FIG 1. Symptomatic stenosis of the right CA in a 62-year-old man.

A, Preprocedural DW MR image (6000/103/1) shows a preprocedural lesion in the cortical territory of the MCA (white arrow).

B, Preprocedural T2-weighted MR image (5700/119/1) shows no lesions in the cerebellar hemisphere in C.

C, Postprocedural DW MR image (6000/103/1) shows the preprocedural lesion in the cortical territory of the MCA and a new ipsilateral lesion (<10 mm) in the right cerebellar hemisphere (white arrow).

D, Postprocedural T2-weighted MR image (5700/119/1) obtained at a corresponding level shows the lesion in the cerebellar hemisphere in C (white arrow).

E, T2-weighted MR image 6 months after the procedures shows the persistent area of hyperintensity (white arrow).
