Weber syndrome

Weber syndrome is a midbrain stroke syndrome that involves the cerebral peduncle and the ipsilateral fascicles of the oculomotor nerve 1-3.

It is usually caused by an ischaemic stroke, typically involving branches of the posterior cerebral artery 1-3.

Imaging may be helpful to connect the neurological symptoms with a single causative lesion.

The imaging appearance of Weber and Benedikt syndromes may be similar, as both result from insult to the oculomotor nuclear complex 1-3. (The latter syndrome is caused by compromise of the red nucleus in the midbrain tegmentum.)

The syndrome was first described by Sir Hermann Weber (1823-1918), a German-born English physician, in 1863 4.
