title: Dural metastases from prostate carcinoma: a systematic review of the literature apropos of six patients.
abstract: Intracranial metastases are a rare manifestation of prostate carcinoma and the dura mater is the most affected site. We report a series of six patients with dural prostate metastases (DPM) and perform a systematic review of the current literature in order to depict imaging trademarks of this condition. This review points to a magnetic resonance imaging (MRI) pattern of meningeal involvement characterized by a diffuse smooth thickening, nodular appearance or dural-based masses. We also demonstrate an osteoblastic pattern of lesions, particularly in sphenoid wing, by computed tomography (CT) scans. We suggest that these imaging findings may support an elevated index of suspicion of DPM in elderly men, including those patients without urologic symptoms.
