 Case History | |  |
A 76-year-old man was consulted with sudden-onset perioral numbness over 6 h after percutaneous coronary interventions. Neurological examination revealed bilateral perioral light touch impairment, but no other focal neurological deficits were noticed. Brain magnetic resonance imaging and magnetic resonance angiography revealed an acute pontine infarction and no stenosis of related artery [Figure 1]. | Figure 1: (a) Diffusion-weighted magnetic resonance images of brain show a small pontine infarction.

Pure-sensory stroke in the pons, called cheiro-oral syndrome, is resulted in the involvement of various lesions of medial lemniscus and spinothalamic tract and sensory changes are more likely to become affected simultaneously.[1],[2] However, to the best of our knowledge, a case of isolated perioral sensory symptoms—not including finger (s) and hand—due to the bilateral medial lesion of medial lemniscus has not been reported. Neurologists should consider pontine infarction in patients with isolated perioral sensory changes, especially after procedure developed embolus.
