[A case of chronic inflammatory demyelinating polyradiculoneuropathy presenting recurrent attacks associated with pregnancies].

At 37 years of age, the patient initially presented with symptoms of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) during her 1st pregnancy. She was treated with intravenous immunoglobulin (IVIg), and showed favorable recovery, becoming almost asymptomatic by the age of 38. At 39 years of age, during her puerperal period of her second pregnancy, she developed symmetrical muscle weakness and sensory disturbance of the upper and lower limbs. Nerve conduction studies revealed diffuse demyelination of peripheral nerves, and she was diagnosed with recurrence of CIDP. Once again, she showed remarkable improvement after IVIg therapy, and she has remained asymptomatic without the induction of preventative therapies. Recurrence of CIDP triggered in accordance with multiple pregnancies is extremely rare, and its clinical and electrophysiological features are presented in this report.
