[Post mortem brain MRI: an alternative for pathology examination in Bourneville tuberous sclerosis of the fetus?].

Antenatal discovery of cardiac rhabdomyomes evokes the diagnosis of Bourneville's disease. Antenatal brain exploration with ultrasonography and magnetic resonance imaging (MRI) can highlight cerebral localizations. In the event of termination of pregnancy, confirmation of the cerebral lesions can be achieved with post mortem MRI as well as pathology examination. MRI can be usefully employed in the event pathology examination is not feasible.
