Axial T2WIs show multiple hyperintense lesions in the right cerebellum and medulla.
There is also increased signal in the lumen of the right vertebral artery (upper right image).
Left - Axial diffusion-weighted images reveal restricted diffusion in the cerebellar and
medullary lesions, which is consistent with cytotoxic edema.
Right (upper) – MR angiography shows no flow through the right vertebral artery.
Right (lower) – Axial fat-suppressed T1WI at the level of the foramen magnum shows increased signal
in the lumen of the right vertebral artery.
