[Raeder paratrigeminal neuralgia as expression form of intracavernous giant aneurysm]. / Nevralgia paratrigeminal de Raeder como forma de expressão de aneurisma gigante intracavernoso.

ABSTRACT

The authors report the case of a 50-year-old female patient with right orbital headache secondary to a giant intracavernous aneurysm, diagnosed as Raeder paratrigeminal neuralgia. The patient was surgically treated with internal carotid artery trapping together with brain revascularization (superficial temporal artery to a deep branch of the middle cerebral artery). The patient had an excellent outcome. The identity of the syndrome and the differential diagnosis are discussed based on literature review.
