Intracranial dural metastatic prostate cancer can mimic meningioma: a report of two cases

Abstract

Cerebral metastases from any malignancy, including prostate carcinoma, may present as a meningeal mass, and differentiating the lesion from a meningioma can be challenging. We report the clinical and neuroimaging features of two patients with dural metastases from prostate carcinoma and discuss differentiation of metastatic lesions from meningioma. In both patients, it appeared that the prostate carcinoma had been successfully treated, and neither patient was found to have any other metastases at the time of diagnosis of the dural lesions.
