Choroid plexus metastasis: CT appearance.
Tumors of the choroid plexus are rare, and included among the list of such tumors is metastasis. We report a case of lung carcinoma metastasizing to the choroid plexus of the lateral ventricle. This mass was isodense on unenhanced CT and demonstrated moderate to marked enhancement after intravenous contrast medium administration. Follow-up studies over the course of 2 1/2 months showed hemorrhage into the mass and periventricular enhancement. Confirmation of the diagnosis was made by stereotactic biopsy. The differential diagnosis of choroid plexus masses is reviewed.
