Occlusion of vertebrobasilar system in young adult is rare. A 18-year-old man presented with disturbance of consciousness. While the level of consciousness fluctuated in the acute stage, eventually he regained consciousness. Neurological examination disclosed hypesthesia of the right half including the right face, right facial palsy, dysarthria and right hemiplegia. CT and MRI showed ischemic lesions in the pons and superomedial region of the cerebellum on the left side. Initial VAG demonstrated the occlusion of left superior cerebellar artery (SCA) and bead-like stenosis of basilar artery (BA).<BR>Transient neurological deterioration correlated with the extension of ischemia or edema into the left inferior colliculus. Left posterior cerebral artery (PCA) as well as left SCA became occluded on the second VAG 3 weeks later.<BR>Neurological symptoms gradually improved. The 3rd VAG which was carried out 1 month from the onset confirmed the recanalization of left PCA and SCA, and almost normal posterior circulation was demonstrated in the 4th VAG another 1 month later. The latest MRI showed the ischemic lesions in the territories of left lateral pontine branch of BA and left SCA. Residual neurological deficits on discharge were mild cerebellar ataxia, dysarthria and right hemiparesis.<BR>The pathogenesis of this lesion was possibly attributable to idiopathic angiitis.
