Anterior biopercular syndrome caused by unilateral infarction.

The anterior biopercular syndrome is characterized by facio-pharyngo-glosso-masticatory diplegia, with automatic dissociation of movements. It generally translates bilateral opercular lesion, often of vascular etiology. There are very few cases described with unilateral lesions. We present the case of a patient with a bilateral anterior opercular syndrome caused by unilateral infarction.
