What is a medulla stroke?

Wallenberg syndrome is a rare condition in which an infarction, or stroke, occurs in the lateral medulla. The lateral medulla is a part of the brain stem. Oxygenated blood doesn’t get to this part of the brain when the arteries that lead to it are blocked. A stroke can occur due to this blockage.

What is Weber’s syndrome?
