Abstract

A 75-year-old asymptomatic woman was admitted to our hospital after an abnormal shadow was found on a chest roentgenogram. Chest computed tomography showed a round mass in the right lower lobe. Magnetic resonance imaging showed the mass with high signal intensity on T2-weighted images and intermediate signal intensity on T1-weighted images. Fluorine-18-fluorodeoxyglucose-positron emission tomography showed high fluorine-18-fluorodeoxyglucose accumulation in the mass. A lobectomy was performed thoracoscopically. The pathologic diagnosis was cellular schwannoma. Immunohistochemical staining demonstrated the presence of S-100 protein, and the Ki67 labeling index was 12%. We present this case of intrapulmonary cellular schwannoma, which is extremely rare.

摘要

一位 75 岁无症状女性因胸片发现异常阴影而入院。胸部计算机断层扫描显示右下叶有一圆形肿块。磁共振成像显示肿块在 T2 加权图像上呈高信号强度，在 T1 加权图像上呈中等信号强度。氟-18-氟代脱氧葡萄糖正电子发射断层扫描显示肿块内氟-18-氟代脱氧葡萄糖摄取量高。行胸腔镜肺叶切除术。病理诊断为细胞性 schwannoma。免疫组织化学染色显示 S-100 蛋白阳性，Ki67 标记指数为 12%。我们报告了这例极为罕见的肺内细胞 schwannoma 病例。
