Hemimedullary syndrome

Hemimedullary syndrome, also known as Reinhold syndrome, occurs as a result of the occlusion of the ipsilateral vertebral artery proximal to the posterior inferior cerebellar artery and its anterior spinal artery branches 1-3. This situation causes lateral medullary infarct and medial medullary infarct simultaneously 1-3.


In many texts this syndrome is incorrectly named Babinski-Nageotte syndrome, however, this is a very similar yet clinically distinct syndrome 3.

History and etymology

The syndrome was first described by Heinrich Reinhold, a German physician, in 1894 4.
