Ti.: "High" vagus nerve lesions in varicella Zoster infection.

"High" vagus nerve lesions are rare and refer to the region of the nerve from the jugular foramen through the branching of the auricular (Arnold's branch) and the pharyngeal branch. Rapid onset of vagus nerve palsy is observed predominantly in trauma, and rarely in inflammation. An insidious onset points to a neoplastic cause. The acute "high" vagus nerve lesion is characterized by a unilateral paralysis of the recurrent laryngeal nerve, an incomplete paresis of the soft palate and a transient inability to swallow. This is a case description of a 79-year-old woman who presented with painful swelling of the left ear and occipital headache, followed by inability to swallow for 3 weeks. A markedly elevated Varicella Zoster titer suggested a herpes virus infection.
