A relapse of chronic inflammatory demyelinating polyradiculopathy was diagnosed in a 57-year-old man on the basis of progressive leg weakness, numbness, and urinary incontinence of approximately 1 week’s duration. He was treated at another hospital with oral prednisolone (60 mg/d). He was also being treated with aspirin (81 mg/d) for atherosclerotic disease. Three days before admission to our hospital, he fell and had a contusion on the left side of his lower back. The diagnosis of chronic inflammatory demyelinating polyradiculopathy was confirmed by electromyography. Intravenous immunoglobulin was administered, and the prednisolone was slowly tapered. During this hospitalization, aspirin therapy was continued. Also, subcutaneous heparin sodium (5000 U) was administered twice daily to prevent deep venous thrombosis.
