Prenatal ultrasound diagnosis of multiple cardiac rhabdomyomas.

We report on a neonate with multiple cardiac rhabdomyomas, including a huge rhabdomyoma of the left ventricular posterior wall. Prenatal ultrasonography performed because of supraventricular tachycardia led to the diagnosis in the 28th week of gestation. Postnatal echocardiography confirmed the prenatal diagnosis. The tumor could not be removed surgically and the child died as a result of intractable arrhythmia at the age of 5 days. The diagnosis of multiple cardiac rhabdomyomas was confirmed by autopsy.
