extremely rare. A 52-year-old male with dyspnea and chest
discomfort underwent cardiac MRI that revealed edema and nodular, patchy, mesocardial and subendoardial
delayed enhancement of left ventricle, suggesting myocarditis. Laboratory findings revealed
elevated serum IgG4 and eosinophilia. Cardiac biopsy confirmed eosinophilic myocarditis
with IgG4-positive cells. Here, we present an unusual case of IgG4-RD manifesting as eosinophilic
myocarditis. |
