ICD-11 8A45.40 — Demyelination due to sarcoidosis

Neurosarcoidosis may manifest in many different ways, diagnosis may be difficult. Neurosarcoidosis can appear in an acute explosive fashion or as a slow, chronic illness. Any part of the central nervous system can be attacked by sarcoidosis but chronic neurosarcodosis can cause multiple cranial nerve palsies, parenchymatous cerebral involvement, hydrocephalus and encephalopathy or peripheral nervous system manifestations.
