Focal tectal tumors: management and prognosis

A 7-year review at our institution identified 12 children with midbrain tectal tumors. All presented with signs of increased intracranial pressure, had hydrocephalus on initial imaging, and were treated with ventriculoperitoneal (VP) shunts. Three had clinical and radiographic progression of disease. Two were treated with radiation and chemotherapy, with progression of disease in one. The third received radiation alone. All patients are alive, with a median follow-up of over 4 years. Median progression-free survival is at least 24 months and median total survival is beyond 50 months. The tectal glioma syndrome is a relatively benign variant of the brainstem glioma. The majority of patients may be managed with a VP shunt alone.
