title: Metastasis of prostatic adenocarcinoma simulating a falx meningioma.
abstract: A 56-year-old man, with known metastatic carcinoma of the prostate, presented with a single Jacksonian seizure. Examination revealed a tumor of the falx cerebri which demonstrated many characteristics of a meningioma. Although exceedingly rare, the tumor proved to be a meningeal metastasis of the prostatic adenocarcinoma. The relevant literature is reviewed.
