Neuroma of multiple nerves
Like all other cranial nerves mixed nerves (IX-Glossopharyngeal, X-Vagus, XI-Spinal Accessory, defined as "mixed" for the dual motor function/sensory) may be the site of origin of benign tumours that arise from their sheaths coating and are called neuromas or Schwannomas.
These tumours can develop along any stretch of the nerves; hence they can be located in the neck, inside the skull, or can be bilobed with a component in the neck, intracranially or within the jugular foramen. The neuromas of mixed nerves are quite rare, but in a place, they originate their surgical removal may result in significant postoperative deficits, especially if pre-operatively the patient is free of symptoms.
