A primary pulmonary meningioma is an extremely rare entity. Primary pulmonary meningiomas manifested with a ground glass nodule are a very rare occurrence in clinical practice.
In this study, we report a case of a primary pulmonary meningioma with atypical computed tomography features. A 59-year-old Han Chinese female came to our hospital for treatment and reported that her physical examination revealed a ground glass nodule in the right lung for over 3 months. The histologic result revealed a primary pulmonary meningioma. The patient underwent a thoracoscopic lung wedge resection of the right upper lobe for a ground glass nodule. After 1 year of follow-up, the patient is still alive without evidence of metastasis or recurrence.
Primary pulmonary meningiomas could have a variety of radiological findings. As there are no specific radiologic features for the diagnosis of primary pulmonary meningiomas, complete resection of the lesion is required for both diagnosis and treatment. It is necessary to note the imaging features of primary pulmonary meningiomas, presenting as a ground glass nodule; this rare tumor should be considered in differential diagnoses.
原发性肺脑膜瘤极为罕见。临床上，以磨玻璃结节为表现的原发性肺脑膜瘤更为罕见。
本研究报告了一例具有非典型 CT 特征的原发性肺脑膜瘤。一名 59 岁汉族女性因体检发现右肺磨玻璃结节 3 个月余来我院就诊。组织学结果显示为原发性肺脑膜瘤。患者因右肺上叶磨玻璃结节行胸腔镜下肺楔形切除术。随访 1 年后，患者仍存活，无转移或复发迹象。
原发性肺脑膜瘤的影像学表现多样。由于原发性肺脑膜瘤的诊断没有特定的影像学特征，因此需要对病变进行完全切除，以达到诊断和治疗的目的。需要注意的是，原发性肺脑膜瘤的影像学特征为磨玻璃结节，在鉴别诊断时应考虑到这种罕见肿瘤。
