Please verify term, "alternative". Chronic immune-mediated demyelinating polyneuropathy (CIDP) is a treatable immune-related demyelinating polyneuropathy. Approximately 20% of cases do not respond to first-line therapies; most of these cases are due to alternative diagnoses, although some of them are due to severe CIDP. Unfortunately, a lack of universally accepted diagnostic criteria complicates the course of diagnosis and treatment. This article discusses videos of cases referred to a tertiary medical center for "refractory CIDP" and pitfalls in the diagnosis and management of this condition.
