Glioependymal cyst on the third cranial nerve: case report

Area of Science:

• Neuroscience
• Neurosurgery
• Pediatric Neurology

Background:

• Glioependymal cysts are rare, congenital, benign brain lesions.
• Lack of standardized classification leads to confusion in literature.

Observation:

• A 2-year-old female presented with a large exophytic glioependymal cyst in the left cerebral peduncle.
• Deteriorating function of the left third cranial nerve (CN III) was the primary symptom.

Findings:

• Successful microsurgical complete excision of the cyst via a fronto-orbitozygomatic approach.
• Complete recovery of the patient's CN III function within 3 months post-surgery.

Implications:

• Highlights the efficacy of surgical management for glioependymal cysts.
• Underscores the need for further research into the origin, classification, and common locations of these cysts.
