Title
Unilateral perioral and thumb numbness - Cheiro-Oral Syndrome secondary to acute left thalamic infarct (E-Poster Presentations)
Subject
Cheiro-Oral Syndrome, acute left thalamic infarct
Description
Introduction
Cheiro-Oral Syndrome (COS) is a rare form of lacunar stroke characterized by pure sensory impairment, typically affecting the
perioral region and fingers.
Case Presentation
A 61-year-old male presented to the emergency department with a one-day history of numbness over the upper and lower lips on
the right side and the tip of the right thumb. He had no other neurological deficits or systemic symptoms. His medical history
included type 2 diabetes mellitus, hypertension, hyperlipidemia, lung cancer, prostate cancer, and brain metastases. A year prior,
he had a similar presentation on the left side, associated with cerebral metastasis. During the current presentation, neurological
examination revealed reduced sensation in the right perioral area and right thumb. Blood investigations showed a deranged lipid
profile. CT head imaging revealed a small hypodensity in the left thalamus, which MRI confirmed as a small acute infarct. He was
admitted, started on aspirin, and referred to the stroke team.
Discussion
COS is a rare and often overlooked pure sensory stroke. It is typically caused by lacunar infarcts in the thalamus, pons, medulla
oblongata, or cortex. This case highlights the importance of recognizing the symptoms of COS, performing neuroimaging, and
ensuring appropriate management and disposition in emergency settings.
Conclusion
Awareness of COS among emergency physicians is crucial for prompt diagnosis and management, which can significantly impact patient outcomes
