Cardiac tumour in a neonate with tuberous sclerosis: echocardiographic demonstration and magnetic resonance imaging.

In a neonate with tuberous sclerosis, cardiac tumours were diagnosed by two-dimensional echocardiography and evaluated by electrocardiogram-gated magnetic resonance imaging (MRI). The tumour size, shape and mobility in the ventricular cavities were more precisely determined by two-dimensional echocardiography than electrocardiogram-gated MRI, while the extent of tumour mass at the apex was more clearly delineated by MRI. As two-dimensional echocardiography provides real-time imaging of cardiac anatomy without sedation, it is useful for initial evaluation of cardiac masses in neonates with genetic predisposition to tuberous sclerosis.
