INTRODUCTION
Meningiomas are the most commonly encountered intracranial tumors, usually showing indolent behavior. Extra-axial spreading and distant metastases are seldom detected in these tumors, and lung metastasis from a low-grade meningioma is a rare event.
CASE PRESENTATION
This case report aimed to present the clinical, imaging, and pathological features of a 37-year-old Caucasian pregnant woman with bilateral lung metastases incidentally detected during preoperative workup ahead of surgery for a primary intracranial meningioma. The possible metastatic routes and risk factors of dissemination to the pulmonary circulation were discussed as well.
CONCLUSION
Metastasis must be considered in patients with intracranial meningiomas accompanied by venous sinus invasion and extension through the calvarium. Thorough paraclinical investigations are suggested in such cases.
简介
脑膜瘤是最常见的颅内肿瘤，通常表现为惰性行为。这些肿瘤很少出现硬膜外扩散和远处转移，而来自低级别脑膜瘤的肺转移则是罕见事件。
病例介绍
本病例报告旨在介绍一名 37 岁白人孕妇的临床、影像和病理特征，该孕妇在因原发性颅内脑膜瘤手术前的术前检查中意外发现双侧肺转移。还讨论了转移到肺循环的可能途径和传播的危险因素。
结论
对于伴有静脉窦侵犯和颅骨延伸的颅内脑膜瘤患者，必须考虑转移。在这种情况下，建议进行彻底的临床检查。
