Cortex points that did not elicit an effect on stimulation were deemed non-eloquent. The identification of eloquent areas during cortical stimulation was as follows: somatosensory cortex - paresthesia appeared, receptive language cortex (Wernicke area) - speech arrest and anomia, motor language cortex (Broca area) - speech arrest during number counting. Definitive neurological complications occurred in 2/18 (11.1%) patients, each with neuropathic pain and partial motor seizures and right-hand hypoesthesia, respectively. The patient with non-lesional epilepsy (number 17) experienced no crisis to date (3-month follow-up, previously several crises per week) and the patient with cavernoma had no seizures after 3 months of follow-up. The patients with cortical dysplasia had, among the epilepsy cases, the longest follow-up in the present series and all experienced a major decrease in seizure frequency and duration (see table 3 for the Engel classes). Transient neurological complications were encountered in 3/18 (16.7%) cases, each one with transient hemiparesis, ataxia and dysgraphia, and right-hand hypoesthesia. 5) in the present series was cortical dysplasia in 3 (16.7%), gliosis and mahadev 8d cavernoma in 1 (5.6%) each, respectively.
The river Indus serpentine, made its way through the fields, irrigating them and then disappeared over the horizon. The stampede occurred as millions of pilgrims jostled for space at the Kumbh Mela to bathe in the holy river Ganges. A sterile field was placed over the operative field and the head was held using a Mayfield MR/X-Ray Skull clamp with Excite 3.0T Adaptor (Integra Lifescience, New Jersey, USA). The file size is over 20 Mb. Identification sterile tags were not routinely placed over the brain area, only in selected cases as presented in the literature. Typically, stimulation was performed over the entire exposed cortical surface using biphasic square wave pulses (0.5 msec per pulse, 50 Hz, 2-second duration) starting at 2.5 mA. 108. T.

Two independent neurosurgeons measured all volumetric primary brain tumour volumes using the Intellispace Portal (Philips®, Amsterdam, Netherlands) module BTumour tracking software.The lesions without contrast enhancement or slightly enhanced after gadolinium infusion were contoured using the T2/FLAIR hypersignal MR sequences and highly contrast-taking tumours were segmented using the T1 hypersignal after gadolinium infusion sequences.
All patients benefitted from an intraoperative 1.5 Tesla MRI (General Electric®, Boston, MA) and the imaging sequences for neuronavigation were 3D T1 after gadolinium injection with 1-mm slice thickness. Microsurgical resection was guided by the surgeon’s intraoperative observation and assessment of tumour margins. For patients with intractable epilepsy or unknown or doubtful origin, SEEG was used before any microsurgical resection is performed, even in the case of an identified structural lesion on preoperative MRI.

Figure 4 The impact of intraoperative MRI on the microsurgical resection in terms of volumes (as cc, upper side; as percentages, lower side). 0.01, figure 4, lower part). Figure 3 Intraoperative MRI duration (minutes). Before performing the intraoperative MRI evaluation to assess the extent of resection, the dura mater and skin were approximated. A new intraoperative MRI was performed when the neuronavigation became insufficiently accurate and/or to assess the presence of a residual tumour.
An intraoperative MRI was performed as described below. For primary brain tumours, tumour removal was performed by dissecting circumferentially around the tumour border, as determined by the registered preoperative MR images displayed on the neuronavigation system. Table 2Short review of the literature for the use of awake surgery and intraoperative MRI for primary brain tumours. The mean preoperative tumour volume of the primary brain tumours was 34.7 cc (median 10.7, range 0.534−130.25; standard deviation 41.2 cc). At the last follow-up, 12 (12/13, 92.3%) patients had volumetric tumour stability or a decreased volume. 10% between the two observers, both segmentations were compared to achieve a consensus volume. 351. 59 Ibid., Volume 34, New Delhi, 1969, p.
