The presence of myocardial involvement is rare in benign Duchenne type of progressive muscular dystrophy (Becker's muscular dystrophy). We describe two brothers suffering from Becker's muscular dystrophy, both of whom presented with dilated cardiomyopathy. The first case is a 39-year-old male who had suffered from gait disturbance from the age of 17. ⋯ He came to our hospital with the chief complaint of discomfort of the anterior chest. Pseudohypertrophy of the calves was present. Chest radiography, electrocardiogram, ultrasonogram indicated dilated cardiomyopathy.
