title: [Total removal of hypothalamic glioma 15 years after irradiation of right optic glioma].
abstract: Hypothalamic glioma was found in a 17 year old male patient 15 years after irradiation of right optic glioma. It was totally removed by surgery. He was first admitted to Ryukyu University Hospital at the age of 1 year and 11 months, with right exophthalmos and visual disturbance. Diagnosis was anterior type of right optic glioma. This was treated by irradiation (47 Gy). Follow-up CT scans revealed no regrowth in intraorbital and intracranial regions. At the age of 17 years, CT scan and MRI showed an enhanced mass in the hypothalamus above the suprasellar cistern. Total removal was performed by bifrontal interhemispheric trans-lamina terminalis approach. Histological diagnosis was pilocytic astrocytoma. Postoperatively, consciousness remained disturbed for 3 weeks because of infarction in the bilateral medial nucleus of the thalamus. Radical excision of hypothalamic glioma was reviewed in the literature. We concluded that such excision has a potentially good outcome, and should be attempted when circumstances indicate its feasibility.
