Eight patients with colloid cysts of the third ventricle were examined with CT and MR. In six, surgical resection was performed and the material was subjected to histologic evaluation; the concentrations of trace elements were determined by particle-induced X-ray emission. Stereotaxic aspiration was performed in two. The investigation showed that colloid cysts are often iso- or hypodense relati...

OBJECTIVE Colloid cysts (IIIVT CC) are benign neuroepithelial cysts located in the anterior third ventricle. The authors propose the use of Nd:YAG laser stereotactic neuroendoscopic for guided resection of the third ventricle colloid cysts. METHOD Eleven patients presented third ventricle colloid cysts and were treated by Nd:YAG laser guided with stereotactic endoscopy (n=7) , stereotactic en...

Colloid cysts of the third ventricle are rare, benign lesions that originate in the primitive neuroepithelium, which forms the roof plate of the tela choroidea [1-4] . Clinical presentation varies, symptoms being related to acute or chronic hydrocephalus. Intermittent headaches, gait disturbances, ataxia, fainting spells, mental disorders, and personality changes are encountered, alone or in co...

BACKGROUND Third ventricular colloid cysts account for 0.5% - 1.5% of all intracranial tumors. A thorough search of the world literature since 1858 revealed 1167 cases, for which a more than one-third (36%) management mortality was estimated. One third of the reported cases had modern diagnostics and surgery with minimal morbidity and nearly no mortality. The primary goal of this study was to a...

BACKGROUND AND PURPOSE Colloid cysts of the third ventricle are rare benign brain tumors. The purpose of this study was to correlate their patterns on MR images with the probability of success of percutaneous treatment. METHODS Nineteen patients underwent endoscopic treatment for colloid cysts of the third ventricle. The cases were divided into two groups based on difficulty of the aspiration...

AIM To compare the clinical results of different transcortical approaches for the removal of third ventricular colloid cysts (CC). MATERIAL AND METHODS Records of 41 colloid cyst patients who underwent transcortical conventional microsurgical, microsurgical with the aid of stereotactically guided cylindrical retractor (minitubular), and endoscopic removal between 1999 and 2015 were retrospect...

J Neurol Stroke 2017, 6(6): 00219 mm versus 8 mm), 3) ventricular dilation (83% versus 31%),and 4) increased signal on T2-weighted magnetic resonance images (44% versus 8%) [1]. More than half of cases were discovered incidentally. In five patients with incidental cysts (8.8%) an enlargement of the cyst was documented and a surgical procedure was done. Nearly half of symptomatic patients presen...
