Cerebellopontine angle lesions in children

Area of Science:

• Pediatric Neurosurgery
• Neuro-oncology
• Cerebellopontine Angle Lesions

Background:

• Cerebellopontine angle (CPA) lesions represent 5-10% of adult intracranial tumors but are rare in children (1%).
• Understanding pediatric CPA lesion management is crucial due to their infrequent occurrence.

Purpose of the Study:

• To review the management and outcomes of pediatric CPA lesions.
• To analyze the characteristics and treatment strategies for CPA lesions in children.

Main Methods:

• Retrospective review of pediatric patients with CPA lesions from 1988-2003.
• All patients underwent retrosigmoid suboccipital craniotomy and microsurgical resection.

Main Results:

• 30 children presented with 33 CPA lesions, predominantly on the left side (82%).
• Gross total removal was achieved in 12 cases, subtotal in 18.
• Outcomes included no sequelae (10), mild deficit (10), severe deficits (3), and mortality (7).

Conclusions:

• Pediatric CPA lesions are rare, with a left-sided predominance.
• Benign lesions are more common, and schwannoma is frequent, though histology varies.
• Microsurgical resection is the primary treatment modality for pediatric CPA lesions.
