Two cases of Avellis syndrome and literature review

Avellis syndrome is a rare medullary syndrome.The main symptoms are paralysis of the ipsilateral soft palate and laryngopharyngeal muscles and superficial sensory disturbance on the contralateral side.Avellis syndrome is common in patients with medullary infarction.The lesions are mostly located in nucleus ambiguus and lateral spinal thalamus,and stenosis or occlusion of the intracranial segment of vertebral artery is the most common cause.In this article,the authors reported 2 cases of Avellis syndrome caused by medullary infarction,and retrospectively analyzed clinical data of 12 cases of Avellis syndrome reported in domestic literatures.Clinical characteristics,imaging manifestations,etiology,treatment and prognosis of these cases were analyzed and summarized,so as to improve clinicians′understanding of Avellis syndrome.
