A rare case of myocardial calcification secondary to acute myocarditis due to an Escherichia coli infection

Myocardial calcification secondary to acute myocarditis is a rare but possibly life-threatening complication. We report a 43-year-old woman with minimal change nephrotic syndrome who developed sepsis caused by Escherichia coli. We simultaneously detected the complication of acute myocarditis in the patient. Although echocardiography showed hypokinesis of the apical segment when acute myocarditis was diagnosed, no sign of myocardial calcification was observed. After two weeks, a CT showed myocardial calcification in the same area. Although myocardial calcification was still observed 12 months later, the patient’s cardiac function had improved.
