縦隔巨大迷走神経鞘腫の1例

Mediastinal Giant Vagal Nerve Schwannoma；Report of a Case

はじめに　超音波内視鏡下穿刺吸引法（EUS-FNA）で確定診断を得た縦隔発生巨大迷走神経鞘腫に対する手術を経験したので，文献的考察を加えて報告する．

A 73-year-old man visited his family doctor with complaints of cough and breathlessness. Right pleural effusion was detected by chest X-ray. Computed tomography （CT） showed a huge mass 13×11 cm in the right mediastinum along with right pleural effusion and atelectasis of the right middle and lower lobes. Surgery was performed 4 days after admission. Although the tumor was huge, it could be successfully removed. The symptoms improved and the patient was discharged after 10 days of surgery. Pathological examination revealed vagal nerve schwannoma with no malignant features.
