Primary pulmonary meningioma (PPM) is a very rare and mostly benign disease. Although PPM is incidentally detected as a solitary pulmonary nodule on X-ray or chest computed tomography, it does not have unique radiological characteristics; thus, it is difficult to differentiate it from other lung tumors. A healthy 54-year-old man visited our hospital because of multiple variable-sized lung nodules. He had no contributive medical history and no abnormality that was suggestive of extrapulmonary malignancy. Video-assisted thoracoscopic wedge resection was undertaken for diagnosis, and the tumor cells were histopathologically confirmed as PPM. Brain magnetic resonance imaging revealed no intracranial tumor. The patient has been well and without any progression of the remaining lesions over 24 months. Here, we present the clinicopathological features of this case in which the patient's nodules were mistaken for multiple metastatic lung nodules.
原发性肺脑膜瘤（PPM）是一种非常罕见且多为良性的疾病。尽管 PPM 偶尔会在 X 光或胸部计算机断层扫描中被发现为孤立性肺结节，但它没有独特的影像学特征；因此，很难将其与其他肺部肿瘤区分开来。一名 54 岁健康男性因多个大小不一的肺结节就诊于我院。他无相关病史，也无提示肺外恶性肿瘤的异常表现。为明确诊断，我们采用电视辅助胸腔镜楔形切除术，病理组织学证实为 PPM。脑磁共振成像未显示颅内肿瘤。患者情况良好，24 个月后未见其余病变进展。在此，我们报告了该病例的临床病理特征，患者的结节曾被误诊为多个转移性肺结节。
