Stereotactic frame-based biopsy of infratentorial lesions via the suboccipital-transcerebellar approach with the Zamorano-Duchovny stereotactic system—a retrospective analysis of 79 consecutive cases
To analyze the diagnostic yield and safety of the suboccipital-transcerebellar approach for stereotactic biopsies of posterior fossa lesions, highlighting its significance in clinical practice.
Key Findings:
High diagnostic success rates for posterior fossa lesions (80-95%), indicating the approach's effectiveness.
The suboccipital-transcerebellar approach minimizes risk to healthy brain tissue, making it a preferred method.
Higher complication rates compared to biopsies in supratentorial areas, necessitating careful patient selection.
Interpretation:
Frame-based stereotactic biopsies are essential for accurate diagnosis of posterior fossa lesions, especially given the limitations of radiological diagnostics, and this study adds valuable data to the existing literature.
Limitations:
Retrospective design may introduce selection bias, affecting the reliability of the findings.
Single-center study may limit generalizability, suggesting the need for multi-center studies.
Conclusion:
The suboccipital-transcerebellar approach is a safe and effective method for obtaining tissue from infratentorial lesions, supporting its continued use in clinical practice, while further studies are needed to validate these findings.
