The nervous system is affected in numerous patients. Peripheral nervous system (PNS) involvement may occur in as many as 67% of patients, typically later in the disease course. PNS manifestations include mononeuritis multiplex, sensorimotor polyneuropathy, and cranial nerve palsies.

Central nervous system (CNS) manifestations include vasculitis of small to medium–sized vessels of the brain or spinal cord and granulomatous masses that involve the orbit, optic nerve, meninges or brain. [50] Pituitary involvement with resulting hormonal dysfunction occurs about 1% of all cases of GPA, predominantly in women.
