VALUE OF PARRASAGITTAL MAGNETIC-RESONANCE IMAGES IN VISUALIZING THE VASCULAR TERRITORIES OF THE CEREBELLUM

The outcomes of infarctions of the cerebellar arteries may range from self-limited neuro-ophthalmic symptoms to sudden death. Identification of the affected territory may assist in clinical management because t he vascular syndromes, as well as vascular mechanisms of cerebellar in farcts, are different according to the involved cerebellar arteries. H owever, it is usually difficult to tell the exact vascular territories using only transaxial imagings. Magnetic resonance imaging is a good tool for obtaining parasagittal and coronal images of the cerebellum, which are better for showing the vascular territories. To illustrate t his point we report a 61-year-old woman with bilateral cerebellar infa rcts (right posterior inferior cerebellar artery and left superior cer ebellar artery who had vertigo, vomiting, headache, intermittent verti cal diplopia, and difficulty walking. The clinical value of parasagitt al imaging of the cerebellum in this case is discussed.
