Selective downgaze paralysis was correlated with discrete bilateral lesions
at the mesencephalic-diencephalic junction in a 9-year-old girl following
severe pneumococcal meningitis, and in a 64-year-old man who suffered an
embolic infarction. Magnetic resonance imaging demonstrated bilateral
lesions in the region of the rostral interstitial nucleus of the medial
longitudinal fasciculus. Clinical-radiologic correlation allowed
identification of the likely vascular cause in both patients.
