Cardiac sarcoidosis. A case with unusual manifestation.

A 26-year-old woman was hospitalized with new-onset congestive heart failure. M-mode and two-dimensional echocardiography revealed abnormal motion involving the apex and posterolateral wall of the left ventricle. Cardiac catheterization was performed. The left ventriculogram demonstrated apical akinesis and an apical filling defect. The diagnosis of cardiac sarcoidosis was made from an open myocardial biopsy.
