A 65-year-old male presented with abrupt onset of right hemiparesis. He was previously diagnosed with advanced adenocarcinoma of the prostate. Magnetic resonance imaging showed an extra-axial expansile lesion, located in the left perirolandic region associated with a nontraumatic subdural hematoma. Histopathology and immunohistochemistry of the lesion revealed metastatic prostate adenocarcinoma (Figure 1 and 2). Dural metastasis from prostate adenocarcinoma is a rare condition, responsible for 1% of all cases1. Pathogenetic mechanisms include hematogenous spread and surgical seeding2. A dural metastasis usually presents as a solitary mass with avid contrast enhancement. Bone erosion and nontraumatic subdural hematoma may rarely be seen3.
