[Contribution of MRI to the topography of oculomotor disorders in multiple sclerosis].
Magnetic resonance imaging (MRI) was performed in 20 patients with multiple sclerosis and abnormal electro-oculographic examination. All but 2 patients showed MRI abnormalities in the infratentorial region: hypersignal on T2-weighted sequences and/or images of atrophy. Usually, each patient had multiple abnormalities, which could prevent anatomico-oculographic correlations. With oculomotor disorders of cerebellar origin, correlations between clinical findings and MRI images were satisfactory, but with disorders due to brainstem lesions correlations were not so good, as shown by the results in 9 patients with internuclear ophthalmoplegia.
