ABSTRACT
Introduction: Detailed description of infarction of the midbrain is sparse likely due to the complex arterial supply of this region of the brain. Among the ventral midbrain syndromes reported is Claude syndrome. This syndrome caused majorly by a vascular insult to the ventromedial midbrain, characteristically presents with ipsilateral third cranial nerve palsy and contralateral hemiataxia. It is a rare syndrome and only a few cases have been reported since 1912 when it was first described by Henri Claude. Case presentation: 45-year-old male, who developed sudden onset dysarthria, right third cranial nerve palsy and left sided ataxia. An infarct in the right ventromedial midbrain was revealed on magnetic resonance imaging of the brain. Conclusion: We describe a case report of a middle-aged man with minimal vascular risk factors (ASCVD = 1.3%) for stroke, who presented with features suggestive of Claude syndrome.
