Choroid plexus carcinoma: A case report

Choroid plexus tumor (CPT) is a rare neoplasm, arising from the neuroepithelial lining.1 After its first description in 1832, more than 500 CPT patients have been described in literature.2 Three quarters of the patients are children, with tumors most often found in the lateral ventricles. In adults, the fourth ventricle and its recesses are the most common sites of origin.1 The histopathology of CPT ranges from a well demarcated benign papilloma (WHO grade I) to highly anaplastic, infiltrative carcinoma (WHO grade III, choroid plexus carcinoma [CPC]). Surgical resection alone is curative for benign tumors, but the optimal adjuvant therapy for the malignant ones has not yet been defined and the prognosis is poor.1,3 Our experience in successfully treating such a patient is therefore of interest.
