以深頸部感染表現之良性縱隔腔畸胎瘤－病例報告
Benign Mediastinal Teratoma Presenting as Deep Neck Infection - Case Report
摘要
良性縱隔腔畸胎瘤（benign mediastinal teratoma）並不常見，大多數的病患都是無意間由胸部X光發現，有症狀的病患則以胸痛最常見，可能同時伴隨有呼吸困難、咳嗽等症狀，而以深頸部感染的症狀來表現則相當罕見。本部有2000年經歷一名22歲男性病患，主訴前下頸部腫痛及輕微發燒，電腦斷層掃描顯示有一囊狀病灶自前下頸部往下延伸至前縱隔腔，經會診胸腔外科醫師採正中胸骨切開術（median sternotomy）將病灶切除。術後病理報告為成熟的畸胎瘤（mature teratoma）。病患在術後症狀完全消失，門診追蹤18個月沒有復發跡象。以深頸部感染來表現之良性縱隔腔畸胎瘤雖不常見，對於深頸部感染之病例，尤其是位於下頸部者，仍應考慮有前縱隔腔腫瘤侵犯至頸部之可能。
並列摘要
Benign mediastinal teratomas are not common and often discovered incidentally on routine chest radiographs. The most common symptoms, when present, are chest pain, cough and dyspnea. It is rare that a benign mediastinal teratoma presents as a deep neck infection. We presented a 22-year-old male with the chief complaints of anterior neck painful swelling and mild fever. The computed tomography scan revealed a cystic lesion over anterior mediastinum with superior extension to lower neck region. The removal of the tumor was achieved via a median sternotomy. Pathological examination showed a picture of mature teratoma. Anterior neck painful swelling resolved after operation and there was no evidence of recurrence during a follow-up period of 18 months. Although a benign mediastinal teratoma rarely invades the neck region, it should be considered in the work-up of a patient with deep neck infection, especially in the lower neck region.
