Subendymal

Neurologic symptoms and complications due to the development of cortical tubers, subependymal nodules and subependymal giant cell astrocytomas (SEGA) are common in patients with TSC.

(42,43) Apart from lymphatic endothelium, D2-40 has been reported to be immunoreactive in mesotheliomas (44,45) and, in the CNS, in choroid plexus epithelium, ependymal cells, subependymal areas, and the leptomeninges.

2c: Tuberous Sclerosis--T2W axial MR showing multiple hypointense subependymal nodules & band like white matter hyperintensities adjacent the body of lateral ventricle.

The tumor is thought to be derived from the granular neurons of the small gray nuclei of the septum pellucidum and fornix, or from remnants of the subependymal plate of the lateral ventricles.

MRI of brain shows presence of multiple cortical tubers, subependymal nodules and subependymal calcific lesions.

Grade 1: Subependymal haemorrage with no inferior or lateral extension of blood beyond the most lateral border of ventricle.

Sudden death in epilepsy due to an isolated subependymal giant cell astrocytoma of the septum pellucidum.

Gliomas (a) Astrocytomas: Circumscribed-juvenile pilocytic astrocytoma, pleomorphic xanthocytoma, subependymal giant cell astrocytoma, diffuse, optic pathway glioma, anaplastic astrocytoma, glioblastoma multiforme (b) Oligodendrogliomas (c) Ependymomas (d) Choroid plexus tumors--papilloma or carcinoma.

Melanosis of the choroid plexus, ependyma, subependymal neuroglia, and dentate and trigeminal motor nuclei: observations on the choroidal and ependymal cilia.

(7) CT may show subependymal or parenchymal calcification in many cases, which suggests that one cause of schizencephaly may be intrauterine infection with cytomegalovirus.

Optic gliomas, subependymal giant cell astrocytomas (SEGAs), pleomorphic xanthoastrocytomas (PXAs), mixed gliomas with oligodendroglial features (oligoastrocytomas), and gangliogliomas were excluded.
