Known case of tuberous sclerosis on antiepileptic treatment. Subcortical white matter lesions showing low T1 and high T2 intensities and no enhancement that mostly represent subcortical tubers.

Bilateral subependymal lesions mostly represent subependymal hamartomas. The possibility of subependymal giant cell astrocytomas couldn't be excluded and so serial follow-up for the size of subependymal nodules is recommended.
