Endoscopic endonasal resection of giant pediatric craniopharyngioma: impact on hypothalamic edema

Area of Science:

• Neurosurgery
• Pediatric Oncology
• Endocrinology

Background:

• Craniopharyngiomas are rare pediatric brain tumors often causing visual and hormonal deficits due to their location near critical midline structures.
• Compression of the optic chiasm and hypothalamus by these tumors can lead to severe visual impairment and endocrine dysfunction.

Purpose of the Study:

• To demonstrate the technical aspects of completely removing a pediatric craniopharyngioma via an endoscopic endonasal approach.
• To discuss the surgical outcomes, specifically visual recovery and resolution of hypothalamic edema, in pediatric patients.

Main Methods:

• A minimally invasive endoscopic endonasal approach was utilized for tumor resection.
• Surgical technique focused on complete tumor removal while preserving surrounding neurovascular structures.
• Postoperative assessment included ophthalmological evaluation and MRI to monitor for residual tumor and edema.

Main Results:

• Complete resection of the craniopharyngioma was achieved.
• The child experienced significant improvement in vision post-surgery.
• Extensive hypothalamic and optic radiation edema resolved completely within 5 days.

Conclusions:

• The endoscopic endonasal approach is a safe and effective method for treating pediatric craniopharyngiomas.
• This surgical technique facilitates rapid recovery of visual function and resolution of associated edema.
• Preservation of hypothalamic function is crucial and achievable with meticulous surgical technique.
