Myocardial calcification is a rare echocardiographic finding, which is often found in patients who have suffered from a myocardial infarction. Rarely, myocardial calcification may be present in individuals without a significant medical history. Until today, there has not been a published case report emphasising the relation between myocardial calcification and cocaine usage. Herein, we report a case of a young male with diffuse calcification of the left ventricular myocardium, who had an addiction to cocaine. This case highlights an uncommon etiology for myocardial calcification and it may lead to further studies about cardiotoxic effects of cocaine.
