| Abstract: | In its typical presentation, chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) occurs more often in old males as a progressive/recurrent motor and sensory nerve dysfunction with tendon areflexia. However, CIDP has also atypical clinical presentations, including pure sensory neuropathies, among which chronic immune sensory polyradiculopathy (CISP) accounts for only 0.5% of all CIDP, with no juvenile cases reported as yet. A 17-year-old girl presented for a progressive sensory ataxia and hands clumsiness. Diffuse tendon areflexia and hypokinaesthesia were observed. Motor and sensory nerve conduction studies were normal. F-waves were normal in median nerves and elongated in tibial nerves. H-reflex and somatosensory evoked potentials (SSEP) were absent. CSF normal cellularity with hyperproteinorrachia was found. Paraneoplastic, metabolic, and paraproteinemic neuropathies were excluded. A diagnosis of CISP has been made based on the presence of pure sensory symptoms in a polyneuropathic distribution, normal peripheral nerve conduction studies, and two supportive criteria (SSEP and CSF). Our paper describes the first CISP case in the pediatric age. We confirm SSEP and CSF as useful complementary tests for this diagnosis also at this age and suggest that clinicians should consider CISP in the spectrum of sporadic sensory ataxias of the pediatric age. We also suggest that in the presence of normal F-wave and peripheral motor nerve conduction, an absent H-reflex can further substantiate SSEPs in the diagnosis of CISP. Intravenous immunoglobulins were rapidly effective and safe. [ABSTRACT FROM AUTHOR] |
