|Classification and external resources|
Claude's syndrome is a form of brainstem stroke syndrome characterized by the presence of an ipsilateral oculomotor nerve palsy, contralateral hemiparesis, contralateral ataxia, and contralateral hemiplegia of the lower face, tongue, and shoulder. Claude's syndrome affects occulomotor nerve,red nucleus and brachium conjunctivum
Cause and presentation
Claude's syndrome is caused by midbrain infarction as a result of occlusion of a branch of the posterior cerebral artery. This lesion is usually a unilateral infarction of the red nucleus and cerebral peduncle, affecting several structures in the midbrain including:
|dentatorubral fibers||contralateral ataxia|
|corticospinal tract fibers||contralateral hemiparesis|
|corticobulbar tract fibers||contralateral hemiplegia of lower facial muscles, tongue, and shoulder|
|oculomotor nerve fibers||ipsilateral oculomotor nerve palsy with a drooping eyelid and fixed wide pupil pointed down and out; probable diplopia|
It is very similar to Benedikt's syndrome.
