Summary
Linear accelerator (LINAC) stereotactic radiosurgery effectively treated a residual central neurocytoma. This advanced radiation technique led to complete tumor absence in long-term follow-up, suggesting its efficacy for similar cases.
Area of Science:
- Neurosurgery
- Radiation Oncology
- Oncology
Background:
- Central neurocytoma is a rare, typically benign brain tumor often treated with surgical resection.
- Recurrence or residual tumor after initial surgery can necessitate further treatment.
- Stereotactic radiosurgery offers a non-invasive approach for localized tumor management.
Observation:
- A patient with a residual central neurocytoma after craniotomy showed tumor growth on follow-up MRI.
- Linear accelerator (LINAC) stereotactic radiosurgery was administered to the residual tumor.
- The treatment involved a dose of 1750 cGy delivered with 3 isocenters.
Findings:
- Post-radiosurgery follow-up, including MRI scans up to 51 months, revealed complete absence of the residual tumor.
- No evidence of recurrence or residual disease was noted during the extended observation period.
- LINAC radiosurgery demonstrated complete tumor ablation in this case.
Implications:
- LINAC stereotactic radiosurgery is a viable and effective treatment option for residual or recurrent central neurocytoma.
- This case highlights the potential of precision radiation techniques in managing challenging neurosurgical cases.
- Further research into radiosurgery for central neurocytoma could refine treatment protocols and improve patient outcomes.
