Endoscopic removal of third ventricular colloid cysts has grown in popularity. The biggest issues concern radicality, cure or at least long-term control of the disease, and endoscopic remnants. Technologic advances in instrumentation and introduction of novel tools have greatly improved endoscopic results. Deeper knowledge of surrounding anatomy and awareness that colloid cysts vary in their position (foraminal or retroforaminal) can further improve with the selection of a tailored approach for each patient.
