Intramedullary cysticercosis.

An unusual case of intremedullary cysticerosis in a 22-year-old Mexican female is presented. The patient had a marked paraparesis with a D12 sensory level, absent deep tendon reflexes and no sphincteric disturbances. Pain in the spine was a prominent feature. A complete myelographic block opposite D12 proved at laminectomy to be due to a solitary cysticercus vesicle. It was removed from the conus medullaris through a right ventro-lateral myelotomy. The patient recovered.
