[2 cases of post-measles myelitis].

Two cases of a very rare complication of rubella i.e. a strictly spinal cord lesion developing during the course of the viral infection, are reported. In the first case, there was a flaccid paraplegia which incompletely regressed after two months. In the second case there were only sensory disorders and sphincter disturbances and recovery was complete after one month. The post-eruption encephalomyelitis lesions are of uncertain paphogenesis but the most common hypothesis suggested is that of a delayed hypersensitivity mechanism involving a cell-mediated immunologic reaction. The prognosis of these post-injection neurologic manifestations is difficult to assess, but spinal cord lesions could have a good prognosis.
