咽喉頭浮腫を合併したムンプス感染症の1例

A case of mumps with laryngopharyngeal edema

はじめに

　流行性耳下腺炎はムンプスウイルスによる感染症であり，耳下腺の腫脹・疼痛や発熱を主症状とする。主に小児期に好発するが，成人発症も少なからず存在する。しばしば感音難聴や髄膜炎，睾丸炎などの合併症を生じるが，咽喉頭浮腫は比較的稀である。過去にも報告例があり^1〜20），特に顎下部の腫脹を伴う場合では注意が必要とされている。今回，ムンプスウイルス感染に伴う喉頭浮腫と呼吸困難をきたした症例を経験したので，若干の文献的考察を含め報告する。

　Epidemic parotitis is an infectious disease caused by the mumps virus. It is mainly seen in childhood and causes swelling of the parotid gland, pain, and fever. Complications such as sensorineural hearing loss, meningitis, and orchitis may occur, but laryngopharyngeal edema is rare. We report a case of mumps with laryngopharyngeal edema and dyspnea. An 26-year old woman presented to our hospital with dyspnea, swelling, and pain in the submandibular and subaural regions. Endoscopic examination showed significant laryngopharyngeal edema and airway narrowing. We decided to secure the airway by oral intubation. The patient was admitted to the hospital and treatment with intravenous steroids was started. The diagnosis of mumps was confirmed by an elevated serum antibody titer. In this report, we describe a case of laryngeal edema and dyspnea associated with mumps virus infection, including a discussion of the literature.
