    AbstractA 73-year-old man presented with muscle weakness and atrophy of his right arm. Atrophy of his left brachia and left calf had occurred 13 years before without any improvement or deterioration. His sister and cousin had a history of paralytic poliomyelitis. Serum poliovirus type 2 neutralizing antibody was elevated to 128×. Electromyography revealed chronic denervation potentials not only in the muscles affected previously but also in the unaffected muscles. Acute and chronic denervation potentials were found in the newly affected muscle. Postpolio syndrome should be considered in patients with unilateral muscular atrophy even when they have no history of paralytic poliomyelitis.
