Abstract

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.
