Two rare cases of intractable epilepsy caused by Dysembryoplastic Neuroepithelial Tumours (DNET) are reported and their different management discussed. The first case required vagal nerve stimulation and radiosurgery while the later was operated with the help of neuronavigation. Both had good outcome according to Engel classification after a one year follow up.

BACKGROUND 5-Aminolevulinic acid (5-ALA) fluorescence is a validated technique for resection of high grade gliomas (HGG); the aim of this study was to evaluate the surgical outcome and the intraoperative findings in a consecutive series of patients. METHODS Clinical and surgical data from patients affected by HGG who underwent surgery guided by 5-ALA fluorescence at our Department between Jun...

OBJECTIVE: Surgery of the insula represents a technical challenge, because of the proximity of the internal capsule to the lenticulostriate arteries and the lack of certainty concerning its functionality. Using intraoperative direct cerebral stimulation, combined with neuronavigation, the authors operated on 12 insular gliomas. On the basis of this experience, the physiopathological and surgica...

OBJECT The objective of this study was to compare the accuracy of 3 methods of ventricular catheter placement during CSF shunt operations: the freehand technique using surface anatomy, ultrasonic guidance, and stereotactic neuronavigation. METHODS This retrospective cohort study included all patients from a single institution who underwent a ventricular CSF shunting procedure in which a new v...

BACKGROUND AND PURPOSE We determined the radiation dose in patients' lenses during pituitary surgery with either conventional fluoroscopy or CT-guided neuronavigation. MATERIALS AND METHODS Thermoluminescent dosimeters (TLD-100H) were attached to the lenses of an anthropomorphic Alderson-Rando head phantom. Simulation of the conventional setup of continuous fluoroscopy (61 kV peak, 2.01 mAs) ...

Abstract BACKGROUND When preparing for the resection of an intracranial lesion, its borders and optimal approach are often determined using neuronavigation with a tracked pointer. This can sometimes prove challenging, especially deep-seated lesions. Augmented reality (AR) simplify improve this step by directly displaying lesion on patient's skin. METHODS A proprietary inside-out infrared tracki...

Background . There are many variations of the developmental pathology anterior communicating artery with such forms as aplasia, hypoplasia, duplication, triplication and etc. The presence median corpus callosum is a rare part circle Willis and, according to literature frequency 4,5-14,2 %. About 81 % cases, occurrence combined trifurcation. incidence distal cerebral aneurysms has been estimated...
