Several diseases, nevertheless, may present similar features as CIDP. It is of paramount importance to recognize these mimics to yield an optimal therapeutic effect. Neuronal intranuclear inclusion disease (NIID) is a rare, progressive neurodegenerative disorder known for its diverse clinical manifestations. Since it may present as sporadic as well as inherited manner and may only involve the peripheral nerve system, it might resemble the clinical course of CIDP. Here, we report the case of a 61-year-old male who presented with subacute onset progressive paresthesia and weakness in lower extremities associated with gait disturbance. Nerve conduction studies demonstrated the features of demyelinating polyneuropathy with predominantly motor involvement. Under the impression of CIDP, immunomodulating therapy was given but with limited clinical response, prompting our consideration of seeking other diseases. Guided by characteristic magnetic resonance image findings during the second round survey, a diagnosis of NIID was confirmed by tissue and molecular pathologies. This is the first report in Taiwan to describe a patient with NIID who initially presented with clinical, electrophysiological, and laboratory features of CIDP, yet later confirmed to be NIID by tissue and molecular proof. Clinicians need to be aware of the possibility of NIID when diagnosing CIPD, especially if atypical presentation such as multi-system involvement or poor therapeutic responsiveness is present.<\/jats:p>","DOI":"10.4103\/ant.ant_113_0050","type":"journal-article","created":{"date-parts":[[2025,12,30]],"date-time":"2025-12-30T09:00:15Z","timestamp":1767085215000},"page":"239-244","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Neuronal Intranuclear Inclusion Disease Mimicking Chronic Inflammatory Demyelinating Polyradiculoneuropathy: A Case Report"],"prefix":"10.4103","volume":"34","author":[{"given":"Shih-Chieh","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Kaohsiung Armed Forces General Hospital, Kaohsiung, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi-Hao","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Neurology, Neurological Institute, Taipei Veterans General Hospital, Taipei, Taiwan"},{"name":"College of Medicine, National Yang Ming Chiao Tung University, Taipei, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shih-Yu","family":"Fang","sequence":"additional","affiliation":[{"name":"Department of Neurology, Neurological Institute, Taipei Veterans General Hospital, Taipei, Taiwan"},{"name":"College of Medicine, National Yang Ming Chiao Tung University, Taipei, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hsiang-Ting","family":"Hsu","sequence":"additional","affiliation":[{"name":"Department of Neurology, Neurological Institute, Taipei Veterans General Hospital, Taipei, Taiwan"},{"name":"College of Medicine, National Yang Ming Chiao Tung University, Taipei, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fu-Pang","family":"Chang","sequence":"additional","affiliation":[{"name":"Department of Neurology, Neurological Institute, Taipei Veterans General Hospital, Taipei, Taiwan"},{"name":"Department of Pathology and Laboratory Medicine, Taipei Veterans General Hospital, Taipei, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kang-Yang","family":"Jih","sequence":"additional","affiliation":[{"name":"Department of Neurology, Neurological Institute, Taipei Veterans General Hospital, Taipei, Taiwan"},{"name":"College of Medicine, National Yang Ming Chiao Tung University, Taipei, Taiwan"},{"name":"Department of Physiology, National Yang Ming Chiao Tung University School of Medicine, Taipei, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi-Chu","family":"Liao","sequence":"additional","affiliation":[{"name":"Department of Neurology, Neurological Institute, Taipei Veterans General Hospital, Taipei, Taiwan"},{"name":"College of Medicine, National Yang Ming Chiao Tung University, Taipei, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi-Chung","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Neurology, Neurological Institute, Taipei Veterans General Hospital, Taipei, Taiwan"},{"name":"College of Medicine, National Yang Ming Chiao Tung University, Taipei, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kuan-Lin","family":"Lai","sequence":"additional","affiliation":[{"name":"Department of Neurology, Neurological Institute, Taipei Veterans General Hospital, Taipei, Taiwan"},{"name":"College of Medicine, National Yang Ming Chiao Tung University, Taipei, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2025,12,30]]},"reference":[{"key":"R1-20251230","doi-asserted-by":"crossref","first-page":"3556","DOI":"10.1111\/ene.14959","article-title":"European Academy of Neurology\/Peripheral Nerve Society guideline on diagnosis and treatment of chronic inflammatory demyelinating polyradiculoneuropathy: Report of a joint task force-second revision","volume":"28","author":"Van den Bergh","year":"2021","journal-title":"Eur J Neurol"},{"key":"R2-20251230","doi-asserted-by":"crossref","first-page":"3170","DOI":"10.1093\/brain\/aww249","article-title":"Clinicopathological features of adult-onset neuronal intranuclear inclusion disease","volume":"139","author":"Sone","year":"2016","journal-title":"Brain"},{"key":"R3-20251230","doi-asserted-by":"crossref","first-page":"54","DOI":"10.1007\/BF00690510","article-title":"A light and electron microscopy study of an unusual widespread nuclear inclusion body disease.
