👉 Crossostylis is a disease that affects the growth, development, and function of the blood vessels in the brainstem, specifically in the middle cerebral artery (MCA). It primarily results from an abnormality in the structure of this artery. This condition can lead to severe bleeding problems, including hemorrhages, which may affect the brain and other critical organs. Crossostylis is often associated with other conditions such as cerebral palsy or stroke, but it's not a specific diagnosis itself.
