Sonographic diagnosis of fetal cardiac rhabdomyomas in two successive pregnancies in a woman with tuberous sclerosis.

Rhabdomyoma is the most common prenatally diagnosed cardiac tumor. We present two cases of fetal cardiac rhabdomyoma. In each case, fetal ultrasound assessment revealed the intracardiac tumors that were confirmed on postnatal imaging. The mother and her previous child were examined for the markers of tuberous sclerosis and diagnosis of tuberous sclerosis was confirmed. Two years later, cardiac rhabdomyomas were again diagnosed in her subsequent pregnancy. In the postpartum period, total regression of the tumors occurred in both cases.
