Cheiro-Oral syndrome due to Acute Lacunar Thalamic Infarct

A brain infarct is a tissue death due to inadequate blood supply to the affected area. While large or massive infarcts present with a very vague motor symptom, small thalamic infarcts can present with a variety of sensory deficits that can be difficult to diagnose clinically because of their seemingly disconnected manifestations. Cheiro-oral Syndrome is a pure sensory deficit which is confined to the perioral region and ipsilateral distal fingers. This very subtle clinical presentation might be missed in acute settings. We are reporting a case of a 46-year-old who was admitted with the complaints of peri-oral numbness on right side associated with weakness in right upper limb and lower limb.
