A 64-year-old male presented with a unique choroid plexus metastasis from gastric cancer. Computed tomography and magnetic resonance imaging demonstrated a moderately enhanced mass in the lateral ventricle. The tumor was totally removed and histological examination revealed adenocarcinoma. Systemic investigation revealed gastric cancer. The differential diagnosis for intraventricular masses should include the possibility of metastasis from unidentified primary lesions.
