Modern cryoablation of the prostate is a procedure that has evolved since the early 1990s into a safer and more successful treatment of adenocarcinoma of the prostate. The improvement of this technique has taken place secondary to advancement in engineering, procedure refinement, temperature monitoring, and a better understanding of physiologic events during the freezing process. Long-term results are available that demonstrate durable efficacy equivalent to other therapies in low-risk groups. In moderate to high risk groups, results point toward equal to superior results than other standard therapies. New ideas on potency preservation using vacuum erection devices have improved men's return to function over the course of the postoperative year. Early morbidity issues, such as fistula formation and incontinence, have become much less problematic, with results between 0% and 1% in some series. Cryoablation of the prostate now offers significantly improved outcomes with a parallel decrease in morbidity.

The diagnosis of a tumor-to-tumor metastasis in the central nervous system most commonly involves metastasis to a meningioma. These combined lesions are often radiographically unsuspected and mimic a meningioma. Most commonly, the source of metastatic disease are carcinomas from the lung and breast. To our knowledge, fewer than a half dozen cases of metastatic prostatic adenocarcinoma to a meningioma have been documented in the literature. This report documents a 67-year-old man who presented with worsening confusion and altered mental status, accompanied by symptoms of increased urinary frequency, incontinence, and difficulty urinating. Imaging revealed a mass at the base of the bladder and an intracranial lesion, surrounded by edema, which was initially suspicious for intracranial metastasis of prostate cancer. Due to worsening neurological symptoms, the patient underwent craniotomy to remove the intracranial mass. The mass was comprised of a meningothelial meningioma, World Health Organization Grade I, accompanied by atypical epithelioid cells which demonstrated immunoreactivity to prostate specific antigen, chromogranin and neuron specific enolase antibodies, consistent with a metastatic prostatic adenocarcinoma with neuroendocrine differentiation. The patient suffered severe neurological complications post-operatively, developed multiple metastases and expired 12months later. The report reviews current theories as to why meningiomas are the most common host tumor for tumor-to-tumor metastases in the brain and reviews the literature on previously reported cases involving metastatic prostatic adenocarcinoma.
