Recurrent Intracranial Meningioma with Pulmonary Metastasis

Abstract

Meningiomas rarely metastasize outside the intracranial compartment. We report a case of recurrent intracranial meningioma with lung metastasis in a 61-year-old male. The patient, with a 1-week history of mild right chest pain, was found to have a large right lung mass by chest roentgenography 14 years after resection of an intracranial meningioma of the transitional type. A computed tomography (CT)-guided biopsy for the lung tumor was done. The pathology showed findings consistent with a transitional type meningioma. A recurrent intracranial tumor was disclosed by brain magnetic resonance imaging (MRI) at the same time. The patient underwent a gross total resection of the brain tumor, but the metastatic lung tumor was left untreated at his request. Local recurrence of transitional meningioma was confirmed by pathological examination. At 2 months after the operation, the patient remained clinically well.
