Congenital brain tumours are rare. They account for 0.5% to 1.9% of intracranial tumours in childhood and have an incidence of 0.34 per million live births. Most congenital brain tumours are neuro-ectodermal tumours and medulloblastomas; giant cell astrocytoma and other tuberous sclerosis-related tumours are rare. We report on a neonate who developed seizures that were refractory to medical tre...
Tuberous sclerosis complex Syndrome (TSCs) is an autosomal dominant disorder affecting multiple organs; caused by mutations of either the TSC1 or TSC2 gene encoding hamartin and tuberin respectively. It is characterized by the development of benign tumours affecting different body systems. The most common visible manifestations of TSC are facial angiofibromas and the formation of hamartomas in ...
Of 488 central nervous system neoplasms occurring in children over a 39-year period, 467 were intracranial and 21 were intraspinal. The most common intracranial neoplasms were astrocytoma (28%), medulloblastoma (25%), ependymal neoplasm (9%), craniopharyngioma (9%), and glioblastoma multiforme (9%). The median age at diagnosis was 6 years with a male-to-female ratio of 1.3:1. Overall mean survi...
INTRODUCTION Tuberous sclerosis (TS) is an autosomal dominant neuro-cutaneous syndrome characterized by multiple hamartomas in various organs, especially on skin and central nervous system. The most common features of TS include facial angiofibromas, hypomelanotic cutaneous macules, shagreen patches in the lumbar area, cerebral cortical tubers, sub-ependymal nodules, sub-ependymal giant cell as...
Two cases of tuberous sclerosis with subependymal giant cell astrocytoma are presented. This rare autosomal dominant disorder was also detected in family members of the patients who had never had any symptoms of cerebral involvement. Both patients underwent surgery because of signs of increased intracranial pressure.
