Abstract:
Primary pulmonary meningiomas (PPMs) are rare meningothelial proliferation that lacks characteristic imaging findings, making their distinction from other peripheral lung tumors challenging. Therefore, surgical resection is often performed for the diagnosis and treatment of PPM. Herein, we describe a surgical case of PPM that grew over 10 years. A 63-year-old woman was referred to our department due to right middle lobe lung tumor enlargement. No significant symptoms were observed. Chest computed tomography revealed a tumor in the middle lobe of the right lung. F-18 fluorodeoxyglucose positron emission tomography showed accumulation in the nodule; thus, lung cancer could not be ruled out. Therefore, the preoperative differential diagnosis was cStageIB lung cancer. A right middle lobectomy was performed, and a histopathology examination revealed meningioma. There were no primary lesions in the head and whole spine magnetic resonance imaging, thus, a final diagnosis of PPM was made. Cautious observation is required postoperatively due to the possibility of recurrence.
Insights
Primary pulmonary meningiomas (PPMs) are rare lung tumors that are difficult to diagnose. This case study details a 10-year growth of a PPM, highlighting the need for surgical resection and careful postoperative monitoring.
Area of Science:
- Pulmonology
- Neurosurgery
- Oncology
Background:
- Primary pulmonary meningiomas (PPMs) are rare tumors originating from meningothelial cells within the lung.
- PPMs present diagnostic challenges due to nonspecific imaging findings, often mimicking lung cancer.
- Surgical resection is typically required for definitive diagnosis and treatment.
