Summary
A patient with progressive ataxia experienced symptom relief after brainstem arachnoid cyst marsupialization. Recurrence was successfully managed using Teflon sponge, preventing further cyst regrowth and improving outcomes.
Area of Science:
- Neurosurgery
- Neurology
- Medical Imaging
Background:
- Intradural arachnoid cysts anterior to the brainstem can cause progressive ataxia.
- Surgical intervention is often required for symptomatic cysts.
Observation:
- A 50-year-old female presented with progressive ataxia due to a large anterior brainstem intradural arachnoid cyst.
- Initial marsupialization provided temporary symptom relief.
Findings:
- Cyst recurrence occurred nine months post-initial surgery.
- Re-evacuation combined with Teflon sponge placement in the cyst cavity and cisterna magna prevented recurrence over 25 months.
Implications:
- Teflon sponge placement is an effective adjunct in managing recurrent brainstem arachnoid cysts.
- This technique offers a durable solution for preventing cyst re-accumulation.
- Minimally invasive surgical strategies can significantly improve neurological outcomes.
