Choroid plexus papillary carcinoma associated with hemorrhage. A case report.

Choroid plexus papillary carcinoma is a rare intracranial malignant epithelial tumor. We describe a case of choroid plexus tumor arising in the periventricular parenchyma. A 52-year-old man presented with headache for five months, aggravated by vomiting for three days. Brain computed tomography scan revealed an inhomogeneous density lesion in the right temporoparietal lobe with mild enhancement, and hemorrhage anterior to the lesion. Histological and immunohistochemical findings indicated a choroid plexus papillary carcinoma.
