Large left cerebellar infarct involving the inferior posterior aspect of the cerebellum, the ipsilateral cerebellar tonsil and the lower part of the medulla oblongata (PICA territory). It appears as a large area of low signal on T1, high signal on FLAIR and T2 with restricted diffusion and no hemorrhagic component on the GE sequence. A mass effect is noted on the 4th ventricle.
Case Discussion
The clinical presentation and the MRI features are most consistent with a posterior inferior cerebellar artery (PICA) infarct.
