Prostatic meningeal carcinomatosis with low serum level of prostate-specific antigen.

摘要

Less than 1% of patients with metastatic prostate cancer present with abnormally low serum levels of prostate-specific antigen (PSA). Furthermore, cases of prostatic metastases to the meninges with a low serum level of PSA are extremely rare. The present report describes a patient with prostatic meningeal carcinomatosis and low serum PSA levels.
