Neurosarcoidosis : Initial Presentation and Disease Course

Neurosarcoidosis represents up to 10% of sarcoidosis cases. Little is known about its long-term course, even if the disease remains mainly monophasic with/w.o. sequelae, or if bouts of new symptoms may arise over years (polyphasic). Using retrospective data from patients diagnosed with neurosarcoidosis in three French referral centers for neuro-inflammation, the investigators aim to determine patterns of disease course, according to the initial presentation and the treatments used.
