Abstract
BACKGROUND Trials of surgical evacuation of supratentorial intracerebral hemorrhages have generally shown no functional benefit. Whether early minimally invasive surgical removal would result in better outcomes than medical management is not known. METHODS In this multicenter, randomized trial involving patients with an acute intracerebral hemorrhage, we assessed surgical removal of the hematoma as compared with medical management. Patients who had a lobar or anterior basal ganglia hemorrhage with a hematoma volume of 30 to 80 ml were assigned, in a 1:1 ratio, within 24 hours after the time that they were last known to be well, to minimally invasive surgical removal of the hematoma plus guideline-based medical management (surgery group) or to guideline-based medical management alone (control group). The primary efficacy end point was the mean score on the utility-weighted modified Rankin scale (range, 0 to 1, with higher scores indicating better outcomes, according to patients' assessment) at 180 days, with a prespecified threshold for posterior probability of superiority of 0.975 or higher. The trial included rules for adaptation of enrollment criteria on the basis of hemorrhage location. A primary safety end point was death within 30 days after enrollment. RESULTS A total of 300 patients were enrolled, of whom 30.7% had anterior basal ganglia hemorrhages and 69.3% had lobar hemorrhages. After 175 patients had been enrolled, an adaptation rule was triggered, and only persons with lobar hemorrhages were enrolled. The mean score on the utility-weighted modified Rankin scale at 180 days was 0.458 in the surgery group and 0.374 in the control group (difference, 0.084; 95% Bayesian credible interval, 0.005 to 0.163; posterior probability of superiority of surgery, 0.981). The mean between-group difference was 0.127 (95% Bayesian credible interval, 0.035 to 0.219) among patients with lobar hemorrhages and -0.013 (95% Bayesian credible interval, -0.147 to 0.116) among those with anterior basal ganglia hemorrhages. The percentage of patients who had died by 30 days was 9.3% in the surgery group and 18.0% in the control group. Five patients (3.3%) in the surgery group had postoperative rebleeding and neurologic deterioration. CONCLUSIONS Among patients in whom surgery could be performed within 24 hours after an acute intracerebral hemorrhage, minimally invasive hematoma evacuation resulted in better functional outcomes at 180 days than those with guideline-based medical management. The effect of surgery appeared to be attributable to intervention for lobar hemorrhages. (Funded by Nico; ENRICH ClinicalTrials.gov number, NCT02880878.).

Abstract
OBJECTIVE The lateral retrocanthal transorbital endoscopic approach (LRCTEA) facilitates trajectory to the middle fossa, preserving the lateral canthal tendon and thus avoiding postoperative complications such as eyelid malposition. Here, the authors sought to define the surgical anatomy and technique of LRCTEA using a stepwise approach in cadaveric heads and offer an in-depth examination of existing quantitative data from cadaveric studies. METHODS The authors performed LRCTEA to the middle cranial fossa under neuronavigation in 7 cadaveric head specimens that underwent high-resolution (1-mm) CT scans preceding the dissections. RESULTS The LRCTEA provided access to middle fossa regions including the cavernous sinus, Meckel's cave, and medial temporal lobe. The trajectories and endpoints of the approach were confirmed using electromagnetic neuronavigation. A stepwise approach was delineated and recorded. CONCLUSIONS The authors' cadaveric study delineates the surgical anatomy and technique of the LRCTEA, providing a stepwise approach for its implementation. As these approaches continue to evolve, their development and refinement will play an important role in expanding the surgical options available to neurosurgeons, ultimately improving outcomes for patients with complex skull base pathologies. The LRCTEA presents a promising advancement in skull base surgery, particularly for accessing challenging middle fossa regions. However, surgeons must remain vigilant to potential complications, including transient diplopia, orbital hematoma, or damage to the optic apparatus.

Abstract
BACKGROUND Hürthle cell carcinoma (HCC) is an unusual and aggressive variant of the follicular type of differentiated thyroid cancer (DTC), accounting for less than 3% of DTCs but posing the highest risk of metastasis. Brain metastases are uncommonly reported in the literature but pose a poor prognosis. The low rate of brain metastases from HCC coupled with ambiguous treatment protocols for the extracranial disease complicate successful disease management and definitive treatment strategy. The authors present the case of a patient with HCC metastasis to the skull base, cortex, and spine with recent tibial metastasis. OBSERVATIONS Despite the presence of metastasis to the cortex, skull base, and spine, the patient responded very well to radiation therapy, sellar mass resection, and cervical spine decompression and fixation and has made a remarkable recovery. LESSONS The authors' multidisciplinary approach to the patient's care, including a diverse team of specialists from oncology, neurosurgery, orthopedic surgery, radiology, endocrinology, and collaboration with clinical trial researchers, was fundamental to her successful outcome, demonstrating the utility of intersecting specialties in successful outcomes in neuro-oncological patient care.

Abstract
BACKGROUND Traditional management of olfactory neuroblastoma (ONB) includes margin-negative resection with removal of cribriform plate, dura, and olfactory bulb, regardless of intracranial disease. This approach may be overtreating certain patients. Our investigation examines risk factors associated with occult intracranial disease to optimize therapeutic outcomes. METHODS This retrospective, multi-institutional cohort study examined clinical covariates associated with occult intracranial involvement. Patient demographics, staging, Hyam's grade, and pathologic involvement of dura, olfactory bulb/tract, and brain were collected. Diagnostic imaging was reviewed. Positive and negative predictive value (NPV) were estimated along with effect size estimates. Cox hazard regression examined associations with overall survival (OS) and disease-free survival (DFS). RESULTS A total of 224 subjects with new diagnoses of ONB (2005-2021) were identified. Skull base bone involvement on computed tomography (CT) had the highest NPV for pathologic dura (88.0%), olfactory bulb (88%), and brain involvement (97.3%). Hyam's grade category was significantly associated with dural involvement (φC = 0.26; 95% confidence interval [CI]: 0.16, 0.42). Subjects without radiologic skull base involvement (n = 66) had pathologic positivity of 12.1%. Within this subgroup, Hyam's grade was clinically significant for dural positivity (φ = 0.34; 95% CI: -0.12, 0.71) with 28.6% involvement in high grade tumors. Neither clinical nor pathologic positivity of intracranial structures were associated with significantly different OS or DFS. CONCLUSIONS Both CT and magnetic resonance imaging (MRI) had reasonably good NPV for involvement of dura and olfactory bulb. Higher Hyam's grade was associated with dural involvement. Patients with low-grade tumors not involving the skull base may be suitable for avoiding skull base resection; however, further investigation is warranted.

Abstract
Importance Current olfactory neuroblastoma (ONB) staging systems inadequately delineate locally advanced tumors, do not incorporate tumor grade, and poorly estimate survival and recurrence. Objective The primary aims of this study were to (1) examine the clinical covariates associated with survival and recurrence of ONB in a modern-era multicenter cohort and (2) incorporate Hyams tumor grade into existing staging systems to assess its ability to estimate survival and recurrence. Design, Setting, and Participants This retrospective, multicenter, case-control study included patients with ONB who underwent treatment between January 1, 2005, and December 31, 2021, at 9 North American academic medical centers. Intervention Standard-of-care ONB treatment. Main Outcome and Measures The main outcomes were overall survival (OS), disease-free survival (DFS), and disease-specific survival (DSS) as C statistics for model prediction. Results A total of 256 patients with ONB (mean [SD] age, 52.0 [15.6] years; 115 female [44.9%]; 141 male [55.1%]) were included. The 5-year rate for OS was 83.5% (95% CI, 78.3%-89.1%); for DFS, 70.8% (95% CI, 64.3%-78.0%); and for DSS, 94.1% (95% CI, 90.5%-97.8%). On multivariable analysis, age, American Joint Committee on Cancer (AJCC) stage, involvement of bilateral maxillary sinuses, and positive margins were associated with OS. Only AJCC stage was associated with DFS. Only N stage was associated with DSS. When assessing the ability of staging systems to estimate OS, the best-performing model was the novel modification of the Dulguerov system (C statistic, 0.66; 95% CI, 0.59-0.76), and the Kadish system performed most poorly (C statistic, 0.57; 95% CI, 0.50-0.63). Regarding estimation of DFS, the modified Kadish system performed most poorly (C statistic, 0.55; 95% CI, 0.51-0.66), while the novel modification of the AJCC system performed the best (C statistic, 0.70; 95% CI, 0.66-0.80). Regarding estimation of DSS, the modified Kadish system was the best-performing model (C statistic, 0.79; 95% CI, 0.70-0.94), and the unmodified Kadish performed the worst (C statistic, 0.56; 95% CI, 0.51-0.68). The ability for novel ONB staging systems to estimate disease progression across stages was also assessed. In the novel Kadish staging system, patients with stage VI disease were approximately 7 times as likely to experience disease progression as patients with stage I disease (hazard ratio [HR], 6.84; 95% CI, 1.60-29.20). Results were similar for the novel modified Kadish system (HR, 8.99; 95% CI, 1.62-49.85) and the novel Dulguerov system (HR, 6.86; 95% CI, 2.74-17.18). Conclusions and Relevance The study findings indicate that 5-year OS for ONB is favorable and that incorporation of Hyams grade into traditional ONB staging systems is associated with improved estimation of disease progression.

Abstract
OBJECTIVE Skull base chordoma is a rare and locally destructive malignancy which presents unique therapeutic challenges. While achieving gross total resection (GTR) confers the greatest survival advantage, the role of adjuvant radiotherapy (RT) for patients who receive GTR remains unclear in the absence of prospective trials. Here, we aim to assess the effect of RT on survival outcomes in skull base chordoma patients who receive GTR by utilizing the Surveillance, Epidemiology, and End Results (SEER) database. METHODS Patients with diagnostic, primary site, and resection codes specific for chordoma, skull base, and GTR, respectively, were queried in the SEER database (2000-2018). Kaplan-Meier curves (log-rank test) were constructed and Cox proportional hazards models were used to assess survival outcomes. RESULTS A total of 115 skull base chordomas undergoing GTR were identified, of which 37 (32%) received no RT and 78 (68%) received RT. Median follow-up was 55.00 months (range: 0.00-227.00). Overall survival (OS) of patients with GTR was 85% and 70% at 5 and 10 years, respectively. Multivariate Cox proportional hazard analysis among chordoma patients undergoing GTR found age ≥65 (P < 0.01) was associated with poorer OS outcomes. RT appeared to trend toward offering benefit in terms of OS in patients after GTR, however this did not achieve statistical significance in the adjusted model (HR = 0.51, CI = 0.23-1.16, P = 0.09). When comparing, disease-specific survival was also not improved in patients undergoing RT (HR = 0.58, CI = 0.23-1.46, P = 0.25). CONCLUSIONS It remains unclear whether RT after GTR of chordoma improved survival outcomes among SEER database patients.

Abstract
OBJECTIVE Prealbumin levels correlate with overall nutritional status, and low values are associated with poor wound healing. We investigated whether low preoperative prealbumin levels predict risk of endoscopic endonasal skull base surgery (EESBS) reconstruction failure, as demonstrated by postoperative cerebrospinal fluid (CSF) leak and/or infection. METHODS Between October 2018 and February 2020, 98 patients with documented preoperative prealbumin levels were prospectively followed. The incidence of CSF leak and infection in patients with low prealbumin levels (≤20 mg/dL) was compared with those with normal prealbumin levels (>20 mg/dL). Numerous factors previously shown to influence CSF leak rates were assessed. Both univariate and multivariable analyses were performed to identify independent predictive factors. RESULTS Within this prospectively gathered patient cohort composed of >95% "high-risk" expanded EESBS, 14 of 98 patients (14.3%) experienced a postoperative CSF leak. Factors univariately associated with postoperative complications at the 0.2 level of significance were used in a multivariable model. Low prealbumin levels (≤20 mg/dL) proved to be a strong independent predictive factor associated with a 5-fold increased risk of postoperative CSF leak (odds ratio 5.01, P = 0.01), and postoperative surgical-site infection (P = 0.0009). These associations remained after controlling for multiple other factors, including body mass index, surgical pathology, previous EESBS, risk assessment index, and high- versus low-flow intraoperative CSF leaks. CONCLUSIONS Preoperative prealbumin levels are an independent predictor of EESBS associated CSF leak and infection. Future studies are needed to investigate the utility of screening and correcting prealbumin levels to limit postoperative complications.

Abstract
Abstract
Cushing's syndrome, a disorder of cortisol excess, is associated with significant morbidity and mortality. Obesity, hypertension and glucose intolerance are common clinical findings in patients with Cushing's, but with the increasing incidence of obesity worldwide-- nearly 40% of the world's adult population is currently overweight– and the increasing incidence of obesity-associated comorbidities of hypertension and diabetes mellitus, deciding whom to screen for Cushing's can be very challenging and frequently delays timely diagnosis. We performed a retrospective study in patients with Cushing's disease (CD) and those with a clinically non-functioning ACTH-staining adenoma (NF-ACTH+) who underwent endoscopic endonasal resection at a large academic health center from 1/2015-7/2021 to investigate whether there are differences in weight-gain trajectories that can help differentiate patients with Cushing's from those without, even in a population that is predominantly overweight-obese. We hypothesized that patients with Cushing's would have significantly greater increases in weight in the six months preceding surgery compared to NF-ACTH+ patients with similar pre-operative evaluation and similar pre-operative BMI. Patients with CD (n=50) were younger (mean+SD: 45.9+15.4 years) compared to patients with NF-ACTH+ (n=34) (54.2+15.1 years, p=0. 02) and a higher percentage were female (CD: 86% versus NF-ACTH+: 50%, p=0. 0003). CD and NF-ACTH+ patients were of similar BMI (CD: 34.5+9.2 kg/m 2 and NF-ACTH+: 33.8+6.7 kg/m 2, p=0.93), even after controlling for age and sex (p=0.47), and >90% of both CD and NF-ACTH+ had a BMI of >25 kg/m 2 . Median weight change in the six months prior to surgery was 2.5 [0.3, 5.4] kg in CD and -0.5 [-2.7, 1.6] kg in NF-ACTH+ (p<0. 02); 77% of CD versus 43% of NF-ACTH+ gained weight during the six-month period (p=0. 02). Using a minimally clinically significant weight gain of 2kg, 56.4% of CD versus 21.4% of NF-ACTH+ gained >2kg in the six months preceding surgery (p=0. 02); using a 3kg cut off, 46% of CD versus only 14.3% of NF-ACTH+ gained >3kg in the six months preceding surgery (p=0. 03). After controlling for use of insulin in the setting of diabetes mellitus, the results remained significant with more CD patients than NF-ACTH+ gaining >2kg or >3kg in the six months prior to surgery (p<0. 04 for both analyses). These data demonstrate that patients with Cushing's are significantly more likely to gain at least 2kg (4.4 lbs) over a six-month period compared to a similarly overweight/obese population without clinical Cushing's, independent of the use of insulin in the setting of diabetes mellitus. A weight increase of at least 2kg can potentially allow weight to continue to be used as a helpful sign of Cushing's despite the increasing incidence of obesity. Collectively, these data suggest value in using weight trajectories, rather than absolute BMI, as a clinical variable when assessing the pretest probability of Cushing's.

Abstract
Intraoperative distinction of pituitary adenoma from normal gland is critical in maximizing tumor resection without compromising pituitary function. Contact endoscopy provides a noninvasive technique that allows for real-time in vivo visualization of differences in tissue vascularity. Two illustrative cases of endoscopic endonasal approaches (EEAs) for resection of pituitary adenoma illustrate the use of contact endoscopy in identifying tumor from gland and differentiating a thin section of normal gland draped over the underlying tumor, thereby allowing for safe extracapsular tumor resection. Contact endoscopy may be used as an adjunct for intraoperative, in vivo differentiation of pituitary gland and adenoma.

Abstract
BACKGROUND Chiari I malformations secondary to other causes represent a small subset of presenting symptomatic cases. Typically, the primary cause of the malformation is addressed first and results in resolution of the malformation and symptoms. However, in some cases, a patient may present with both a primary Chiari I malformation and another unrelated neurosurgical lesions. OBJECTIVE To present a unique case in which resection of a ventral tumor allowed for spontaneous resolution of a simultaneously noted dorsal Chiari I malformation. METHODS Pertinent data, including presenting symptoms, hospital course, surgical notes, preoperative images, and postoperative images, were collected using the electronic medical record. RESULTS We present a case of a 46-yr-old man with a Chiari I malformation in conjunction with a ventral cranio-cervical junction chordoma. Endoscopic endonasal resection of the chordoma and ventral foramen magnum decompression resulted in radiographic resolution of the Chiari malformation and resolution of his symptoms. Our report represents a rare case of ventral foramen magnum decompression as a treatment for Chiari I malformation. CONCLUSION It is felt that the chordoma mass effect was not the source of the Chiari I malformation. Thus, both ventral and dorsal decompressions of the posterior fossa may be considered for Chiari I decompression in select circumstances.

Abstract
Abstract
BACKGROUND
The optimal surgical treatment of suprasellar meningiomas remains controversial. While successful surgery has historically been measured by extent of tumor resection (EOR), surgeons must also balance tumor- and patient-specific characteristics with quality of life (QoL) outcomes when considering either an open craniotomy or endoscopic endonasal approach (EEA).
METHODS
We conducted 28 in-depth individual interviews with patients diagnosed with suprasellar meningioma and treated via EEA (n=14) or craniotomy (n=14). We used a structured interview script and the transcribed interviews were independently coded by two researchers. Consensus was used to identify themes and domains of interest.
RESULTS
The overall sample (80% between 40-69 years old, 70% female, and 82% white) was largely similar between craniotomy and EEA cohorts. Tumor volumes were not different between both cohorts (p=0.2), with a combined average of 4.4 cm3 (standard error ± 0.7). Suprasellar meningiomas caused a wide range of symptoms with 21 concepts elicited. The most frequently endorsed concepts were “Vision” (n=22), “Headaches” (n=11), “Fatigue” (n=11), “Cognitive Symptoms” (n=10), “Pituitary Dysfunction – including Trouble Sleeping and Frequent Urination” (n=9), “Sinus Problems” (n=7), and “Personality Changes” (5). Both surgical approaches demonstrated improvements in vision (69.2% EEA, 66.7% craniotomy) and headaches (100% EEA, 80% craniotomy). Compared to EEA, craniotomy yielded a longer list of complications (3 vs.14) and surgery-specific symptoms (9 vs.16). More craniotomy patients reported having negative emotions (5 vs.1), new depression and anxiety (6 vs.1), financial difficulties (3 vs.1), and reduced desire/ability to pursue fun activities (12 vs.7) after surgery relative to EEA counterparts.
CONCLUSION
Suprasellar meningiomas can be debilitating with significantly impact on patients’ health and QoL. Our findings demonstrate differential effects upon patients’ post-operative QoL associated with type of surgery. Our findings support the need for measuring patient-centered, disease-specific QoL outcomes in patients undergoing craniotomy versus EEA for suprasellar meningioma resection.

Abstract
BACKGROUND Many studies have explored molecular markers of carotid plaque development and vulnerability to rupture, usually having examined whole carotid plaques. However, there are regional differences in plaque morphology and known shear-related mechanisms in areas surrounding the lipid core. OBJECTIVE To determine whether there are regional differences in protein expression along the long axis of the carotid plaque and how that might produce gaps in our understanding of the carotid plaque molecular signature. METHODS Levels of 7 inflammatory cytokines (IL-1β, IL-6, IL-8, IL-10, IL-12 p70, IFN-γ, and TNF-α) and caspase-3 were analyzed in prebifurcation, bifurcation, and postbifurcation segments of internal carotid plaques surgically removed from symptomatic and asymptomatic patients. Expression profiles of miRNAs and mRNAs were determined with microarrays for the rupture-prone postbifurcation segment for comparison with published whole plaque results. RESULTS Expression levels of all proteins examined, except IL-10, were lowest in the prebifurcation segment and significantly higher in the postbifurcation segment. Patient group differences in protein expression were observed for the prebifurcation segment; however, no significant differences were observed in the postbifurcation segment between symptomatic and asymptomatic patients. Expression profiles from postbifurcation carotid plaques identified 4 novel high priority miRNAs differentially expressed between patient groups (miR-214, miR-484, miR-942, and miR-1287) and 3 high-confidence miRNA:mRNA targets, including miR-214:APOD, miR-484:DACH1, and miR-942:GPR56. CONCLUSION The results demonstrate regional differences in protein expression for the first time and show that focus on the rupture-prone postbifurcation region leads to prioritization for further study of novel miRNA gene regulation mechanisms.

Abstract
This is the case of a 76-year-old woman presenting with progressive right vision loss consisting of a right eye temporal field cut and severe visual acuity loss. An MRI was performed showing a suprasellar mass for which she had been referred to our center for an endoscopic endonasal approach. The tumor was found to be densely adherent to adjacent structures, and an ophthalmic artery and A1-A2 junction injury were sustained during resection. The management of intraoperative vascular injuries is described. The video can be found here: https://youtu.be/JJY6nYKTCSg.

Abstract
BACKGROUND Classic geniculate neuralgia (GN) is a rare condition characterized by lancinating pain centered in the ear and not involving the throat. To the best of our knowledge, no case of pediatric GN has been reported in the English literature. CASE PRESENTATION We present the first reported case of successfully treated GN in a child via an endoscopic approach. The patient was a 9-year-old boy who presented with a 1-year history of lancinating right ear pain. Neuroleptics resulted in a short-lived improvement in symptoms, but with significant side effects. Extensive evaluation by multiple specialties did not reveal a cause for his pain. Imaging disclosed a tortuous loop of the right posterior inferior cerebellar artery abutting cranial nerves IX and X but no other abnormalities. The patient underwent an endoscopic microvascular decompression of cranial nerves IX and X, and sectioning of the nervus intermedius through a right retromastoid craniotomy. Postoperatively, the patient reported complete resolution of his symptoms that persisted at 3 months of follow-up. At the 5-year follow-up, the patient maintained pain relief and was developing normally. CONCLUSION GN can affect the pediatric population. In carefully selected patients with consistent clinical and radiographic presentation, sectioning of the nervus intermedius and microvascular decompression of the lower cranial nerves can be an effective treatment.

Abstract
OBJECTIVEPituitary adenomas may extend into the parapeduncular space by invading through the roof of the cavernous sinus. Currently, a transcranial approach is the preferred choice, with or without the combination of an endonasal approach. In this paper the authors present a novel surgical approach that takes advantage of the natural corridor provided by the tumor to further open the oculomotor triangle and resect tumor extension into the parapeduncular space.METHODSSix injected specimens were used to demonstrate in detail the surgical anatomy related to the approach. Four cases in which the proposed approach was used were retrospectively reviewed.RESULTSFrom a technical perspective, the first step involves accessing the superior compartment of the cavernous sinus. The interclinoid ligament should be identified and the dura forming the oculomotor triangle exposed. The oculomotor dural opening may be then extended posteriorly toward the posterior petroclinoidal ligament and inferolaterally toward the anterior petroclinoidal ligament. The oculomotor nerve should then be identified; in this series it was displaced superomedially in all 4 cases. The posterior communicating artery should also be identified to avoid its injury. In all 4 cases, the tumor invading the parapeduncular space was completely removed. There were no vascular injuries and only 1 patient had a partial oculomotor nerve palsy that completely resolved in 2 weeks.CONCLUSIONSThe endoscopic endonasal transoculomotor approach is an original alternative for removal of tumor extension into the parapeduncular space in a single procedure. The surgical corridor is increased by opening the dura of the oculomotor triangle and by working below and lateral to the cisternal segment of the oculomotor nerve.

Abstract
BACKGROUND Ventriculoatrial shunts are common alternatives for patients who cannot tolerate ventriculoperitoneal shunts. The majority of ventriculoatrial shunt malfunctions are related to mechanical problems. We report an interesting case of ventriculoatrial shunt malfunction due to elevated central venous pressure from new-onset atrial fibrillation. METHODS After the patient was confirmed to have ventriculomegaly, he was taken to the operating room for exploration of his ventriculoatrial shunt; there were no obstructions. Subsequently, the patient was cardioverted to normal sinus rhythm for his new onset atrial fibrillation. RESULTS The clinical syndrome and ventriculomegaly both resolved after the patient's atrial fibrillation was corrected with chemical cardioversion. CONCLUSIONS The cause of this patient's VA shunt malfunction was likely associated with his new onset atrial fibrillation.

Abstract
OBJECTIVE Scheduled early postoperative computed tomography (EPOCT) after craniotomy for brain tumor resection is standard at many institutions. We analyzed utility of preplanned EPOCT after elective craniotomy for brain tumor resection. METHODS We retrospectively analyzed 755 brain tumor resections for which EPOCT was performed within 4 hours of surgery. Postoperative clinical neurologic examination results were classified into expected (baseline or predicted postoperative examination), changed (from baseline examination), and unreliable (sedated or baseline comatose patient). Scans were analyzed for unexpected and/or worrisome findings (e.g., hemorrhagic or ischemic stroke). In cases of unexpected findings, management changes were correlated to patient's neurologic examination. Demographic information, tumor histology, and tumor location were analyzed to determine risk factors for unexpected findings. RESULTS Rate of unexpected EPOCT findings was 4.1%. Patients with expected postoperative examinations were at significantly lower risk of abnormal findings (odds ratio [OR] = 0.074, P < 0.001). Patients with intraventricular tumors (OR = 5.7, P = 0.001) were at higher risk compared with patients with metastatic tumors (OR = 0.24, P = 0.06). No unexpected EPOCT findings led to management changes in patients with expected postoperative neurologic examinations. All unexpected EPOCT findings in patients with changed postoperative neurologic examinations led to management changes. Patients with nonreliable neurologic examinations were at significantly higher risk for unexpected findings on EPOCT (OR = 6.33, P < 0.001) and subsequent management changes. CONCLUSIONS Routine EPOCT is not indicated for patients undergoing brain tumor resection if postoperative neurologic examination is unchanged, as imaging is unlikely to result in management changes. EPOCT should be obtained in all patients with worrisome changes in examination or nonreliable examinations, as both groups have high rates of unexpected findings on imaging that lead to management changes.

Abstract
OBJECTIVE Meningiomas are the most common benign extramedullary lesions of the foramen magnum; however, their optimal management remains undefined. Given their location, foramen magnum meningiomas (FMMs) can cause significant morbidity, and complete microsurgical removal can be challenging. Anterior and anterolateral FMMs carry greater risks with surgery, but they comprise the majority of these lesions. As an alternative to resection, stereotactic radiosurgery (SRS) has been used to treat FMMs in small case series. To more clearly define the outcomes of SRS and to delineate a rational management paradigm for these lesions, the authors analyzed the safety and efficacy of SRS for FMM in an international multicenter trial. METHODS Seven medical centers participating in the International Gamma Knife Research Foundation (IGKRF) provided data for this retrospective cohort study. Patients who were treated with Gamma Knife radiosurgery and whose clinical and radiological follow-up was longer than 6 months were eligible for study inclusion. Data from pre- and post-SRS radiological and clinical evaluations were analyzed. Stereotactic radiosurgery treatment variables were recorded. RESULTS Fifty-seven patients (39 females and 18 males, with a median age of 64 years) met the study inclusion criteria. Thirty-two percent had undergone prior microsurgical resection. Patients most frequently presented with cranial neuropathy (39%), headache (35%), numbness (32%), and ataxia (30%). Median pre-SRS tumor volume was 2.9 cm3. Median SRS margin dose was 12.5 Gy (range 10-16 Gy). At the last follow-up after SRS, 49% of tumors were stable, 44% had regressed, and 7% had progressed. Progression-free survival rates at 5 and 10 years were each 92%. A greater margin dose was associated with a significantly increased likelihood of tumor regression, with 53% of tumors treated with > 12 Gy regressing. Fifty-two percent of symptomatic patients noted some clinical improvement. Adverse radiation effects were limited to hearing loss and numbness in 1 patient (2%). CONCLUSIONS Stereotactic radiosurgery for FMM frequently results in tumor control or tumor regression, as well as symptom improvement. Margin doses > 12 Gy were associated with increased rates of tumor regression. Stereotactic radiosurgery was generally safe and well tolerated. Given its risk-benefit profile, SRS may be particularly useful in the management of small- to moderate-volume anterior and anterolateral FMMs.

Abstract
Adult neurogenesis has been the center of attention for decades. Neuroscientists hope to understand the mechanism underlying this phenomenon that might provide a unique perception of brain repair in future. Neurogenesis is referred to the process in which neuronal stem cells and progenitors generate new neurons in non-pathologic setting. Although there are some similarities between two neurogenetic regions including hippocampus and olfactory bulb, however there are some important differences. Regardless of the unique functional roles of ongoing neurogenesis in olfactory bulb and hippocampus, the differences are in terms of consequence of neurogenesis, origin of newly born neurons, responding receptors to nicotine exposure, neuronal migration and GABAergic input between two regions. In this paper, we have briefly reviewed the differences of adult neurogenesis between olfactory bulb and hippocampus.

Abstract
Object
Microsurgical management of foramen magnum meningiomas (FMMs) can be associated with significant morbidity and mortality. Stereotactic radiosurgery may be an efficient and safe alternative treatment modality for such tumors. The object of this study was to increase the documented experience with Gamma Knife surgery (GKS) for FMMs and to delineate its role in an overall management paradigm.
Methods
The authors report on their experience with 24 patients harboring FMMs managed with GKS. Twelve patients had primary symptomatic tumors, 5 had asymptomatic but enlarging primary tumors, and 7 had recurrent or residual tumors after a prior surgery.
Results
Follow-up clinical and imaging data were available in 21 patients at a median follow-up of 47 months (range 3–128 months). Ten patients had measurable tumor regression, which was defined as an overall volume reduction > 25%. Eleven patients had no further tumor growth. Two patients died as a result of advanced comorbidities before follow-up imaging. One patient was living 8 years after GKS but had no clinical evaluation. Ten of 17 symptomatic patients with at least 6 months of follow-up had symptom improvement, and 7 remained clinically stable. Smaller tumors were more likely to regress. No patient suffered an adverse radiation effect after radiosurgery.
Conclusions
Gamma Knife surgery was a safe management strategy for small, minimally symptomatic, or growing FMMs as well as for residual tumors following conservative microsurgical removal.

Abstract
OBJECT Spinal aneurysmal bone cysts (ABCs) constitute a rare and clinically challenging disease, primarily affecting the pediatric population. Information regarding the management of spinal ABCs remains sparse. In this study the authors review their experience with spinal ABCs at Children's Hospital Boston. METHODS The medical records of all patients treated surgically for primary spinal ABCs between January 1998 and July 2010 were retrospectively reviewed. RESULTS Fourteen cases were identified (6 males and 8 females, ages 5-19 years old). The ABCs were located throughout the spine, with an equal number in the thoracic and lumbar spine, and rarely in the cervical spine. The majority of patients presented with back pain, but neurological deficits and spinal deformity were common. A variety of radiographic techniques were used to establish the diagnosis, including needle biopsy. Preoperative selective arterial embolization was performed in 7 cases (50%), and the majority of cases required spinal instrumentation along with resection. Mean follow-up was 55.9 months (range 15-154 months) after initial intervention. Two ABCs recurred (14%), at 9 months and 8 years after incomplete initial resection, and the patients underwent reoperation. Complete resection was ultimately achieved in all cases. All patients were asymptomatic and neurologically intact at their last follow-up evaluation, and showed no evidence of deformity or recurrence on imaging. CONCLUSIONS Computed tomography and MR imaging are adequate for an initial evaluation of spinal ABCs, although solid variants can present a diagnostic challenge. Given the high rates of recurrence with residual disease, complete obliteration of the lesion should be the goal of treatment. Preoperative embolization is often performed, although in the authors' opinion the degree of bleeding tends not to support its routine use. Long-term follow-up is warranted as recurrences can occur years after initial intervention. However, gross-total excision in conjunction with spinal stabilization, as needed, usually provides cure of the ABC and excellent long-term spinal alignment.

Abstract
Abstract
Background:
Despite abundant published support of patch angioplasty during carotid endarterectomy (CEA), primary closure is still widely used. The reasons underlying the persistence of primary closure are not quite evident in the literature.
Objective:
To present our experience with primary closure in CEA, and provide a rationale for its persistent wide use.
Methods:
Medical records of all patients undergoing CEA by the senior author (R.F.) were retrospectively reviewed. Follow-up was supplemented with a telephone interview and completion of a structured questionnaire. A review of the current literature was performed.
Results:
From 1998 to 2010, the senior author performed 111 CEAs. Average cross-clamp time was 33 ± 11 minutes. Postoperative complications included 1 non– ST-elevation myocardial infarction and 2 strokes. No deaths, cranial-nerve deficits, or acute reocclusions were observed. After a mean follow-up of 64.6 months (7170.6 case-months), there were 3 contralateral strokes and 7 deaths. There were no ipsilateral strokes or restenoses >50%. Follow-up medication compliance was 94.6% for anti-platelet agents and 91.9% for statins. The outcomes of the current study were comparable to those of the available trials comparing patch angioplasty with primary closure. A careful evaluation of the literature revealed a number of reasons potentially explaining the persistent use of patch angioplasty.
Conclusion:
In conjunction with contemporary medical management, primary closure during CEA may yield results comparable or superior to patch angioplasty. Advantages of primary closure include shorter cross-clamp times and elimination of graft-specific complications.
