Stereotactic biopsy of deep brain tumors in infancy and childhood

In 17 patients. 2-16 years old, the clinical and neuroradiological data were unable to give clear-cut information regarding the histology of deep brain neoplasms. The lesions were located within the brain stern in two cases, in the pineal region in two cases, within the third ventricle in two eases, in the seller and parasellar area in three eases, in the basal ganglia and thalamic region in seven cases, and in the fmnlo-eallosal region in one case. In these patients, serial stereotactic biopsies were performed with the guidance ofCT scan in order to assess the nature and the real boundaries of the growths. The choice between conservative or surgical treatment was made after the established histological findings became available. The operative technique of stereotactic biopsy is briclly described and the value of this method is stressed in the treatment of brain tumors in children.
