Cheirobuccal sensory syndrome.

Two patients presented with sensory impairments confined to their right intraoral cheek and right first three fingers. An objective decrease of pinprick pain was detected at these sites. Neuroimaging illustrated recent infarcts in the contralateral ventral thalamus of both patients. The intraoral and cheiral sensory impairments resolved within two months after onset. We coined the term ”cheirobuccal sensory syndrome” to describe these cases. The clinical significance and pathogenesis of this peculiar syndrome are discussed.
