[Cardiac rhabdomyomatosis and Bourneville's tuberous sclerosis in the fetus. Apropos of 2 cases].

Two cases of cardiac rhabdomyoma discovered fortuitously at foetal ultrasonography gave rise to no obstructive cardiac signs or arrhythmias either in the antenatal or postnatal periods. These multiple tumours often observed in Bourneville's tuberous sclerosis orientated the clinical investigations to the diagnosis of this disease from the outset. MRI demonstrated cortical tubers and subependymal nodules in both cases.
