Resumo(s)
Background: Cavernous malformations arising in a single optic nerves paring the chiasm (intracranial prechiasmatic optic nerve) and expanding into the optic canal are extremely rare lesions. Published series or case reports regarding the surgical removal of these vascular malformations within this specific location are scarce.
Case description: We present the first case to be published, of an intracranial optic nerve cavernous malformation with a contiguous canalicular component that was totally and successfully removed through a microsurgical pterional approach with excellent clinical outcome.
Conclusion: This pathology should always be considered in the differential diagnosis of optic neuropathy and visual loss. Early detection and surgical proposal are mandatory, warranting the prevention of permanent damage to visual pathways. Radical resection is challenging, but usually curative and associated with favorable visual outcomes.
