Claude Syndrome. Severely motion degraded axial T2-weighted (a) and DWI (b) images of the midbrain demonstrate a subacute infarct within the left midbrain tegmentum, with extension from the Sylvian aqueduct to the red nucleus. This patient presented with downward abduction of the left eye and right leg incoordination with poor gait. The visual disturbance is related to the involvement of the oculomotor nerve fascicles. Injury to the dentato-rubro fibers and/or red nucleus resulted in ataxia.
