Tempaku A. A case of hemi facial spasm that resolved with the onset of Wallenberg syndrome. Int J Case Rep Images 2025;16(2):7–9.ABSTRACT
Introduction: A rare case of hemi facial spasm that disappeared with the onset of ipsilateral Wallenberg syndrome was observed.
Case Report: A 74-year-old woman had a left vertebral artery occlusion. The patient presented with left Wallenberg syndrome by a left medullo-lateral infarction. In addition, the left hemi facial spasm, from which had been suffered for last six months, disappeared.
Conclusion: The patient had ipsilateral vertebral artery occlusion. The occluded artery had caused the facial spasm with pulsatile stimulation against the root exit zone of VII nerve. Because of lateral area of medulla oblongata was perfused with contralateral posterior inferior cerebellar artery, ipsilateral medulla infarction had been left only slight neurological deficits. This report presents a fortunate case with anatomical and hemodynamic features.
Keywords: Hemi facial spasm, Posterior inferior cerebellar artery, Root exit zone, Vertebral artery, Wallenberg syndrome
