    Abstract:
    Tectal glioma is a topographical diagnosis including tumors of different histology, mainly low-grade astrocytomas. Clinical symptoms are usually associated with increased intracranial pressure. This report discusses the management of this rare tumor in children. Clinical charts of 12 children with tectal glioma treated in our department between 1976 and 2001 were retrospectively reviewed. The mean age at the time of diagnosis was 6.75 years (range, 4 weeks to 16 years). The duration between first symptoms and the diagnosis of tectal glioma was in the range of 2 days to 9 years. Ten patients presented with symptoms associated with increased intracranial pressure, one patient presented with ataxia, and in one case tectal glioma was an incidental finding. First-line therapy was endoscopic third ventriculostomy in 5 cases (42%), ventriculoperitoneal shunting in 6 cases (50%), and combined partial tumor resection and shunting in one case. Histology was obtained in 5 cases (low-grade astrocytoma, n = 4; ependymoma, n = 1). All patients had good neurologic function at the end of follow-up. Tectal glioma represents a distinct subgroup of brainstem tumors associated with a good (or favorable) prognosis. Effective treatment for hydrocephalus is essential; the tumor should be monitored by regular clinical examination and magnetic resonance imaging. Biopsy is warranted in cases with tumor progression.
