Paediatric cavernous malformation of the trigeminal nerve: Case report and review of the literature.

Cerebral cavernous malformations within the intracranial portion of the trigeminal nerve are rare. We discuss the first reported case presenting in a child, who was successfully treated with microsurgical resection, and review the published literature. This rare diagnosis should be considered in the differential diagnosis of mass lesions arising in the region of the trigeminal root entry zone. Surgical resection is recommended to prevent neurological deterioration and can produce a significant improvement in symptoms.
