"

04/01/2004 - "The discussion focuses on colloid cyst potential to mimic other intracranial lesions, rendering accurate diagnosis difficult and leading to possibly inappropriate management in similar cases."
10/01/1994 - "These cases illustrate that xanthogranulomas of the third ventricle may clinically and radiologically mimic pure colloid cysts, that a range of MR imaging signals can be seen, and that craniotomy rather than stereotactic aspiration is the indicated treatment."

07/01/1989 - "Intermediate filament markers (cytokeratin, vimentin, neurofilament, and glial fibrillary acidic protein) and epithelial markers (epithelial membrane antigen and monoclonal antibody lu-5) demonstrated that colloid cyst epithelium has a unique antigenic profile in contrast to that of choroid plexus or glial tissue.
