Abstract
- A case of papillary ependymoma in the left frontal lobe was presented, because in Korea the cerebral ependymoma with noattachment to the ventricles was very rare. The patient was 40 years old female who had complained of severe headache and experienced occasional generalized tonic convulsions for 2 years prior to admission. We could treat the patient successfully by surgery. The tumor mass was attached to a part of the wall of a large cystic cavity which located within the brain substance of left frontal lobe. The tumor tissue was soft and papillary, and looked like a choroid plexus in the ventricles or a mural nodule in the wall of a large cyst which we may find occasionally in cerebellar hemangioblastomas. The cyst was filled with clear limpid yellow fluid of about 120cc. The cyst-wall was not lined with any membrane, and was devoid of tumor tissue. The microscopic findings of tumor showed many papillary growths with the stroma having telangiectasias and irregular mixture of fibrous connective tissue and neuroglial cells.
