Chronic inflammatory demyelinating polyneuropathy: A unique case of chronic disease with atypical features

We present a unique case of diffusely extensive Chronic Inflammatory Demyelinating Polyneuropathy (CIDP). Typically affecting the peripheral nervous system and manifesting with muscle weakness, breakdown or paresthesia, we present a case that additionally demonstrates; cranial nerve involvement, central nervous system parenchymal lesions, and chronic osseous remodeling of the nerve tracts. Cranial nerve involvement to this extent has only been described in one other case report to our knowledge. Central nervous system parenchymal lesions are extremely rare in CIDP and no discrete discussion about osseous remodeling has been presented, thus far, in the literature. The findings illustrated in this case may spur further understanding of imaging characteristics most associated with chronic CIDP disease and care measures that could help stratify patients most at risk for severe symptomologies.
