[Ophtalmoplegia secondary to ponto-mesencephalic infarction : clinical-radiological correlation in the WEBINO syndrome].

Abstract

We report on a case of posterior midbrain stroke revealed by WEBINO ("Wall-Eyed Bilateral InterNuclear Ophthalmoplegia") syndrome, a relatively rare neuro-ophthalmological clinical entity combining bilateral internuclear ophthalmoplegia and exotropia. Encephalic MRI unraveled a bilateral paramedian ischemic lesion located at the posterior area of the ponto-mesencephalic junction, perfectly correlating to the theoretical localization of the medial longitudinal fasciculi. Clinical identification of this syndrome is key to efficiently guide MRI reading and proper management.
