Tuberous sclerosis is a rare genetic disorder resulting in benign tumor growth in various organs including the brain, heart, skin, eyes, kidney, and lung as well as systemic manifestations including seizures, cognitive impairment, and dermatologic abnormalities. This report shows the radiological findings and differentiation between a subependymal nodule and subependymal giant cell astrocytoma ...
Background: Tuberous sclerosis (TSC) is inherited as an autosomal dominant disease, characterized by skin lesion and tubers in vital organs, especially brain in three categories including subependymal nodules, cortical tubers and subependymal giant cell astrocytoma. Subependymal giant cell astrocytoma (SEGA) is an indolent neoplasm which usually arises at the cauda tha...
Changes in ventricular size and brain parenchyma were documented in 40 preterm neonates with intracranial hemorrhage (ICH), who were serially examined for 3 weeks or more. Sonography disclosed a close relation between the severity of the intracranial hemorrhage and the development of progressive ventricular dilatation. Eighty percent of preterm neonates with minor degrees of intracranial hemorr...
BACKGROUND Tuberous sclerosis complex is a genetic disorder leading to constitutive activation of mammalian target of rapamycin (mTOR) and growth of benign tumours in several organs. In the brain, growth of subependymal giant cell astrocytomas can cause life-threatening symptoms--eg, hydrocephalus, requiring surgery. In an open-label, phase 1/2 study, the mTOR inhibitor everolimus substantially...
The early development of the mammalian forebrain involves the massive proliferation of the ventricular zone cells lining the lateral ventricles. A remnant of this highly proliferative region persists into adult life, where it is known as the subependymal layer. We examined the proliferation kinetics and fates of the mitotically active cells in the subependyma of the adult mouse. The medial edge...
BACKGROUND AND PURPOSE The anatomy of the deep venous system plays an important role in the pathogenesis of brain lesions in the preterm brain as shown by different histological studies. The aims of this study were to compare the subependymal vein anatomy of preterm neonates with germinal matrix haemorrhage-intraventricular haemorrhage (GMH-IVH), as evaluated by susceptibility-weighted imaging ...
The incidence and outcome of epilepsy in tuberous sclerosis (TS) patients have not yet been thoroughly investigated. The aim of this study was to evaluate the clinical features and prognosis of epileptic seizures associated with TS. The medical records of 29 patients who satisfied the diagnostic criteria for TS and were followed up for at least 2 years at the Department of Pediatrics, Chonnam N...

Background Tuberous sclerosis (TSC) is inherited as an autosomal dominant disease, characterized by skin lesion and tubers in vital organs, especially brain in three categories including subependymal nodules, cortical tubers and subependymal giant cell astrocytoma. Subependymal giant cell astrocytoma (SEGA) is an indolent neoplasm which usually arises at the cauda thalamic groove near foramen m...
