[Progressive chronic rubella encephalitis. Report of a personal case (author's transl)]

This is a report on a now alive, 18 years old boy. He was affected by a progressive encephalitis which began between 7 and 12 years of age. The first signs were walking disorders and mental regression. The disease which developed during a few years led to a bed-ridden state and advanced mental deficiency. Strong biological arguments (analysis of the cerebrospinal fluid, virological study, brain biopsy) and comparison with several similar cases published before leading to the conclusion of rubella origin of this encephalopathy, despite of the absence of known history of congenital or acquired rubella in our case.
