Chronic inflammatory demyelinating polyradiculoneuropathy with NF155 antibodies (anti-NF155+) constitutes a specific chronic inflammatory demyelinating polyradiculoneuropathy subset with a high incidence of limb's tremor and poor response to conventional therapies. We report a patient with chronic inflammatory demyelinating polyradiculoneuropathy anti-NF155+ with a severe tremor involving limbs, head and voice that responded very well to rituximab. This response correlated with a sharp decrease in the anti-NF155 titers. This case is the first report associating head and voice tremor to chronic inflammatory demyelinating polyradiculoneuropathy, reinforces the hypothesis of the cerebellar origin of this tremor and provides indirect evidence that the antibodies may be the cause of the tremor in these patients.

Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) with anti-neurofascin-155 antibodies is a subgroup of CIDP with tremor and poor response to intravenous immunoglobulins. A 23-year-old male presented with a 6-month history ataxic-stepping gait, stocking tactile hypoesthesia, areflexia, tremor at limbs and tongue. Neurophysiology and cerebrospinal fluid analysis supported the diagnosis of CIDP. Tongue EMG was negative. Serum was positive for neurofascin-155 IgG4. His symptoms improved with intravenous methylprednisolone and then immunoglobulins, but not the tremor. Neurofascin-155 antibodies binding to cerebellar neurons suggests its central origin. This is the first neurofascin-155 antibody-seropositive patient with also tongue tremor, who is candidate to rituximab.
