Abstract

The introduction of computed tomography in the mid 1970s radically altered the practice of both neuroradiology and steteotactic neurosurgery. Shortly after the introduction of CT, work began on a variety of methods to guide biopsy instruments to brain lesions demonstrated on CT scan. And so, a prototype Brown-Roberts-Wells(BRW) CT stereotactic system was been available to us. We report its utilization in evaluation of less accessible brain lesions using BRW system; 22 superfical lesions including the motor cortex, 3 brain stem lesions, 5 parasellar lesions, 3 pineal lesions, 3 C-p angle lesions, 3 multiple lesions. There is one complication; intratumoral bleeding. There is no mortality in this series. The diagnostic rate is 88.9%. The indications of BRW of guidance stereotactic biopsy are considered as followings; 1) Adverse medical condition. 2) Highly malignant lesions. 3) Multiple lesions. 4) Lesions near by motor cortex. 5) Brain stem lesions. 6) Deep seated lesions. 7) Small sized lesions.
