title: [Cerebral stereotactic biopsy and surgery: Report of 100 cases].
abstract: OBJECTIVE
  To report the results of the use of the stereotactic techniques in the management of intra cranial lesions.
  
  
  METHODS
  Between july 1994 and march 1998, we carried out 117 stereotactic procedures of whom only 100 cases were analyzed. All the procedures were achieved after a CT scan. Patients were separated in two groups: (A) stereotactic biopsy (91 patients), (B) surgery with laser guidance (9 patients). The mean age in group A was 38 years (2-75 years) versus 27 years (11-66 years) in group B. The sex-ratio was 1.3.
  
  
  RESULTS
  In the group A, the correct pathological diagnosis was obtained in 91.2% of cases. Glial tumors was the frequent histopathological variety of tumor (67.47%). Only one patient was operated after biopsy for a bilateral meningioma of the anterior 1/3 of the falx. There was only one death (1.09%) and 3.29% of transitory complications. In the group B, all patients were operated with laser guidance. Thirty seven per cent of patients underwent radiotherapy after the stereotactic biopsy or surgery.
  
  
  CONCLUSIONS
  Stereotactic biopsy is a reliable method for the histopathological diagnosis of deep-seated brain lesions. Surgery with laser guidance is a useful alternative for the management of small deep-seated lesions or lesions located in functional areas.
