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.
Characterization
It is characterized by the presence of an oculomotor nerve (CN III) palsy and cerebellar ataxia including tremor. Neuroanatomical structures affected include CNIII nucleus, Red nucleus, corticospinal tracts, brachium conjunctivum, and the superior cerebellar peduncle decussation. It is very similar in etiology, morphology and clinical presentation to Weber's syndrome; the main difference between the two being that Weber's is more associated with hemiplegia (i.e. paralysis), and Benedikt's with hemiataxia (i.e. disturbed coordination of movements).
Causes
Benedikt syndrome is caused by a lesion ( infarction, hemorrhage, tumor, or tuberculosis) in the tegmentum of the midbrain and cerebellum. Specifically, the median zone is impaired. It can result from occlusion of the posterior cerebral artery [1] or paramedian penetrating branches of the basilar artery.[2]
Treatment
Deep brain stimulation may provide relief from some symptoms of Benedikt syndrome, particularly the tremors associated with the disorder.[3]
