[The pulmonary metastasis of a benign meningioma]. / Metástasis pulmonar de meningioma benigno.

We report a 53-year-old man with a solitary pulmonary nodule and signs of disease progression in chest films taken in the last year with lung metastasis from benign meningioma diagnosed by transthoracic puncture and aspiration. The rarity of this condition is discussed along with the need to include it as a differential diagnosis in patients with recurring meningioma even when the primary lesion is benign, given that early surgical resection of the metastasis resolves this complication.
