Background: Extracranial metastasis from intracranial meningioma is a very rare condition. A
current literature review reveals that only few cases are documented with extensive
pulmonary involvement >10 years after initial intracranial meningioma resection. Diagnosis
of pulmonary meningioma is often confirmed by computed tomography chest-guided core
biopsies. The prognosis of extensive metastatic pulmonary meningioma, however, is
unknown and there is no gold standard treatment option. Case Description: We present a case of multiple pulmonary meningioma metastases developing 13 years
after initial resection of left occipital parafalcine World Health Organization Grade
I intracranial meningioma. Conclusion: There are no established guidelines for the optimal management or surveillance of
extensive pulmonary metastatic meningioma. In patients with high-grade meningioma
and multiple cannonball pulmonary lesions, metastatic meningioma should be considered
as part of the differential diagnosis. Metastatic meningioma may occur even a decade
after initial tumour resection.
