Introduction:
Cranial nerve lesions can be secondary to a space-occupying lesion of the skull base compressing adjacent nerves.
Case Report:
We report the case of an 84-year-old man, who presented with rapid and concomitant onset of dysphagia and ipsilateral recurrent laryngeal nerve paralysis, suggesting an isolated lesion of the vagus nerve. MRI revealed a diagnosis of previously unknown clival meningocele.
Discussion:
Unilateral vagus nerve paralysis constitutes an exceptional mode of presentation of meningocele. Only a few isolated cases of clival meningocele have been reported to date, with no cranial nerve repercussions. The symptomatic management adopted in this case allowed rapid improvement of the patient's disorders.
