Dural metastases from disseminated prostate cancer clinically mimicking a benign reactive condition of the dura: case report and review of the literature.

Dural spread from prostate cancer (PC) is exceedingly uncommon. We report on a 62-year-old man suffering from disseminated PC with osseous metastases who presented with a parietal skull metastasis along with a circumscribed nodular thickening of the adjacent dura. Magnetic resonance imaging findings suggested a benign reactive condition of the dura which, however, histologically turned out to be a dural metastasis. Therefore, the present case report stresses the notion that very rarely, disseminated PC might present with clinically unsuspected dural metastases radiologically mimicking a benign condition.
