Gangliogliomas in childhood

Area of Science:

• Neuro-oncology
• Pediatric Neurology
• Neurosurgery

Background:

• Ganglioglioma is a central nervous system tumor comprising dysplastic nerve cells and glial elements.
• It is a recognized cause of refractory epilepsy in pediatric patients.

Purpose of the Study:

• To present a series of pediatric patients with ganglioglioma.
• To evaluate the role of imaging and surgical resection in managing this condition.
• To correlate histological findings with patient outcomes.

Main Methods:

• Retrospective review of 12 pediatric patients (9 months to 15 years 9 months) with epilepsy.
• Utilized computed tomography (CT) and magnetic resonance imaging (MRI) for tumor localization.
• Assessed outcomes following complete or partial surgical resection.

Main Results:

• Epilepsy refractory to medical treatment was the primary presentation, lasting up to 8 years.
• Calcification was present preoperatively in 4 of 12 cases.
• The majority of patients experienced symptomatic relief after surgical resection.
• Histologically, 11 tumors had grade 1 astrocytic elements, and one had grade 2 areas.

Conclusions:

• Ganglioglioma should be suspected in children with long-standing, refractory epilepsy.
• Prognosis is linked to the astrocytic component; low-grade astrocytoma is associated with better outcomes.
• Surgical excision can lead to significant symptomatic improvement or cure in pediatric ganglioglioma cases.
