Metastatic changes secondary to prostate cancer usually occur in bones, less commonly in pelvic lymph nodes, liver, lungs, urinary balder and brain. Less common localization includes skin, testis and other structures. The current paper reports a rare case of metastatic infiltration of the dura mater in patient with prostate cancer (Gleason 8 (4+4)) with disseminated bone metastasis. Magnetic resonance imaging revealed an advance infiltration of dura mater of anterior and posterior cranial fossa without any neoplasmatic-related changes in brain. Along optic nerves it penetrated to the optic canal and right orbit.
