Choroid plexus metastasis from carcinoma of the bladder: case report and review of the literature

We present here a case report of a 40-year old male with adenocarcinoma of the bladder and solitary metastasis to the choroid plexus of the right late ral ventricle. This is the first such report of such a metastasis in associ ation with bladder carcinoma. Systemic metastases frequently occur in patie nts with carcinoma of the bladder but involvement of central nervous system is relatively uncommon: less than 1% of patients with carcinoma of the bla dder present an intracerebral metastasis. In the majority of cases there ar e either multiple CNS metastases or other distant metastases. A few cases p resent with solitary metastases to the CNS without evidence of recurrent or disseminated disease.
