Pulmonary Metastatic Meningioma with Coincident Lung Cancer: A Case Report

Abstract

Meningiomas with distant metastases rarely occur. We report a patient with coincident primary lung cancer and metastatic meningiomas. The presence of distinct imaging features and a differential response to chemotherapy enabled us to distinguish the primary lung cancer from the metastatic lesions. Previous studies suggest that several factors can enhance the propensity of meningioma for metastasis. Thus, if a patient presents with multiple lung nodules and a history of meningioma with certain predisposing factors, metastatic meningioma should be considered in the differential diagnosis.
