title: Stereotactic techniques for colloid cysts: roles of aspiration, endoscopy, and microsurgery.
abstract: Stereotactic surgical techniques were used to manage 25 consecutive patients with colloid cysts of the third ventricle. All patients had stereotactic aspiration as the initial procedure; it was successful in 13 (52%). In patients in whom aspiration failed, endoscopic visualization of the cyst and attempted removal, or microsurgical cyst resection via a transcortical approach was performed. Three elderly patients did not have a second procedure and were shunted. The computed tomographic appearance of a hypodense or isodense cyst indicates low-viscosity contents and predicts successful stereotactic aspiration. Stereotactic microsurgery is used in hyperdense cysts, or in those which cannot be aspirated.
