title: Choroid plexus carcinoma secreting carbohydrate antigen 19-9 in an adult. Case report.
abstract: A 53-year-old man presented with a choroid plexus carcinoma in the body of the right lateral ventricle manifesting as gait disturbance due to left mild hemiparesis and papilledema. Subtotal removal of the tumor was performed. Histological examination revealed well-differentiated papillary adenocarcinoma. Immunohistochemical examination showed intense reactivity for carbohydrate antigen 19-9 (CA19-9). The serum level of CA19-9 was significantly high, but decreased rapidly after radiation therapy. Systemic examinations found no malignancy in other organs. This second case of choroid plexus carcinoma producing CA19-9 indicates that CA19-9 may be a useful marker of choroid plexus carcinoma.
