Primary pulmonary meningioma is a rare benign tumor usually presenting as a solitary pulmonary nodule or mass. It can be easily misinterpreted as a primary lung tumor or metastases on imaging studies. We present a 54-year-old woman with an incidentally discovered solitary lung nodule, which was diagnosed as metaplastic primary pulmonary meningioma following resection. Metaplastic meningioma is a rare WHO grade 1 meningioma subtype with focal or global mesenchymal differentiation. To the authors' knowledge, primary pulmonary meningioma with mesenchymal differentiation has not been described previously in the English literature.
原发性肺脑膜瘤是一种罕见的良性肿瘤,通常表现为孤立性肺结节或肿块。它在影像学研究上很容易被误诊为原发性肺癌或转移瘤。我们报告了 1 例 54 岁女性,偶然发现孤立性肺结节,切除后诊断为骨化性原发性肺脑膜瘤。骨化性脑膜瘤是一种罕见的 WHO 1 级脑膜瘤亚型,具有局灶性或全身性间叶分化。据作者所知,此前在英文文献中尚未描述过具有间叶分化的原发性肺脑膜瘤。
