Summary
Cranial stereotactic radiosurgery (SRS) requires precise planning to avoid errors. Accurate outlining and neuroradiological collaboration are crucial for successful SRS treatment of brain lesions.
Area of Science:
- Neurosurgery
- Radiation Oncology
- Medical Imaging
Background:
- Stereotactic radiosurgery (SRS) has become a standard treatment for various intracranial lesions.
- A 17-year experience at the Royal Adelaide Hospital provided prospective data for this study.
- Over 250 SRS treatments were planned for benign and malignant intracranial lesions.
Observation:
- Five case studies involving meningioma, acoustic neuroma, brain metastases, and arteriovenous malformation were analyzed.
- Each case highlighted specific challenges and lessons learned in SRS planning and execution.
- The data were prospectively gathered over a 17-year period.
Findings:
- SRS demands meticulous accuracy in target outlining due to its highly conformal dose distribution.
- Geographic misses resulting from inaccurate outlining can have significant clinical consequences.
- Misdiagnosis, particularly of presumed brain metastases without histological confirmation, poses substantial risks.
Implications:
- Neuroradiological expertise and interdisciplinary collaboration are essential for optimizing SRS outcomes.
- The findings underscore the importance of precise imaging and diagnostic confirmation in SRS planning.
- Careful consideration of potential pitfalls can enhance the safety and efficacy of SRS for brain tumors and other lesions.
