[Paralysis of the common oculomotor nerve and contralateral cerebellar syndrome (Claude's syndrome). 2 cases caused by mesencephalic infarction].

Two cases of Claude's syndrome due to a mesencephalic infarction in the territory of the interpedoncular fossa arteries are reported. The first case had pupillary sparing while ptosis was lacking in the second case. Partial impairment of the oculomotor nerve suggests an intra-axial fascicular organization. However, the precise intra-axial pattern of the nerve is unknown in humans.
