Intracranial tuberous sclerosis in infancy.

Transfontanelle sonograms and CT scans of the brain were obtained in 2 infants with tuberous sclerosis. Each modality showed typical subependymal nodules in both infants, as well as a large mass adjacent to the foramen of Monro in one of them; in the other, peripheral cortical tubers were clearly outlined with CT but not detected by ultrasound.
