Claude's Syndrome describes a stroke in the mid-brain affecting dorso-lateral structures. A branch of the posterior cerebral artery is occluded, leading to unilateral infarction of a cerebral peduncle and a red nucleus.
Claude's Syndrome is clinically characterised by:
- ipsilateral Horner's syndrome
- contralateral hemiplegia
- contralateral sensory loss - face and limbs
- if lower midbrain involved - ipsilateral cerebellar deficit
