Abnormal electroneuromyography was observed in 11\/25 patients (44%), including eight isolated radiculopathies, one radiculopathy associated with polyneuropathy, one radiculopathy associated with sensory neuronopathy, and one demyelinating polyradiculoneuropathy. Cranial nerve involvement was observed in 18\/25 patients (72%). All patients except one had an associated CNS involvement. The first manifestation of the disease concerned the PNS in three patients. First-line immunotherapy was administered to 18\/24 patients (75%). The last follow-up modified Rankin Scale was\u2009\u2264\u20092 in 19\/23 patients (83%).
