Chronic myocarditis is sometimes difficult to diagnose using several clinical diagnostic modalities. A 43-year-old Japanese man was admitted to our hospital with heart failure due to a diffusely hypokinetic left ventricle. No abnormal accumulation was seen on 18 F-fluorodeoxyglucose positron emission tomography/computed tomography. Coronary angiography showed no abnormalities. Endomyocardial biopsy was performed on suspicion of dilated cardiomyopathy, revealing diffuse cell infiltration (more T lymphocytes associated with macrophages than B cells on immunohistochemical staining), myocyte damage, and replacement fibrosis. The pathological diagnosis of biopsy specimen was difficult to differentiate between chronic myocarditis and inflammatory dilated cardiomyopathy without immunohistochemistry. Endomyocardial biopsy offers one of the most useful methods for diagnosing chronic myocarditis.
