A 53 year-old man presented with vertigo, nausea and vomiting. Two days later, he became drowsy with gasping respirations. |
| Inferior Cerebellar Infarction: Flair axial MRIs. Note the bright signal in the right inferior cerebellum, in the distribution of the posterior inferior cerebellar artery (PICA). Also note that there is compression of the adjacent 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. |
