Info
There is a large left cerebellar infarct involving the posterior inferior cerebellar artery (PICA) territory seen as a large area of low signal on T1, high signal on T2 and FLAIR with restricted diffusion. A mass effect is noted on the 4th ventricle with moderate dilatation of the 3rd and lateral ventricles. On MRA 3D-TOF the right PICA is well-visualized arising from the vertebral artery while the left is not visualized.
