Abstrakt:	Pontine warning syndrome (PWS) is a condition characterized by crescendo transient ischemic attacks due to pontine ischemia. The reported case described a 72-year-old woman who presented repetitive sudden episodes of double vision, impaired balance, slurred speech and right-sided weakness. Neurological deficits lasted a few minutes-hours and disappeared during the first seven days after onset. On the 1st day, MRI revealed acute left paramedian pontine infarction with focal swelling. Supra-aortic vessel imagining revealed bilateral internal carotid stenosis of 50%; hypoplasia of the left vertebral artery. On the 7th day, MRI showed a tissue swelling reduction, and from that day, she had no symptoms. These clinical and radiological features were suggestive of PWS. Our patient presented a particular vascular pattern that could favour symptoms fluctuation. We performed a close MRI follow up and it allowed us to observe a clinical stabilization in association with edema reduction. Competing Interests: The authors declare no conflict of interest.
