[Myocardial calcinosis in a juvenile patient with Wermer syndrome (multiple endocrine neoplasia type I)].

We describe the rare case of a 19 year-old patient with multiple endocrine neoplasia (Wermer syndrome), presenting with insulinomas as well as primary hyperparathyroidism. Echocardiography revealed evidence of calcific deposits in the interventricular septum. The latter may be explained by long-standing hypercalcemia.
