title: [Pilocytic astrocytoma with subarachnoid dissemination].
abstract: Pilocytic Astrocytomas (WHO I) are histopathologically tumors of glial origin occurring predominantly in childhood and adolescence. Normally, they are characterized by a benign clinical course, with a long overall survival time and a high rate of complete remission. The rare case of pilocytic astrocytoma, primarily located in the third ventricular region, with generalized subarachnoidal spread is described. In the 10 years of follow-up, the histopathologic findings of the seedings remained those of a typical pilocytic astrocytoma; tumor progression did not occur.
