Gliomas of the tectal plate in children
Keywords:
tumorof the tectal plate, hydrocephalus, astrocytomas, shuntingAbstract
A specific group of dorsal midbrain tumors was identified in 8 children by magnetic resonance imaging (MRT). Each patient presented with raised intracranial pressure as a result of hydrocephalus due to obstruction of the sylvian aqueduct. No patient had brain stem signs referable to the tectal tumor initially or subsequently.
All eight children underwent cerebrospinal fluid diversionary procedures. No patient underwent surgical resection or chemotherapy. Although intrinsic tectal lessons in children are clinically indolent and the initial management consists of CSF diversion, these lesions may eventually progress and still warrant long-term follow-up with serial MR-imaging.
