[Cardiac metastases. Clinical arguments of the diagnosis]

The case reported here concerns an 80-year old man without history of coronary disease whose electrocardiogram showed localized and stable repolarization disorders, viz. elevated ST segment with isoelectric point J and negative T wave. This pattern suggested cardiac metastasis after chest examination had revealed a bronchial epidermoid carcinoma. Two-dimensional echocardiography showed that the lateral wall of the left ventricle was thickened, hyperechogenic and akinetic. The secondary cardiac lesions were confirmed at pathological examination. This case has prompted us to discuss the frequency of such secondary tumours of the heart, their mode of dissemination to the myocardium and their clinical and electrocardiographic aspects. It underlines the usefulness of echocardiography for the diagnosis of cardiac tumours.
