A 62 year old-woman presented with vertigo, nausea and vomiting. Examination showed right sided ataxia, slurred speech, and nystagmus. |
| Inferior Cerebellar Infarction: Flair axial MRI. Note the bright signal in the inferior cerebellum, in the distribution of the posterior inferior cerebellar artery (PICA). Also note the swelling and compression of the cerebellum on the brainstem and fourth ventricle. Strokes in this location can be very serious, and result in death, if brainstem compression occurs or if the fourth ventricle is occluded and hydrocephalus develops. This constitutes a neurosurgical emergency, requiring immediate decompression. Strokes in this location are often misdiagnosed in the emergency room as gastroenteritis. |
