Twenty-four years old male patient complained of severe headache for 2 months without any prominent physical finding or neurological deficits. A well circumscribed mass measuring I cm in diameter of the third ventricle and dilatation in the ventricular system was seen on cranial computerized tomography. On histological examination, the cystic lesion was composed of pseudostratified columnar ciliated epithelial lining. This epithelium was positive for cytokeratin and epithelial membrane antigen and negative for glial fibrillary acidic protein immunohistochemically. Under this epithelial lining a cyst wall with a thin fibrous capsule was detected. Homogenous, amorphous, eosinophilic material was found within this cyst.
