Summary
This is the first reported case of bilateral cerebellopontine angle arachnoid cysts. Surgical intervention, including foramen magnum decompression, successfully resolved the patient's neurological symptoms.
Area of Science:
- Neurosurgery
- Neurology
- Radiology
Background:
- Arachnoid cysts (ACs) are rare, typically occurring as solitary lesions.
- Bilateral cerebellopontine angle (CPA) arachnoid cysts are exceptionally uncommon.
Observation:
- A 45-year-old female presented with progressive dysphagia, vertigo, and truncal ataxia.
- Magnetic resonance imaging confirmed bilateral CPA ACs with cerebellar tonsillar herniation into the foramen magnum.
Findings:
- Surgical excision of the right CPA AC was performed via a suboccipital approach.
- Foramen magnum decompression and duraplasty were integral parts of the intervention.
Implications:
- This case represents the first documentation of bilateral CPA ACs.
- Successful surgical management led to complete symptom resolution, highlighting the efficacy of combined cyst excision and decompression.
