Tuberous Sclerosis

The classic triad of seizures, mental retardation, and adenoma sebaceum is associated with tuberous sclerosis (TS), another autosomal dominant disorder. The most common imaging finding are tubers, which are hamartomas along the subependymal surface and cortex. These lesions tend to calcify. White matter glial abnormalities may also be present.
