Background: Intracranial dural-based lesions can be due to benign or malignant processes. Imaging characteristics cannot always discern between different pathologic conditions. A thorough clinical evaluation may reveal likely diagnostic possibilities. However, in certain cases, the etiology of the underlying lesion may require biopsy or resection to appropriately treat the patient. Review Summary: We report the case of a large dural-based adenocarcinoma of the prostate clinically and radiographically mimicking a meningioma. We review the history and physical evaluation of the patient and subsequent treatment and response. We discuss the implications of dural-based intracranial lesions in patients with prostate cancer and review the literature of dural metastases, including the pathogenesis, tumor types, and clinical presentations. Conclusion: The differential diagnosis of dural-based lesions in the brain varies from incidental and benign to symptomatic and malignant. Careful vigilance in patients with a history of cancer and presenting with new symptoms or imaging evidence of dural-based lesions is critically important to provide timely intervention.
