Clinical presentation
Cestan-Chenais syndrome is considered an intermediolateral medullary syndrome, which includes most features of the lateral medullary syndrome except ipsilateral hemiataxia, but also having contralateral hemiparesis/hemiplegia 1,2.
Pathology
It is likely that the most common cause of Cestan-Chenais syndrome is a posterior circulation ischemic stroke 1.
Radiographic features
Lesions are in the medulla with imaging characteristics dependent on the underlying cause.
History and etymology
The syndrome was named after French physicians Étienne Jacques Marie Raymond Cestan (1872-1934) and Louis Jean Chenais (1872-1950) who described the entity in 1903 3.
