[Opercular syndrome of vascular aetiology].
BACKGROUND
Facio linguo masticatory paralysis resulting from bilateral lesion of the anterior opercular region, known today as Foix Chavany Marie syndrome, appears very frequently in adult patients as a consequence of generally ischemic vascular lesions, which directly affect the Rolandic opercula or the subcortical area surrounding them. However, forms that are secondary to infections, neoplasias and even unilateral lesions have been reported.


METHODS
Female patient, aged 70, with unknown auricular fibrillation, which started suddenly with right faciobrachial paresis secondary to a left striated ischemic infarction. Approximately 24 hours after beginning intravenous heparinization, the patient presents anarthria, facial hypomimia without asymmetries, dysphagia above all for liquids and bilateral lingual paresis. Extraoccular movements, blinking and corneal reflex were normal. Understanding of spoken and written language was maintained and there were no apraxias or agnosias. Neurological exploration was compatible with an opercular syndrome (OS). Urgent brain CT revealed the existence of a right cortiico subcortical temporal haemorrhage, in addition to the prior contralateral ischemia. The association of both lesions, ischemic and haemorrhagic, mirrored, justified all the symptomatology.


CONCLUSIONS
Anterior OS is characterised by a bilateral voluntary central paresis of the muscles innervated by the 5th, 7th, 9th, 10th and 12th cranial pairs with preservation of emotional or automatic mobility. Underlying mechanisms are also discussed.
