Acute Isolated Uvular Infarction

Cerebellar infarction presenting isolated vertigo

“…6,12 This finding can be explained by 1) mPICA supplies the nodulus and uvula, key components of the vestibulocerebellum with strong connections to the ipsilateral vestibular nuclei, 18,19 and 2) extremity cerebellar signs can be minimal or absent with mPICA territory cerebellar infarction particularly if the infarct is small. 6,9,[13][14][15] Surprisingly, a few patients with large mPICA territory infarcts (Patients 3, 13, 14, and 23) had no extremity ataxia.…”

“…5 Prior studies 6-15 of cerebellar infarction have described an uncommon clinical presentation with isolated spontaneous prolonged vertigo. However, most were case reports [6][7][8]11,[13][14][15] and there has been no large prospective study of patients with cerebellar infarction simulating VN. Thus, we sought to assess the frequency, the involved vascular territories of cerebellar infarction, and the pattern of clinical presentations of cerebellar infarction mimicking VN.…”
