Stereotactic biopsy of brain tumours

Computerized tomography assisted Stereotactic biopsy technique using Leksell stereotactic frame was performed on 27 patients with small, multiple and deep seated brain tumours. There were 19 men and 8 women with an age range from 17 to 65 years. Histological diagnosis of 18 glial tumours, 9 non-glial tumours (5 colloid cysts, 4 metastatic lesions) was obtained. There was no mortality and minimal morbidity of 3.7%, histological diagnosis provided the information regarding differentiation from infectious and vascular lesions and grading of malignancy leading to logical guidance for therapeutic management of each lesion, confirming the value of stereotactic biopsy in brain tumours.
