Neuroendoscopic approach to quadrigeminal cistern arachnoid cysts

Area of Science:

• Neurosurgery
• Pediatric Neurosurgery
• Minimally Invasive Surgery

Background:

• Quadrigeminal arachnoid cysts can cause hydrocephalus and intracranial hypertension in pediatric patients.
• Traditional surgical approaches may be invasive.
• Neuroendoscopy offers a minimally invasive alternative for treating these cysts.

Purpose of the Study:

• To report the outcomes of pediatric patients with quadrigeminal arachnoid cysts treated with neuroendoscopic fenestration.
• To evaluate the efficacy and safety of this minimally invasive technique.

Main Methods:

• Retrospective review of hospital records for three pediatric patients.
• All patients presented with hydrocephalus.
• Procedures included lateral ventricle-cystostomy and endoscopic third ventriculostomy using rigid neuroendoscopes.

Main Results:

• Three patients (one boy, two girls) aged 7 months to 14 years underwent the procedure.
• One patient had prior shunting.
• All patients experienced uneventful postoperative courses with no complications, resolution of intracranial hypertension symptoms, and significant cyst size reduction.

Conclusions:

• Neuroendoscopic fenestration is an effective and suitable treatment for quadrigeminal cistern arachnoid cysts.
• This technique successfully addresses accompanying hydrocephalus.
• It represents a safe and minimally invasive surgical option for pediatric patients.
