In many cases the first clue to recognizing TSC is the presence of seizures or delayed development. Brain involvement in TSC Three types of brain lesions are seen in TSC: cortical tubers, for which the disease is named, generally form on the surface of the brain but may also appear in the deep areas of the brain: subependymal nodules (SEN), which form in the walls of the ventricles -- the fluid-filled cavities of the brain; and subependymal giant-call astrocytomas (SEGA), which develop from SEN and grow such that they may block the flow of fluid within the brain, causing a buildup of fluid and pressure and leading to headaches and blurred vision.
