ABSTRACT Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an immune‐mediated peripheral neuropathy commonly defined by symmetric involvement of both proximal and distal muscles. This case report describes a rare presentation of acute‐onset CIDP in a 45‐year‐old woman with mixed connective tissue disease and myasthenia gravis. She experienced recurrent episodes of acute limb weakness along with cerebrospinal fluid pleocytosis. Comprehensive electrophysiological studies identified proximal amplitude reductions and temporal dispersion abnormalities, affirming the diagnosis of CIDP. Functional improvement was achieved with appropriate treatment including intravenous immunoglobulin.
