13y FS Pug with central vestibular signs of 2‐day duration. There is a well‐delineated region of T1 hypointensity (a: arrow) and T2
hyperintensity (b,c: arrow) involving the right side of the cerebellum. The lesion has minimal mass effect and is not associated with other
intracranial lesions. The focal area of hyperintensity on the B 1000 diffusion image (d: arrow) and the corresponding region of hypointensity
on the apparent diffusion coefficient map (e: arrow) are attributable to diffusion restriction in the ischemic tissue. MR findings and
clinical signs are consistent with nonhemorrhagic cerebellar infarction caused by right rostral cerebellar artery thrombosis.
