Abstract

RONDINELLI, Patricia Imperatriz Porto; OSORIO, Carlos Alberto Martinez; COHEN, Marcela Pécora  and  NOVAES, Paulo Eduardo Ribeiro Santos. Unusual dissemination patterns of low-grade astrocytomas in childhood. Arq. Neuro-Psiquiatr. [online]. 2008, vol.66, n.1, pp.45-49. ISSN 0004-282X.  http://dx.doi.org/10.1590/S0004-282X2008000100011.

CONTEXT: Low-grade astrocytomas are intracerebral lesions of relatively high frequency in the under-18 pediatric population. They often present indolent behaviour, and complete surgical resection is the choice treatment. In cases where the surgery is not possible, chemotherapy and radiotherapy may be used. Medical reports do not recommend examination of the spinal cord at diagnosis or during treatment, since the risk of dissemination of the lesion to the spine is minimal according to medical experience. We describe here four cases of children with low-grade astrocytoma with aggressive dissemination to the neuroaxis.

Keywords : astrocytomas; pilocytic astrocytoma; brainstem tumor; brain neoplasms; children.
