*Scheme illustrates types of neuropathologic changes in tuberous sclerosis complex. 1- isolated balloon cells in white matter, TSC-/-; 2- heterotopic cluster with dysplastic neurons TSC-/+; 3- subependymal nodules and 4- subependymal giant cell astrocytoma in ependyma of third ventricle (note that this is not usual localisation for both lesions, which is rather ependyma of lateral ventricles) 5- cortical tuber; 6 - linear migration streak. This scheme is based on DiMario, F Brain abnormalities in Tuberous Sclerosis Complex J Child Neurol, 9, 650-657. 2004.<ref>{{Cite journal | last1 = DiMario | first1 = FJ. | title = Brain abnormalities in tuberous sclerosis complex. | journal = J Child Neurol | volume = 19 | issue = 9 | pages = 650-7 | month = Sep | year = 2004 | doi = 10.1177/08830738040190090401 | PMID = 15563010 }}</ref> | |||
