Description
Sarcoidosis can affect any part of the nervous system. It is estimated that about 5-15% of cases develop evidence of central nervous system involvement. 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 neurosarcoidosis can cause multiple cranial nerve palsies, parenchymatous cerebral involvement, hydrocephalus and encephalopathy or peripheral nervous system manifestations.
