A case report of acute laryngitis with auricular lesion: Herpes zoster infection with isolated vagus nerve involvement and vocal fold paresis

초록

Acute laryngitis and acute inflammatory diseases of either infectious or non-infectious causes have similarities with herpes zoster of the vagus nerve (VHZ). We present a case which was initially diagnosis wtih acute laryngitis but finally diagnosed as VHZ. A 41-year-old male presented with an ongoing fever, throat pain and right otalgia lasting for two days with worsening symptoms despite nonsteroidal anti-inflammatory drug medication. Initially, he was treated conservatively as acute laryngitis was suspected. However, VHZ was subsequently diagnosed in this patient after considering unilateral auricular and laryngeal vesicles which were followed by ipsilateral vocal fold paresis. An antiherpetic agent and prednisolone were administered upon the presentation of vocal fold paresis. Axonotmesis was discovered by laryngeal electromyography one week after the appearance of vocal fold paresis. All symptoms subsided after one month. These results highlight the importance of understanding vagus nerve function in developing a differential diagnosis for laryngitis and VHZ.
