Answer

Answer

This syndrome is due to obstruction of flow in the long circumferential branches of the basilar artery. This occlusion results in ipsilateral ataxia and coarse intention tremor (indicating involvement of the superior and middle cerebellar peduncles), weakness of mastication and sensory loss in the face (suggesting sensory and motor trigeminal nuclei and tracts), and contralateral loss of all sensory modalities (due to damage to medial lemniscus and spinothalamic tract) with or without facial weakness and hemiparesis (corticospinal tract).

Horizontal gaze palsy also may occur.
