Computed tomographic evaluation of intracranial metastases from carcinoma of the prostate.

Intracranial metastases from carcinoma of the prostate are thought to be rare. The majority of the lesions reported have been dural in location. Subdural and intracerebral tumors are rarer. A review of previous autopsy series reveals an average frequency of 2.4%. Computed tomography offers an accurate and simple method of confirming the presence of intracranial metastases from carcinoma of the prostate. We report and discuss two patients displaying dural tumor deposits, one with possible parenchymal extension.
