Summary
Surgical resection of interhemispheric arachnoid cysts is effective. This study reports three cases where cyst wall resection via the interhemispheric approach successfully treated these brain cysts.
Area of Science:
- Neurosurgery
- Neurology
- Pediatric Neurosurgery
Background:
- Interhemispheric arachnoid cysts are rare developmental malformations.
- These cysts can cause significant neurological deficits.
- Surgical intervention is often necessary for symptomatic cases.
Observation:
- Three patients with interhemispheric arachnoid cysts underwent surgical resection.
- Presenting symptoms included hemi-rigidity, gait disturbance, chronic headache, and tonic seizures.
- One case also involved agenesis of the anterior corpus callosum.
Findings:
- The interhemispheric approach allowed for effective resection of the cystic wall in all cases.
- Postoperative seizures occurred in two patients but were controlled with medication.
- Follow-up CT scans confirmed complete cyst resolution.
Implications:
- Simple resection of the cyst wall is a viable and effective surgical treatment for interhemispheric arachnoid cysts.
- The interhemispheric approach is a suitable surgical strategy for accessing these lesions.
- Early diagnosis and surgical management can lead to favorable outcomes.
