title: Metastatic prostate adenocarcinoma invading an atypical meningioma.
abstract: Although prostate adenocarcinoma is the most commonly diagnosed cancer in men, intracranial metastases are rare. We describe a 72-year-old patient with known metastatic prostate cancer, presenting with a dural-based parafalcine lesion on radiological imaging, following a seizure. Total macroscopic excision of the lesion was achieved at surgery, with histopathology confirming prostate adenocarcinoma embedded in an atypical (World Health Organization Grade II) meningioma, fulfilling all the criteria for true tumour-to-tumour metastasis. To our knowledge, this is the first report of prostate cancer metastasising to an atypical meningioma.
