title: [Image guided stereotactic approach of central nervous system lesions: accuracy, morbidity, mortality].
abstract: We studied seventy-five patients with brain lesions biopsied by stereotaxis from March 1993 to December 1998 at Universidade Federal de São Paulo-Escola Paulista de Medicina. The three most frequent lesions were: metastasis, low grade astrocytomas and glioblastoma multiforme. The morbidity rate was 2.66% due to: one case of scalp infection in a patient with thalamic cyst; and a partial seizure during surgery in a patient with lymphoma. The mortality rate was 1.33% due to increasing of cerebral edema after biopsy and the patient died after one week. The diagnostic accuracy was 89.33%.
