Pseudohypertrophic myopathy in cysticerosis.
A patient with diffuse involvement of the central nervous system and pseudohypertrophic muscular changes induced by cysticerci is described. Electromyographic and pathologic changes are reported for the first time. Electromyographic examination demonstrated numerous short-duration, low-amplitude motor unit potentials in proximal muscles. Biopsy showed swelling of muscle fibers, fiber atrophy with fibrosis, and cellular infiltration separate from inflammatory exudate surrounding numerous cysts.
