Benedikt syndrome, or paramedian midbrain syndrome, is a midbrain stroke syndrome that involves the fascicles of the oculomotor nerve and the red nucleus.

Clinical presentation
- ipsilateral CN III palsy 1-4
- crossed hemiataxia 1-4
- crossed choreoathetosis 1-4
Pathology
It is usually caused by an ischemic stroke, typically involving branches of the posterior cerebral artery 1-4.
Radiographic features
Using imaging alone, it is difficult to distinguish Benedikt syndrome from Weber syndrome, unless clear involvement of the red nucleus can be identified, which is seen in the former 1-4.
History and etymology
The syndrome was first described by Moritz Benedikt (1835-1920), a Hungarian-Austrian neurologist, in 1889 5.
