Benedikt syndrome, also called Benedikt's syndrome or paramedian midbrain syndrome, is a rare type of posterior circulation stroke of the brain, with a range of neurological symptoms affecting the midbrain, cerebellum and other related structures.

Ipsilateral third nerve palsy presenting with ptosis,abduction of eye.

Benedikt syndrome is caused by a lesion (infarction, hemorrhage, tumor, or tuberculosis) in the tegmentum of the midbrain and cerebellum.

It can result from occlusion of the posterior cerebral artery[1] or paramedian penetrating branches of the basilar artery.

[2] Deep brain stimulation may provide relief from some symptoms of Benedikt syndrome, particularly the tremors associated with the disorder.
