Case ReportsBrain stem cheiro-oral syndrome: neurological signs for brain stem lesions.
Cheiro-oral syndrome (COS) is characterized by a sensory disturbance in one hand and the ipsilateral oral corner. It is usually due to a lesion in the parietal cortex, thalamocortical projections or thalamus. Brain stem lesions may rarely produce COS. ⋯ In our patients, unilateral oculomotor nerve palsy or medial longitudinal fasciculus syndrome concurred with sensory disturbances of cheiro-oral distribution. COS produced by cortical/thalamic lesion is not accompanied with such oculomotor signs. Thus, oculomotor deficits are decisive in differentiating brain stem from cortical or thalamic COS.
