Summary
CT-guided stereotactic biopsy accurately diagnoses brain lesions, including glial tumors and abscesses. This minimally invasive technique is crucial for managing intra-axial lesions when surgery is not feasible.
Area of Science:
- Neurosurgery
- Neuroradiology
- Neuropathology
Background:
- Stereotactic biopsy is a minimally invasive neurosurgical technique.
- Accurate histological diagnosis is essential for guiding treatment of intracranial lesions.
Purpose of the Study:
- To evaluate the diagnostic accuracy and safety of CT-guided stereotactic biopsy.
- To assess the utility of stereotactic biopsy in managing intra-axial space-occupying lesions.
Main Methods:
- Retrospective study of 60 CT-guided stereotactic biopsies performed between April 1992 and April 1995.
- Analysis of diagnostic yield, complication rates, and specific pathologies encountered.
Main Results:
- Accurate histological diagnosis was achieved in 56 out of 60 cases (93.3%).
- Glial tumors (38 cases, mostly high-grade) and abscesses (5 cases) were the most common findings.
- Complications occurred in 5% of the procedures.
Conclusions:
- CT-guided stereotactic biopsy is a simple, accurate, and safe procedure for diagnosing intra-axial brain lesions.
- It is an indispensable tool for managing lesions where surgical resection is not an option.
- The study confirms the established role and efficacy of stereotactic biopsy in neuro-oncology and infectious disease management.
