[Cerebral arteritis, carotid thrombosis and rubella: relation or coincidence?].

A 10 year-old boy presented with an acute transitory right hemiparesis with aphasia. On CT-scan there was a left temporal low density. The cerebral angiography showed a total obstruction of the left terminal internal carotid with a "beading" of the posterior cerebral artery on the same side. Blood serologies and the presence of specific IgM in the cerebrospinal fluid gave evidence for recent rubella. An other arteriogram after a follow-up of 3 months showed a persistent obstruction of the internal carotid but a disappearance of the cerebral posterior artery abnormalities.
