[Lateral inferior pontine infarction: 2 clinical aspects].

Cases of lateral inferior pontine infarction are rare in the literature. We report two cases with MRI correlations. One involved the whole territory, the other the tegmental area only. Both also involved the middle cerebellar peduncle and one of them the adjacent lobules of the cerebellum. The first case emphasizes the classical alternate syndrome. The second case shows that acute vertigo mimicking a labyrinthine lesion can occur when involving the territory of the anterior inferior cerebellar artery.
