Prostate cancer dural metastasis resembling a meningioma.

CT images of a 56-year-old man with headache showed a meningioma-like mass in the occipital region. The tumor was well-defined and non-uniform with bone thickening and no internal calcification. Eventually, he was diagnosed on the basis of histopathology and immunostaining findings as having a dural metastasis from a prostate cancer.
