A case of unruptured aneurysm of the internal carotid artery presenting as olfactory hallucinations.

CONCLUSION: According to our knowledge, previous reports are limited to cases of large middle cerebral artery aneurysms compressing the lateral orbitofrontal cortex, and this is apparently the first report of a case where olfactory hallucinations occurred from direct stimulation of the entorhinal cortex by an internal carotid and posterior communicating artery bifurcation aneurysm. We examined the pathophysiology underlying the development of olfactory hallucinations. We found craniotomy clipping and focal resection to be useful from the standpoint of seizure control. Whether seizure control can also be obtained with intracranial aneurysm coiling should be investigated in the future. PMID: 28904824 [PubMed]

Publication date: Available online 12 December 2019Source: Journal of Clinical NeuroscienceAuthor(s): Ayataka Fujimoto, Kazuki Sakakura, Naoki Ichikawa, Tohru OkanishiAbstractEpilepsy surgery uses both depth electrodes (DEs) and subdural electrodes (SE). DEs have mainly been developed and used in Europe. As we are able to use the DEs safely due to the current advanced level of technology, use of DEs has been increasing rapidly over the last decade. Unlike placement of SEs, which simply requires craniotomy, DE placement generally requires stereotactic techniques such as frame-based stereotactic or robotic arm-based methods....

This article provides step-by-step descriptions of our surgical technique for non-lesional FLE. Sixteen patients undergoing eFL were included in this study. The goals were to maximize gray matter removal, including the orbital gyrus and subcallosal area, and to spare the primary motor and premotor cortexes and anterior perforated substance. The eFL consists of three steps: (1) positioning, craniotomy, and exposure; (2) lateral frontal lobe resection; and (3), resection of the rectus gyrus and orbital gyrus. Resection ahead of bregma allows preservation of motor and premotor area function. To remove the orbital gyrus preser...

This article presents a super obese patient (BMI 57 kg/m2) with drug-refractory epilepsy and obstructive sleep apnea who underwent left anterior temporal lobectomy through awake craniotomy to preserve language and memory, using warmed humidified high flow nasal cannula (HFNC) oxygen therapy. Awake craniotomy was facilitated by the use of HFNC, which proved essential to prevent airway collapse by creating continuous positive airway pressure through high flow and facilitated intraoperative neurologic language and memory testing while maintaining adequate oxygenation.

CONCLUSIONS: The circular grid is a safe, feasible tool that grants direct access to the cortical surgical surface for tissue resection while simultaneously monitoring electrical activity. Application of the circular grid to different brain pathologies may improve intraoperative epileptogenic detection accuracy and functional outcomes, while decreasing postoperative complications.

This study aimed to compare the curative effects of these two procedures in such patients. A retrospective study of patients older than years with spontaneous intracerebral hemorrhage was conducted between January 2012 and December 2015. Of the 86 patients, 47 received minimally invasive puncture and drainage and 39 underwent craniotomy. One year after surgery no statistically significant difference was observed between the two groups with respect to: evacuation rate of the hematoma five days after the operation, volume of residual hematoma, occurrence of rebleeding, development of infectious meningitis, length of hospital...

The benefits and common complications of cranioplasty are often mentioned, but fatal complications are rarely documented. Here, the authors report a patient of intracranial hemorrhage and death after cranioplasty and discussed the possible mechanism. A 42-year-old man was admitted with the diagnosis of massive cerebral infarction in left fronto-temporo- parietal lobe, emergency surgery for decompressive large craniotomy and Encephalo-Myo-Synangiosis were performed. One year after surgery, cranioplasty was performed using a titanium mesh plate. Intraoperative cerebrospinal fluid leakage was occurred and dura mater was repai...

Abstract OBJECTIVE: To report intraoperative periodic focal epileptiform discharges (PFEDs) during awake craniotomy using high-density electrocorticography (HD-ECoG). METHODS: We retrospectively analyzed 81 patients undergoing awake craniotomy between 9/29/2016 and 7/5/2018. Intraoperative HD-ECoG was performed with direct electrocortical stimulation (DECS) for functional brain mapping. Real-time interpretation was performed and compared to scalp EEG when performed. Perioperative seizures, surgical complications, and characteristics of PFEDs were assessed. RESULTS: 69/81 patients (mean age 48.5 years) ...

Authors: Lee EJ, Kalia SK, Hong SH Abstract Epilepsy surgery that eliminates the epileptogenic focus or disconnects the epileptic network has the potential to significantly improve seizure control in patients with medically intractable epilepsy. Magnetic resonance-guided laser interstitial thermal therapy (MRgLITT) has been an established option for epilepsy surgery since the US Food and Drug Administration cleared the use of MRgLITT in neurosurgery in 2007. MRgLITT is an ablative stereotactic procedure utilizing heat that is converted from laser energy, and the temperature of the tissue is monitored in real-time b...

Authors: Tomlinson SB, Buch VP, Armstrong D, Kennedy BC Abstract Stereoelectroencephalography (SEEG) is an invasive technique used during the surgical management of medically refractory epilepsy. The utility of SEEG rests in its ability to survey the three-dimensional organization of the epileptogenic zone as well as nearby eloquent cortices. Once concentrated to specialized centers in Europe and Canada, the SEEG methodology has gained worldwide popularity due to its favorable morbidity profile, superior coverage of deep structures, and ability to perform multilobar explorations without the need for craniotomy. Thi...
