頸部交感神経鞘腫の1症例—術前・術中診断の重要性とHorner症候について

Cervical Sympathetic Neurinoma:A Case Report

　はじめに

　頸部交感神経節由来の神経鞘腫はまれな疾患で，術後に頸部交感神経欠落症状である不快なHorner症候を生じる。今回われわれは最近経験した症例を若干の文献的考察を交えて報告する。

A case of neurinoma thought to be originated from the superior sympathetic ganglion in a 34-year-old woman presented with a right subauricular mass was reported. Examinations revealed the mass located in the parapharyngeal space with neur-inomatous feature. Operation proved the tumor from the superior sympathetic ganglion. His-tological diagnosis was neurinoma. The tumor was simply removed without reconstruction of the nerve. Ipsilateral Horner's signs were observed postoper-atively. Three months after the operation, miosis was still persisting.
