Stereotactic biopsy is carried out for symptomatic lesions in the brain parenchyma when diagnostic clarification is important. This particularly applies to lesions that are inaccessible for resection, or when a type of tumor is suspected that requires a treatment other than surgical resection.
Stereotactic biopsy is a minimally invasive procedure with several advantages.
- Low morbidity and mortality
- Avoidance of a major operation involving opening the cranium
- Cost savings
- Fewer bed-days in the hospital
- To establish a diagnose in order to evaluate further treatment
