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 1 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.
Colloid cysts are one of the infrequent benign primary intracranial tumours. Although they are histologically benign, they may lead acute hydrocephalus and sudden death by obstructing foramen Monro. Even though it was supposed to originate from paraphysis or from olfactory nerve because of the cilia that were detected on the cyst epithelium, today the epithelium is supposed to originate from endoderm/respiratory epithelium. Colloid cysts are surgically challenging because of their deep midline location. Early detection and entire excision of the colloid cyst carries an excellent prognosis as presented case.Keywords: Central nervous system cysts; third ventricleTurkiye Klinikleri J Med Sci 2007, 27:919-922
