Colloid Cysts of the Third Ventricle

Abstract

In this paper 33 cases of colloid cyst of the 3rd ventricle are presented. The initial symptoms as well as the clinical syndromes are quite variable, but usually consist of a combination of signs of increased intracranial pressure and an organic dementia, progressive or paroxysmal. Computed tomography is an invaluable diagnostic tool and it seems that, since it has become widely used in the evaluation of patients with headaches or dementia, colloid cysts are being recognized with increasing frequency. Different modalities of treatment are discussed. The transcortical and transcallosal approaches are both effective techniques, but the latter is probably preferable in cases with mild ventricular dilatation.

Complete endoscopic removal of colloid cysts: issues of safety and efficacy

“…It appears that the endoscopic technique is at least comparable to the other techniques recently published [1,8,12,13] and superior to results achieved in the microsurgical series that were published in the late 1980s. [2,6] …”

Remote transplantation of a third ventricle colloid cyst: case report

“…[4][5][6]21 Although these lesions often pose interesting management challenges to the neurosurgeon, such as whether to treat 25,26 and which approach to use if treatment is necessary, the possibility of a lost cyst capsule "metastasizing" to a new location is not generally considered a potential complication. High-grade tumors such as glioblastoma, medulloblastoma, and some forms of ependymoma are well known for their ability to metastasize to remote locations.…”

Quantification of white matter fibre pathways disruption in frontal transcortical approach to the lateral ventricle or the interventricular foramen in diffusion tensor tractography

“…transcortical route, up to 20% of patients may develop hemiparesis, which is attributed to the violation of centrum semiovale [3,15,39]. Memory deficits occur after the damage of nucleus caudatus or thalamocortical fibres [20].…”
