Popis: Representative patients were treated with total surgical mass resection, and each tumor was histopathologically confirmed to have a secretory meningioma, intradural metastasis of gynecologic origin, and dural metastasis of lung origin. The imaging findings of these patients were inconclusive in differentiating meningioma from metastasis; hence, advanced magnetic resonance imaging (MRI) techniques were considered. Based on these reports, we studied how to differentiate typical meningiomas from atypical and malignant meningiomas and other dura-based malignant tumors using conventional computed tomography and MRI.
