This procedure is used by neurosurgeons to obtain tissue samples of areas within the brain that are suspicious for tumors or infections.
The main indications for stereotactic biopsy are
- Deep-seated lesions
- Multiple lesions
- Lesions in eloquent areas of brain e.g. the motor cortex, basal ganglia, corpus callosum
- Very small lesion
- Lesions in a surgically poor candidate who cannot tolerate anaesthesia.
