Abstract
INTRODUCTION Hypothalamic invasion in pediatric patients with craniopharyngioma negatively influences clinical outcomes. It has been shown that radiologic classification of hypothalamic invasion can effectively predict surgical strategies to minimize postoperative comorbidities in pediatric patients. However, no comparative analysis has been performed in adult patients with craniopharyngioma. This study implements the previously established radiologic classification to characterize postoperative morbidity, surgical outcome, and distress in adult patients with craniopharyngioma. METHODS Electronic medical records of 22 adult patients with craniopharyngioma were used to analyze patient demographics, surgical data, endocrinologic and ophthalmologic status, and histopathology in a retrospective single-center study. Questionnaires regarding postoperative distress (National Comprehensive Cancer Network Distress Thermometer and Problem List), comorbidities (Charlson Comorbidity Index), employment status, and need for supportive care were distributed. Magnetic resonance imaging scans were categorized according to Puget et al. RESULTS Patients with hypothalamic involvement show significantly higher rates of postoperative diabetes insipidus and higher scores on the National Comprehensive Cancer Network Distress Thermometer. This significant difference was lost when considering postoperative Puget grades. Puget grades 1 and 2 were found to be associated with the use of a subfrontal surgical approach (hazard ratio, 4.080; confidence interval, 1.153-14.431; P = 0.029). CONCLUSIONS Our results point toward a possible predictive role of preoperative hypothalamic invasion for postoperative diabetes insipidus as well as higher perceived levels of distress after surgery, which may be established in larger patient cohorts. Furthermore, a subfrontal surgical approach seems to be predicted by tumors with hypothalamic invasion. In this case, preoperative magnetic resonance imaging grading may help guide the planning of an optimal surgical strategy for adults with craniopharyngioma to reduce postoperative morbidity.

Abstract
BACKGROUND Surgical access to hypothalamic pathologies can be challenging. Recent case series demonstrate that the transsphenoidal approach to the hypothalamus can be safe and effective, however, may not be feasible in all patients. This study aims to investigate the feasibility of the endonasal transsphenoidal suprasellar subchiasmatic (ETSS) approach to the hypothalamus through a radiological evaluation of the subchiasmatic corridor dimension in an adult population. METHODS A retrospective review of magnetic resonance imaging of the brain was performed on 164 consecutive adult patients at our institution, of which 100 patients were deemed eligible for inclusion. Measurements were obtained at the two narrowest points along the subchiasmatic corridor: the subchiamastic window, which is the face of the subchiasmatic corridor and the midpoint window, which is located in the middle of the subchiasmatic corridor. Based on defined parameters, including the subchasmiatic window width (SW), subchiasmatic window height (SH), midpoint window width (MW), and midpoint window height (MH), patients were dichotomised into groups: patients with subchiasmatic corridor measurements any dimension of less than 3 mm, or patients with dimensions greater than or equal to 3 mm. RESULTS A total of 72 (72%) of the study population had dimensions of equal to or greater than 3 mm throughout the entirety of the subchiasmatic corridor, making hypothalamic biopsy feasible through the ETSS route for these patients. CONCLUSION Based on a radiological evaluation of the subchiasmatic corridor dimension in an Australian adult population, the majority of the population are suitable to undergo an endonasal transsphenoidal suprasellar subchiasmatic biopsy of the hypothalamus.

Abstract
Background and Aim Contemporary management of hydrocephalus involves various modes of cerebrospinal fluid (CSF) diversion, including shunt surgery and endoscopic ventriculostomy. However, there are times when either of these procedures have either failed or are not feasible. Highly invasive procedures aimed at internal CSF have been described previously, which, with the aid of modern microsurgical techniques, can be attempted in cases with very limited options. Our aim was to study the utility of extra-axial third ventriculostomy via lamina terminalis fenestration with multiple cisternostomies in the treatment of failed hydrocephalus. Materials and Methods Forty-five patients with hydrocephalus were operated for extra-axial trans-lamina terminalis third ventriculostomy with multiple cisternostomies from January 2017 to January 2019. A minimally invasive supraorbital craniotomy was performed with subfrontal fenestration of the lamina terminalis and trans-lamina terminalis fenestration of the floor of the third ventricle with multiple cisternostomies including the optico-carotid cistern and opening of the Liliequist membrane. Results Tuberculous meningitis was the most common etiology in the series, and multiple shunt procedures and incompatible CSF profiles were the most common reasons that necessitated this alternate rescue procedure. At a mean follow-up of 6 months, no patient required a revision shunt surgery. There was one death due to cardiac failure with anasarca, unrelated to the procedure. Conclusions Extra-axial trans-lamina terminalis ventriculostomy with cisternostomies can safely be performed using minimally invasive micro-neurosurgical techniques, adding to the armamentarium of neurosurgeons in the management of complex cases of hydrocephalus.

Abstract
BACKGROUND Solitary intracranial hypothalamic mass occurs rarely. The etiological diagnosis of solitary hypothalamus lesion is challenging and often unachievable. Although previous studies indicated that lesions affecting the hypothalamus often cause significant metabolic disorders, few reports about the metabolic disturbances of patients with solitary hypothalamic mass have been reported. METHOD Twenty-five patients with solitary hypothalamus lesions who had been evaluated and treated in Huashan Hospital from January 2010 to December 2020 were retrospectively enrolled. The clinical manifestations, radiological features, endocrine and metabolic disorders, and pathology were analyzed. RESULTS The male to female ratio was 5/20. The median age of onset was 22 (19, 35) years old. The most common initial symptom was polydipsia/polyuria (19/25, 76.0%) and amenorrhea (9/20, 45.0%). A high prevalence of hypopituitarism of different axes was found, with almost all no less than 80%. Central hypogonadism (21/22, 95.5%) and central diabetes insipidus (19/21, 90.5%) were the top two pituitary dysfunctions. Conclusive diagnoses were achieved by intracranial surgical biopsy/resection or stereotactic biopsy in 16 cases and by examining extracranial lesions in 3 cases. The pathological results were various, and the most common diagnoses were Langerhans cell histiocytosis (7/19) and hypothalamitis (5/19). The mean timespan from onset to diagnosis in the 19 cases was 34 ± 26 months. Metabolic evaluations revealed remarkable metabolic disorders, including hyperlipidemia (13/16, 81.3%), hyperglycemia (10/16, 62.5%), hyperuricemia (12/20, 60%), overweight/obesity (13/20, 65.0%), and hepatic adipose infiltration (10/13, 76.6%). CONCLUSION Either surgical or stereotactic biopsy will be a reliable and relatively safe procedure to help to confirm the pathological diagnosis of solitary hypothalamic mass. Metabolic disorders were severe in patients with solitary hypothalamic mass. The management of such cases should cover both the treatment of the primary disease, as well as the endocrine and metabolic disorders.

Abstract
OBJECTIVE Several attempts have been done to capture damaged hypothalamus (HT) using volumetric measurements to predict the development of hypothalamic obesity in patients with craniopharyngioma (CP). This study was to develop a novel method of HT volume measurement and examine the associations between postoperative HT volume and clinical parameters in patients with CP. METHODS We included 78 patients with adult-onset CP who underwent surgical resection. Postoperative HT volume was measured using T1- and T2-weighted magnetic resonance imaging (MRI) with a slice thickness of 3 mm, and corrected for temporal lobe volume. We collected data on pre- and postoperative body weights, which were measured at the time of HT volume measurements. RESULTS The corrected postoperative HT volume measured using T1- and T2-weighted images was significantly correlated (r=0.51 [95% confidence interval (CI) 0.32 to 0.67], P<0.01). However, HT volume was overestimated using T1-weighted images owing to obscured MR signal of the thalamus in patients with severe HT damage. Therefore, we used T2-weighted images to evaluate its clinical implications in 72 patients with available medical data. Postoperative HT volume was negatively associated with preoperative body weight and preoperative tumor volume (r=-0.25 [95% CI -0.45 to -0.04], P=0.04 and r=-0.26 [95% CI -0.40 to -0.15], P=0.03, respectively). In the subgroup analysis of CP patients who underwent primary surgery (n=56), pre- and postoperative body weights were negatively associated with HT volume (r=-0.30 [95% CI -0.53 to -0.03], P=0.03 and r=-0.29 [95% CI -0.53 to -0.02], P=0.03, respectively). CONCLUSIONS Adult-onset CP patients showed negative associations between postoperative HT volume and preoperative/postoperative body weight using a new method of HT volume measurement based on T2-weighted images.

Abstract
The precise understanding of hypothalamic injury (HI) patterns and their relationship with different craniopharyngioma (CP) classifications remains poorly addressed. Here, four HI patterns after CP resection based on endoscopic observation were introduced. A total of 131 CP cases treated with endoscopic endonasal approach (EEA) were reviewed retrospectively and divided into four HI patterns: no-HI, mild-HI, unilateral-HI and bilateral-HI, according to intraoperative findings. The outcomes were evaluated and compared between groups in terms of weight gain, endocrine status, electrolyte disturbance and neuropsychological function before and after surgery. A systematic correlation was found between CP origin and subsequent HI patterns. The majority of intrasellar and suprasellar stalk origins lead to a no-HI pattern, the central-type CP mainly develops a mild or bilateral HI pattern, and the majority of tumors with hypothalamic stalk origins result in unilateral HI and sometimes bilateral HI patterns. The proportion of tumors with a maximum diameter >3 cm in the no-HI group was higher than that in the mild-HI group, BMI and quality of life in the no-HI group showed better results than those in the other groups. The incidence of new-onset diabetes insipidus in the bilateral-HI group was significantly higher than that in the other groups. Memory difficulty was observed mainly in the unilateral-HI and bilateral-HI groups. However, the outcomes of electrolyte disturbance, sleep, and cognitive disorder in the unilateral-HI group were significantly better than those in the bilateral-HI group. This study suggests the possibility of using pre- and intraoperative observation of CP origin to predict four HI patterns and even subsequent outcomes after tumor removal.

Abstract
Peripheral collateral vessel aneurysms in Moyamoya disease (MMD) remain difficult to treat due to their deep location, small size, and vascular fragility. We report the case of an aneurysm localized in the hypothalamus, which was rapidly increasing in size with repeated hemorrhage despite revascularization surgery. Aneurysm clipping was performed to prevent further progress and rerupture with favorable outcome. To our best knowledge, this is the first description of a hypothalamic aneurysm in MMD being clipped via a transcallosal, transchoroidal approach through the third ventricle.

Abstract
INTRODUCTION Craniopharyngiomas (CPs) are benign histological tumors that may develop at different positions along the hypothalamic-pituitary axis. Their close, heterogenous relationship to the hypothalamus makes surgical removal challenging even though this remains the primary treatment strategy. AREAS COVERED This article presents a critical overview of the pathological and clinical concepts regarding CPs that should be considered when planning treatment. Thus, we have performed a comprehensive review of detailed CP reports published between 1839 and 2020. EXPERT OPINION CP surgery should pursue maximal tumor resection while minimizing the risk of injuring the hypothalamus. Therefore, surgical strategies should be individualized for each patient. Accurate assessment of presenting symptoms and preoperative MRI has proven useful to predict the type of CP-hypothalamus relationship that will be found during surgery. CPs with dense and extensive adhesions to the hypothalamus should be highly suspected when MRI shows the hypothalamus positioned around the mid-third of the tumor and an amputated upper portion of the pituitary stalk. Symptoms related to functional impairment of the infundibulo-tuberal area of the third ventricle floor, such as obesity/hyperphagia, Fröhlich's syndrome, diabetes insipidus, and/or somnolence, also indicate risky CP-hypothalamic adhesions. In these cases, limited tumor removal is strongly advocated followed by radiation therapy.

Abstract
Aggressiveness has a high prevalence in psychiatric patients and is a major health problem. Two brain areas involved in the neural network of aggressive behavior are the amygdala and the hypothalamus. While pharmacological treatments are effective in most patients, some do not properly respond to conventional therapies and are considered medically refractory. In this population, surgical procedures (ie, stereotactic lesions and deep brain stimulation) have been performed in an attempt to improve symptomatology and quality of life. Clinical results obtained after surgery are difficult to interpret, and the mechanisms responsible for postoperative reductions in aggressive behavior are unknown. We review the rationale and neurobiological characteristics that may help to explain why functional neurosurgery has been proposed to control aggressive behavior.

Abstract
BACKGROUND Shunt-dependent hydrocephalus (SDH) is a common complication after aneurysmal subarachnoid hemorrhage and affects its outcome significantly. Whether fenestration of the lamina terminalis (FLT) during anterior circulation aneurysm clipping for aneurysmal subarachnoid hemorrhage can decrease the occurrence of SDH is still controversial. METHODS Ovid and PubMed databases were retrieved by the following key words: "hydrocephalus," "subarachnoid hemorrhage," "aneurysm," "fenestration," and "lamina terminalis." The Cochran-Mantel-Haenszel test was used to compare overall incidence of SDH. RESULTS The literatures were searched, and 15 were included involving 2839 patients. The overall incidence of SDH in fenestrated cohort was 11.4%, compared with 15.3% in the nonfenestrated cohort (P = 0.008). The relative risk of SDH in fenestrated cohort was 0.67 (95% confidence interval 0.50-0.90). CONCLUSIONS This meta-analysis suggests that FLT during anterior circulation aneurysm clipping reduces the incidence of SDH. However, a well-designed, randomized controlled trial is necessary to prove the efficacy of FLT to reduce SDH.

Abstract
INTRODUCTION Since, under certain circumstances, defensive or attacking behaviours display a pattern of motor dominance, as observed in subjects who participate in contact or fighting sports, aggressive behaviour was considered to have a dominant motor pattern. With the aim of preventing the functional problems reported with bilateral lesion procedures involving both the central nucleus of the amygdala and the posteromedial hypothalamus, the decision was made to combine them; thus, an amygdalotomy of the central nucleus of the amygdala and a posteromedial hypothalamotomy were to be performed simultaneously and unilaterally, on the basis of the motor dominance of the patient determined by means of the Edinburgh test. PATIENTS AND METHODS This study describes the surgical experience in a series of nine patients diagnosed with refractory neuroaggressive syndrome. As part of the study protocol, a magnetic resonance brain scan was performed to rule out the presence of neoplasms, vascular diseases, infections and degenerative disorders. The degree of aggressiveness was quantified using Yudofsky's Overt Aggression Scale. Additionally, manual dominance was determined by means of the Edinburgh test. RESULTS AND CONCLUSIONS Good control of aggressiveness was seen immediately. In some cases it was necessary to reduce the antipsychotic or benzodiazepine medication, as it was seen to increase aggressiveness. Only one case required a second surgical intervention. Follow-up was achieved in 100% of the cases at 24 months and 78% at 36 months.

Abstract
IMPORTANCE Deep brain stimulation (DBS) has been investigated for treatment of morbid obesity with variable results. Patients with Prader-Willi syndrome (PWS) present with obesity that is often difficult to treat. OBJECTIVE To test the safety and study the outcome of DBS in patients with PWS. DESIGN, SETTING, AND PARTICIPANTS This case series was conducted in the Hospital das Clínicas, University of São Paulo, Brazil. Four patients with genetically confirmed PWS presenting with severe obesity were included. EXPOSURE Deep brain stimulation electrodes were bilaterally implanted in the lateral hypothalamic area. After DBS implantation, the treatment included the following phases: titration (1-2 months), stimulation off (2 months), low-frequency DBS (40 Hz; 1 month), washout (15 days), high-frequency DBS (130 Hz; 1 month), and long-term follow-up (6 months). MAIN OUTCOMES AND MEASURES Primary outcome measures were adverse events recorded during stimulation and long-term DBS treatment. Secondary outcomes consisted of changes in anthropometric measures (weight, body mass index [calculated as weight in kilograms divided by height in meters squared], and abdominal and neck circumference), bioimpedanciometry, and calorimetry after 6 months of treatment compared with baseline. The following evaluations and measurements were conducted before and after DBS: clinical, neurological, psychiatric, neuropsychological, anthropometry, calorimetry, blood workup, hormonal levels, and sleep studies. Adverse effects were monitored during all follow-up visits. RESULTS Four patients with PWS were included (2 male and 2 female; ages 18-28 years). Baseline mean (SD) body mass index was 39.6 (11.1). Two patients had previous bariatric surgery, and all presented with psychiatric comorbidity, which was well controlled with the use of medications. At 6 months after long-term DBS, patients had a mean 9.6% increase in weight, 5.8% increase in body mass index, 8.4% increase in abdominal circumference, 4.2% increase in neck circumference, 5.3% increase in the percentage of body fat, and 0% change in calorimetry compared with baseline. Also unchanged were hormonal levels and results of blood workup, sleep studies, and neuropsychological evaluations. Two patients developed stimulation-induced manic symptoms. Discontinuation of DBS controlled this symptom in 1 patient. The other required adjustments in medication dosage. Two infections were documented, 1 associated with skin picking. CONCLUSIONS AND RELEVANCE Safety of lateral hypothalamic area stimulation was in the range of that demonstrated in patients with similar psychiatric conditions receiving DBS. In the small cohort of patients with PWS treated in our study, DBS was largely ineffective.

Abstract
BACKGROUND Assessment of presurgical hypothalamic involvement (psHI) and treatment-related hypothalamic damage (trHD) is relevant for the decision on risk-adapted treatment and rehabilitation strategies in craniopharyngioma. PATIENTS AND METHODS 129 surgical reports of childhood-onset craniopharyngioma patients recruited 2007-2014 in KRANIOPHARYNGEOM 2007 were analyzed. Data on psHI were available based on surgeon's (63%), reference neuroradiologist's (95%), and local radiologist's (23%) assessment. The surgical degree of resection (DoR) was assessed by neurosurgeon (95%), reference neuroradiologist (73%), and local radiologist (61%). TrHD was assessed by neurosurgeon (33%), by reference neuroradiologist (95%), and by local radiologist (2%). Neurosurgical center size was categorized based on patient load. RESULTS Surgical assessments on psHI (n = 78), DoR (n = 89) and trHD (n = 42) as documented in surgical reports could be compared with the assessment of respective parameters by reference neuroradiologist. Differences with regard to DoR (p = 0.0001) and trHD (p < 0.0001) were detectable between surgeon's and reference neuroradiologist's assessment, whereas psHI was assessed similarly. Concordance for DoR and trHD was observed in 48 and 62%, respectively. Surgeons estimated a higher rate of complete resections and a lower rate of trHD. Neuroradiological reference assessment of trHD had higher predictive value for hypothalamic sequelae then surgical assessment. Observed differences were not related to neurosurgical center size. CONCLUSIONS Observed differences between surgical and neuroradiological estimation of risk factors in craniopharyngioma support the necessity of neuroradiological reference review to assure standards of quality. This could be established by central internet-based neuroradiological review in KRANIOPHARYNGEOM 2007. Standardization of surgical reports including specific assessment of tumor/damage location is recommended.

Abstract
Resection of large lesions growing into the third ventricle is considered nowadays still a demanding surgery, due to the high risk of severe endocrine and neurological complications. Some neurosurgical approaches were considered in the past the procedures of choice to access the third ventricle, however they were burden by endocrine and neurological consequences, like memory loss and epilepsy. We report here the endocrine and functional results in a series of patients operated with a recently developed approach specifically tailored for the resection of large lesions growing into the third ventricle. Authors conducted a retrospective analysis on 10 patients, operated between 2011 and 2012, for the resection of large tumors growing into the third ventricle. Total resection was achieved in all patients. No perioperative deaths were recorded and all patients were alive after the follow-up. One year after surgery 8/10 patients had an excellent outcome with a Karnofsky Performance Status of 100 and a Glasgow Outcome score of 5, with 8 patients experiencing an improvement of the Body Mass Index. Modern neurosurgery allows a safe and effective treatment of large lesions growing into the third ventricle with a postoperative good functional status.

Abstract
OBJECTIVES The management of paediatric craniopharyngiomas was traditionally complete resection (CR), with better reported tumour control compared to that by partial resection (PR) or limited surgery (LS). The subsequent shift towards hypothalamic sparing, conservative surgery with adjuvant radiotherapy (RT) to any residual tumour aimed at reducing neuroendocrine morbidity, has not been systematically studied. Hence, we reviewed the sequelae of differing management strategies in paediatric craniopharyngioma across three UK tertiary centres over four decades. METHODS Meta-data was retrospectively reviewed over two periods before (1973-2000 (Group A: n = 100)) and after (1998-2011 (Group B: n = 85)) the introduction of the conservative strategy at each centre. RESULTS Patients had CR (A: 34% and B: 19%), PR (A: 48% and B: 46%) or LS (A: 16% and B: 34%), with trends reflecting the change in surgical approach over time. Overall recurrence rates between the two periods did not change (A: 38% vs B: 32%). More patients received RT in B than A, but recurrence rates were similar: for A, 28% patients received RT with 9 recurrences (32%); for B, 62% received RT with 14 recurrences (26%). However, rates of diabetes insipidus (P = 0.04), gonadotrophin deficiency (P < 0.001) and panhypopituitarism (P = 0.001) were lower in B than those in A. In contrast, post-operative obesity (BMI SDS >+2.0) (P = 0.4) and hypothalamic (P = 0.1) and visual (P = 0.3) morbidity rates were unchanged. CONCLUSION The shift towards more conservative surgery has reduced the prevalence of hormone deficiencies, including diabetes insipidus, which can be life threatening. However, it has not been associated with reduced hypothalamic and visual morbidities, which remain a significant challenge. More effective targeted therapies are necessary to improve outcomes.

Abstract
BACKGROUND Shunt-dependent hydrocephalus (SDH) is a well-known sequela following aneurysmal hemorrhage, adversely affecting the outcome after securing ruptured aneurysm. Fenestration of lamina terminalis (FLT) creates an anterior ventriculostomy, facilitates cerebrospinal fluid circulation and clot clearance in the basal cistern. However, controversy exists over whether microsurgical FLT during aneurysm repair can decrease the incidence of SDH. AIMS The study is designed to determine the efficacy of lamina terminalis fenestration on the reduction of SDH after aneurysm clipping. METHODS/DESIGN A total of 288 patients who meet the inclusion criteria will be randomized into single aneurysm clipping or aneurysm clipping plus FLT in the Department of Neurosurgery, West China Hospital. Follow-up was performed 1, 3, 6, and 12 months after aneurysm clipping. The primary outcome is the incidence of SDH and the secondary outcomes include cerebral vasospasm, functional outcome evaluated by the modified Rankin Scale and Extended Glasgow Outcome Scale, and mortality. DISCUSSION The FISH trial is a large randomized, parallel controlled clinical trial to define the therapeutic value of FLT, the results of which will help to guide the surgical procedure and resolve the long-puzzled debate in the neurosurgical community. CONCLUSIONS This protocol will determine the efficacy of FLT in the setting of aneurysmal subarachnoid hemorrhage. TRIAL REGISTRATION IDENTIFIER CHINESE CLINICAL TRIAL REGISTRY:: ChiCTR-INR-16009249.

Abstract
OBJECTIVE To investigate the techniques and effect of surgical resection of large intra- and extra-ventricular craniopharyngiomas via anterior interhemispheric trans-lamina terminalis approach. METHODS Fifty-two patients who were surgically treated for large intra- and extra-ventricular craniopharyngiomas were retrospectively analyzed. All patients underwent surgery via anterior interhemispheric trans-lamina terminalis approach. Of the 52 patients, 28 were male and 24 were female, with age ranging from 3 to 67 years (mean age 33.5 years). The maximum tumor diameter varied from 4.0 to 7.8 cm, with mean diameter of 5.1 cm. Contrast-enhanced MRI was underwent to determine the extent of tumor resection on the 1 to 3 months after surgery. RESULTS Total removal of the lesion was achieved in 47 cases (90.4%), 5 patients underwent subtotal resection (9.6%). Division of the anterior communicating artery was performed in 6 patients with no early or late complications related to division of the artery. Visual acuity was preserved or improved in 44 patients (84.6%). Preservation of the pituitary stalk were achieved in 33 patients (63.5%). No surgery-related deaths occurred. The postsurgical follow-up period varied from 3 months to 68 months (mean 25.4 months). Twenty-three cases had endocrinological deficit and received some form of hormonal replacement after surgery. Permanent diabetes insipidus occurred in 18 cases. Three patients died and 6 patients suffered recurrence during the followed-up period. CONCLUSIONS The anterior interhemispheric approach, with opening of the lamina terminalis, is a valid choice for large intra- and extra-ventricular craniopharyngiomas. These tumors can be removed without significant sequelae related to the surgical approach because optic nerves, optic chiasm, internal carotid artery, hypothalamic structures and pituitary stalk can be seen and effectively protected.

Abstract
CONTEXT Craniopharyngioma is a brain tumor whose high local recurrence rate has for a long time led to a preference for extensive surgery. Limited surgery minimizing hypothalamic damage may decrease the severe obesity rate at the expense of the need for radiotherapy to complete the treatment. OBJECTIVE We compared weight gain and local recurrence rates after extensive resection surgery (ERS) and hypothalamus-sparing surgery (HSS). DESIGN Our observational study compared a historical cohort managed with ERS between 1985 and 2002 to a prospective cohort managed with HSS between 2002 and 2010. SETTING The patients were treated in a pediatric teaching hospital in Paris, France. PATIENTS Thirty-seven boys and 23 girls were managed with ERS (median age, 8 years); 38 boys and 27 girls were managed with HSS (median age, 9.3 years). MAIN OUTCOME MEASURES Data were collected before and 6 months to 7 years after surgery. Body mass index (BMI) Z-score was used to assess obesity and the number of surgical procedures to assess local recurrence rate. RESULTS Mean BMI Z-score before surgery was comparable in the 2 cohorts (0.756 after ERS vs 0.747 after HSS; P = .528). At any time after surgery, mean BMI Z-score was significantly lower after HSS (eg, 1.889 SD vs 2.915 SD, P = .004 at 1 year). At last follow-up, the HSS cohort had a significantly lower prevalence of severe obesity (28% vs 54%, P < .05) and higher prevalence of normal BMI (38% vs 17%, P < .01). Mean number of surgical procedures was not significantly different in the 2 cohorts. CONCLUSIONS Hypothalamus-sparing surgery decreases the occurrence of severe obesity without increasing the local recurrence rate.

Abstract
CONTEXT Hypernatremia is encountered after pituitary or hypothalamic surgery and typically is secondary to vasopressin deficiency resulting in increased free water clearance with inadequate water replacement. OBJECTIVE We report a type 2 diabetic patient with severe hypernatremia (Na⁺ = 161 mEq/L) after hypothalamic surgery. Unexpectedly, this was accompanied by persistent urinary hypertonicity and negative total but positive electrolyte free water clearance. MAIN OUTCOME MEASURE Measurement of urinary electrolytes and urea revealed that an osmotic diuresis induced by urea derived principally by breakdown of endogenous protein was causative. Body protein losses over 48 hours were estimated to exceed 2 kg of lean mass. High-dose glucocorticoid, insulin resistance, and a postsurgical catabolic stress likely contributed. CONCLUSION In surgically severely stressed individuals, proteolysis of endogenous protein can strongly impact body water metabolism and contribute to severe hypernatremia.

Abstract
BACKGROUND Surgical treatment of large exophytic chiasmatic/hypothalamic astrocytomas extending into the anterior third ventricle remains a challenging task for neurosurgeons. In particular, when the tumor extends from the chiasmatic region upward to the foramen of Monro, damage to the fornix and other neurovascular structures is a major concern. OBJECTIVE To describe the technique used in the transventricular preforniceal surgical approach to remove the superior and superoposterior part of the tumor in the third ventricle for treatment of exophytic chiasmatic/hypothalamic astrocytoma. METHODS The transventricular preforniceal approach was used in two cases of exophytic chiasmatic/hypothalamic astrocytoma. The approach is summarized in 4 procedures: 1) exposure of the anterior horn of the lateral ventricle by the transcallosal approach, 2) identification of the foramen of Monro and the fornix, 3) incision of the septum pellucidum or the wall of the lateral ventricle, in front of the columns of the fornix, and 4) removal of the tumor through the space between the anterior commissure and the columns of the fornix. RESULTS Because the tumor compressed the foramen of Monro posteriorly and stretched the space between the anterior commissure and the columns of the fornix, the posterosuperior part of the tumor in the third ventricle was successfully removed through the surgical corridor in front of the columns of the fornix. In both cases, tumors were successfully removed using this approach without damaging the fornix and the anterior commissure. Residual tumor was removed using an anterior interhemispheric translamina terminalis approach in a two-stage surgery. CONCLUSIONS The transventricular preforniceal approach can be applied for removing the superior part of exophytic chiasmatic/hypothalamic astrocytomas, because the space between the anterior commissure and the fornix is stretched by the tumor, providing an appropriate surgical corridor.

Abstract
BACKGROUND Opening of the lamina terminalis is often used in surgery of the optico-chiasmatic region. Consequently, alteration of cerebral-spinal fluid (CSF) dynamics can occur after this manoeuvre, thus potentially translating into clinical complications. Herein, we describe 2 cases in which clinically relevant hypothalamic dysfunctions developed after few days opening of the lamina terminalis both patients showed mild to moderate preoperative hydrocephalus which improved postoperatively. CASES DESCRIPTION In a patient with ruptured aneurysm of the basilar bifurcation, opening of the lamina terminalis was performed prior to acute-stage clipping. On postoperative day 7th, the patient developed significant subdural hygroma, mild disturbances of consciousness and increase of ADH concentration. These clinical features resolved only following subdural hygroma drainage and ventricular-peritoneal shunting. One previously operated patient in whom the lamina terminalis had been opened to remove a sizeable parasellar tumour showed a similar post-operative course. In this patient, sole subdural hygroma drainage was not an effective treatment, and the patient died subsequently for complications related to long-standing, though mild, hypothalamic dysfunction. CONCLUSIONS Our experience may suggest that hypothalamic dysfunctions should be reminded as a possible, although rare, complication following the opening of the lamina terminalis. This clinical condition, if not properly managed, may contribute to trigger severe life-threatening complications.

Abstract
BACKGROUND Hypothalamic obesity has major impact on prognosis and quality of life (QoL) in childhood craniopharyngioma. PATIENTS AND METHODS For this study, 120 patients were prospectively recruited during 2001 and 2007 and evaluated after 3 years of follow-up (KRANIOPHARYNGEOM 2000). Body mass index (BMI) and QoL at diagnosis and 36 months after diagnosis were analysed based on the reference assessment of tumour localisation and post-surgical hypothalamic lesions. Treatment was analysed based on the neurosurgical strategy of 50 participating neurosurgical centres, the centre size based on the patient load. RESULTS BMI SDS at diagnosis was similar in patients with or without hypothalamic involvement. Surgical lesions of anterior and posterior hypothalamic areas were associated with higher increase in BMI SDS during 36 months post-diagnosis compared with patients without or only anterior lesion (+1.8 BMISD, P=0.033, +2.1 BMISD; P=0.011), negative impact on QoL in patients with posterior hypothalamic lesions. Surgical strategies varied among the 50 neurosurgical centres (three large-sized, 24 middle-sized and 23 small-sized centres). Patients treated in small-sized centres presented with a higher rate of hypothalamic involvement compared with those treated in the middle- and large-sized centres. Treatment in large-sized centres was less radical, and the rates of complete resection and hypothalamic surgical lesions were lower in large-sized centres than those of the middle- and small-sized centres. However, a multivariable analysis showed that pre-operative hypothalamic involvement was the only independent risk factor for severe obesity (P=0.002). CONCLUSIONS Radical neurosurgical strategies leading to posterior hypothalamic lesions are not recommended due to the potential to exacerbate hypothalamic obesity and impaired QoL. Treatment should be confined to experienced multidisciplinary teams.

Abstract
Recent clinical studies show that the atypical antipsychotic medication, quetiapine, may be beneficial in the treatment of substance abuse by alleviating the withdrawal-negative affect stage of addiction. Since the effect of quetiapine on central reward function is largely unknown we studied its effects on brain stimulation reward in animals under withdrawal from escalating doses of d-amphetamine. Male Sprague-Dawley rats were trained to produce an operant response to receive a short train of electrical stimulation to the lateral hypothalamus. Measures of reward threshold were determined with the curve-shift method in different groups of rats before, and during four days after treatment with escalating doses (1 to 10mg/kg, i.p.) of d-amphetamine or its vehicle. At 24h of withdrawal, the effects of two doses of quetiapine (2 and 10mg/kg i.p.) were tested. Animals treated with d-amphetamine showed a 25% reward deficit at 24h of withdrawal, an effect that decreased progressively over the next three days. Quetiapine attenuated reward in the vehicle-control animals, and amplified the anhedonia at the moderate, but not the low, dose in the animals under withdrawal. These results show that acute treatment with clinically relevant doses of quetiapine for the treatment of schizophrenia may exacerbate anhedonia induced by amphetamine withdrawal. Further research should investigate whether repeated treatment with quetiapine has the ability to reverse amphetamine withdrawal-induced anhedonia.

Abstract
AIM We describe the clinical features, treatment and prognosis in a series of patients with epilepsy secondary to hypothalamic hamarthomas (HH) in a developing country. MATERIALS AND METHODS Eight patients with epilepsy and HH were included between 1997 and 2006. We analyzed gender, age, age at seizure onset (ASO), seizure types (ST), mental retardation (MR), precocious puberty (PP), electroencephalogram (EEG)-magnetic resonance imaging (MRI) features and response to treatment. RESULTS Mean age 25.1 years, 2/6 female/male, none had PP, ASO 4.5 years. Complex partial seizure were the most frequent (100%), mean similar to those seen in temporal (62.5%) or frontal lobe epilepsy (37.5%). Exactly 87.5% developed gelastic seizures (GS). Half of the patients showed MR. Mild-to-severe MR was associated with the presence of multiple ST including atonic and complex partial seizures with frontal semiology. Interictal EEG was abnormal in 87.5% patients. Video EEG was performed in three cases with unspecific findings. HH were small and sessile in seven patients whereas large and pedunculated in one. All patients were refractory to medical treatment. In five, an additional procedure was performed without any significant improvement. CONCLUSION These series show the heterogeneous spectrum of this entity and the difficulties in its treatment in a developing country.

Abstract
Gelastic seizures are an extremely rare form of epilepsy defined as automatic bouts of laughter without mirth commonly associated with a hypothalamic hamartoma. The objective was to survey all Israeli children found to develop recurrent gelastic seizures and report presenting symptoms, electroencephalographic and radiologic data, and response to either antiepileptic drugs or surgery. Ten children who developed gelastic seizures at the age of 1 week to 6.5 years (mean, 25 months) at a frequency from 3 bouts per week to >10 prolonged bouts per day were followed for a period of 1.3-12 years (mean, 6 years). Seven cases were defined as symptomatic: cortical magnetic resonance imaging revealed a hypothalamic hamartoma in four patients and cortical abnormalities in three others. Seizure control was achieved in four patients, including a neonate with status gelasticus and hypothalamic hamartoma, and partial control in one more. Five children remained resistant to polytherapy, including three with hypothalamic hamartoma even after two of them underwent hemartoma excision. Thus, children with gelastic seizures may respond relatively well to drug therapy. Four of the 10 patients became seizure free with drug therapy; in three intractable symptomatic cases, surgery was tried but failed in two of the three.

Abstract
Atrial natriuretic peptide-synthesizing neurons in the hypothalamic paraventricular nucleus constitute the major sources of ANP in the three lobes of the pituitary gland. Complete transection of the pituitary stalk eliminated 93% of ANP from the intermediate lobe, 47 and 77% from the anterior and the posterior lobes, respectively. Meantime, increased levels of immunoreactive ANP were measured in the median eminence, due to the accumulation of the peptide in the transected axons centrally to the transected stalk and in the paraventricular nucleus. It is likely that ANP neurons in the paraventricular nucleus innervate the pituitary, but those in the periventricular (median) preoptic nucleus and the organum vasculosum laminae terminalis may not contribute to the ANP innervation of the pituitary gland.

Abstract
PURPOSE To present the results of transcallosal surgical resection of hypothalamic hamartoma (HH) in 26 patients with refractory epilepsy in a prospective outcome study. METHODS Patients with refractory epilepsy symptomatic to HH were referred for surgical resection of their HH (mean age, 10.0 years; range, 2.1-24.2 years). A transcallosal, interforniceal approach was used to remove and/or disconnect the hamartoma. Volumetry was obtained on pre- and postoperative brain MRI scans to determine percentage of resection. Outcome assessment included determination of postoperative seizure frequencies in comparison to baseline and the incidence of postoperative complications. Postoperative changes in cognitive and behavioral functioning, in comparison to baseline, were elicited by parental report. RESULTS The average postoperative follow-up interval was 20.3 months (range, 13-28 months). Fourteen (54%) patients were completely seizure free, and nine (35%) had at least a 90% improvement in total seizure frequency. Parents reported postoperative improvement in behavior in 23 (88%) patients and in cognition in 17 (65%) patients. Transient postoperative memory disturbance was seen in 15 (58%) patients, but persisted in only two (8%). Two (8%) patients had persisting endocrine disturbance requiring hormone replacement therapy (diabetes insipidus and hypothyroidism in one each). With univariate analysis, the likelihood of a seizure-free outcome correlated with younger age, shorter lifetime duration of epilepsy, smaller preoperative HH volume, and 100% HH resection. CONCLUSIONS Refractory epilepsy associated with HH can be safely and effectively treated with surgical resection by a transcallosal, interforniceal approach. Short-term memory deficits appear to be transient for most patients, and family perception of the impact of surgery on cognitive and behavioral domains is favorable. Complete resection yields the best result.

Abstract
A 19-year old female with intractable gelastic seizures was found to have 0.7 x 1.8 x 1.8 cm elliptical mass on the floor of the third ventricle. The signal intensity on the Magnetic Resonance Imaging (MRI) was consistent with the Hypothalamic Hamartoma (HH). Ictal EEG demonstrated rhythmic 7 Hz waves over Fp2, F4, and C4 with spreading to the right temporal region and then bilaterally. Ictal Single Photon Emission Computerized Tomography (SPECT) showed hyperperfusion at hypothalamic and medial frontopolar regions. The patient underwent surgical resection using Trans Callosal Subchoroidal Approach (TCSA) to the third ventricle. Pathological finding confirmed the diagnosis of hypothalamic hamartoma. Following the operation, she has been seizure free up to 12 months. Thereafter, provoked seizures seldom occurred and there has been improvement in her memory, emotional control and independence. This appears to be the first report of this surgical approach for HH, which is less likely to disturb memory function compared to previously described interfoniceal approach.

Abstract
BACKGROUND The incidence of chronic hydrocephalus requiring shunt placement is a well-known and common complication of aneurysmal subarachnoid hemorrhage (aSAH). It was suggested that fenestration of the lamina terminalis (LT) during microsurgery for aSAH may be associated with a reduced rate of shunt-dependent chronic hydrocephalus (SDCH). We analyzed that, fenestrations of the LT and Liliequist membrane (LM) would reduce rate of SDCH and improve rate of favorable outcome. METHODS 145 patients who were analyzed in the study were treated in our department with ruptured anterior communicating artery (ACoA) aneurysms. We compared the rate of shunting and clinical outcome in patients in whom only fenestration of the LT (Group 1) was performed with that in patients in whom fenestrations of both the LT and LM (Group 2) were performed. RESULTS Chronic hydrocephalus requiring shunting amounted to 9.8% (7 patients) in Group 1 and 4% (3 patients) in Group 2 (p=0.203). Also, there were no differences in the rate of shunt dependent hydrocephalus between the two groups in patients with Fisher's CT grades 3 (p=0.343) and 4 (p=0.667), and HH grades 4 (p=0.306) and 5 (p=0.361). Favorable clinical outcomes were observed with rates of 74.6% in Group 1 and 79.7% in Group 2 (p=0.693). Also there were no differences in the rates of favorable clinical outcome between the two groups in patients with Fisher's CT grades 3-4, HH grades 4-5. CONCLUSIONS Our study shows that fenestration of the LM coupled with the opening of the LT reduced-relatively-the incidence of SDCH; this however was not significant. This positive effect was particularly noticeable in patients in whom a cisternal "overflow" was observed at surgery when opening the LM. This corresponded to cases with ventricular dilatation and a IVth ventricle with clots.

Abstract
Myxopapillary ependymomas (ME) are considered benign tumours (WHO grade I) of the central nervous system with long term survival rates and a tendency to local recurrence. However an aggressive course has occasionally been described, leading to CSF dissemination and even systemic metastases. We describe the case of a 23-year-old man diagnosed with intracranial subarachnoid dissemination of a filum terminale ME three years after the initial diagnosis. We have performed a careful review of the literature on CSF dissemination in ME and finally propose treatment of these cases.

Abstract
BACKGROUND AND PURPOSE Pilocytic astrocytoma (PA) is a WHO grade I tumor of the central nervous system mostly arising in children and young adults. Management of diencephalic PA is a difficult challenge. Surgical treatment has to cope with both the difficulties of deep location and eloquent area tumors. MATERIALS AND METHODS We retrospectively reviewed seven pediatric cases (female: 4, male: 3) of diencephalic PA. Opto-chiasmatic tumors were excluded from the series. Mean age at diagnosis was 108 months (9 years) (range: 4 month-18 years), median age was 111 months. Median follow-up for the series was 125 months. Tumor locations were as followed: right thalamus: 2, both thalami: 1, hypothalamus: 3, and right basal ganglia: 1. At the onset, the first symptom was mostly raised intracranial pressure. The delay in diagnosis ranged from 48 hours up to 6 years. TREATMENT a shunting procedure was performed in 3 patients, a direct surgical approach in 5 patients (gross total removal: 2; partial removal: 3) and one patient had only a biopsy. Three children were re-operated. Three patients were treated by radiationtherapy (RT) after surgery. Chemotherapy was delivered for 4 children. RESULTS The overall survival rate was 71.4 months (almost 6 years) (range: 3-184 months). Median survival rate was 42 months (3.5 years). Three children died, two by tumor progression and one death related to late side-effects of RT. Four patients have a good quality of life with GOS I (n = 3) or II (n = 1). We observed tumor regression in two patients at 1 and 17 years after the beginning of treatment. Correct diagnosis was only made for two cases at the initial pathological examination. CONCLUSION The course of diencephalic PA is still unpredictable. The tumor can be controlled by a partial surgical removal, and a residual tumor can sometimes decrease in size after surgery. Gross total removal of these tumors, although difficult, may be performed. With cranial navigation systems, the risk is low. Pathological diagnosis is sometimes difficult to assess.

Abstract
Recently, it was reported that fenestration of the lamina terminalis (LT) may reduce the incidence of shunt-dependent hydrocephalus in aneurysmal subarachnoid hemorrhage (SAH). The authors investigated the efficacy of the LT opening on the incidence of shunt-dependent hydrocephalus in the ruptured anterior communicating artery (ACoA) aneurysms. The data of 71-ruptured ACoA aneurysm patients who underwent aneurysmal clipping in acute stage were reviewed retrospectively. Group I (n=36) included the patients with microsurgical fenestration of LT during surgery, Group II (n=35) consisted of patients in whom fenestration of LT was not feasible. The rate of shunt-dependent hydrocephalus was compared between two groups by logistic regression to control for confounding factors. Ventriculo-peritoneal shunts were performed after aneurysmal obliteration in 18 patients (25.4%). The conversion rates from acute hydrocephalus on admission to chronic hydrocephalus in each group were 29.6% (Group I) and 58.8% (Group II), respectively. However, there was no significant correlation between the microsurgical fenestration and the rate of occurrence of shunt-dependent hydrocephalus (p>0.05). Surgeons should carefully decide the concomitant use of LT fenestration during surgery for the ruptured ACoA aneurysms because of the microsurgical fenestration of LT can play a negative role in reducing the incidence of chronic hydrocephalus.

Abstract
A 41-year-old woman presented with an unusual case of benign astrocytoma with marked pleomorphism manifesting as consciousness disturbance due to intraventricular hemorrhage. Magnetic resonance imaging revealed a well-enhanced hypothalamic mass protruding into the third ventricle. Despite partial resection of the tumor without additional therapy, there have been no signs of tumor regrowth for 6 years. The histological findings revealed solid proliferation of tumor cells with marked pleomorphism, contrary to the benign clinical course. However, no mitosis, necrosis, or endothelial proliferation were found and the MIB-1 index was less than 0.5%. Immunohistochemical staining indicated the glial origin of the tumor. The tumor was similar to pleomorphic xanthoastrocytoma, but the histological findings were not exactly identical, indicating a new histological entity.

Abstract
The hypothalamic hamartoma (HH) is a rare developmental malformation often characterized by gelastic seizures, which are usually refractory to medical therapy. The mechanisms of epileptogenesis operative in this subcortical lesion are unknown. In this study, we used standard patch-clamp electrophysiological techniques combined with histochemical approaches to study individual cells from human HH tissue immediately after surgical resection. More than 90% of dissociated HH cells were small (6-9 microm soma) and exhibited immunoreactivity to the neuronal marker NeuN, and to glutamic acid decarboxylase, but not to glial fibrillary acidic protein. Under current-clamp, whole-cell recordings in single dissociated cells or in intact HH slices demonstrated typical neuronal responses to depolarizing and hyperpolarizing current injection. In some cases, HH cells exhibited a "sag-like" membrane potential change during membrane hyperpolarization. Interestingly, most HH cells exhibited robust, spontaneous "pacemaker-like" action potential firing. Under voltage-clamp, dissociated HH cells exhibited functional tetrodotoxin (TTX)-sensitive Na(+) and tetraethylammonium-sensitive K(+) currents. Both GABA and glutamate evoked whole-cell currents, with GABA exhibiting a peak current amplitude 10-fold greater than glutamate. These findings suggest that human HH tissues, associated with gelastic seizures, contained predominantly small GABAergic inhibitory neurons that exhibited intrinsic "pacemaker-like" behavior.

Abstract
Hypothalamic hamartomas are rare developmental malformations of the inferior hypothalamus. Typically they result in symptomatic, refractory mixed seizure disorder with trademark gelastic or laughing seizures. We present a 30-month-old boy with a hypothalamic hamartoma and a nearly 2-month history of near-continuous gelastic seizures, which we have labeled "status gelasticus." The seizures were refractory to multiple antiepileptic drugs (AEDs), and emergency transcallosal resection of the hypothalamic hamartoma was performed with resultant near-immediate cessation of the seizures. At 12-month follow-up, the patient was averaging one brief gelastic seizure every 2 weeks, with a longest seizure-free period of 2 months.

Abstract
To determine secretory patterns of growth hormone-releasing hormone (GHRH) and somatostatin (SS) and their roles in the regulation of growth hormone (GH) secretion, a method for collecting hypothalamic perfusates, a push-pull perfusion method was developed in calves. With the use of the stereotaxic apparatus for cattle, a cannula was implanted into the hypothalamus of four male calves based upon cerebral ventriculography. Push-pull perfusates were collected at 10 min intervals for 6h and GHRH and SS concentrations in perfusates and plasma GH concentration were determined by EIAs and RIA, respectively. A cannula was implanted into the hypothalamus based on the image of the third ventricle and maintained for 1 month. GHRH and SS showed pulsatile secretion and the pulses for GHRH and SS were irregular in conscious animals. Neither GHRH nor SS secretion had a clear relationship with GH secretion. In the present study, we thus (1) established a stereotaxic technique for approaching the hypothalamus using cerebral ventriculography for calves, and (2) demonstrated that GHRH and SS secretion were pulsatile but not closely related to GH profile in conscious calves. The technique is useful for the study of the functions of the hypothalamus in the control of pituitary hormones in cattle.

Abstract
OBJECTIVE Drug resistant epilepsy associated with hypothalamic hamartoma (HH) can be cured by microsurgical resection of the lesion. Morbidity and mortality risks of microsurgery in this area are significant. Gamma Knife Surgery's (GKS) reduced invasivity seems to be well adapted. In view of the severity of the disease and risks of surgical resection it is crucial to evaluate GKS for this indication. A first retrospective study has shown a very good safety and efficacy level but for a more reliable evaluation a prospective study would be required. METHODS Between Oct 1999 and July 2002, 30 patients with HH and associated severe epilepsy were included. Seizure semiology (video EEG) and frequency, behavioural disturbances, neuropsychological performance, endocrinological status, sleep electroclinical abnormalities, MR imaging, and visual function were systematically evaluated before and after GKS (6, 12, 18, 24, 36 months). Twenty patients had experienced precocious puberty at a median age of 3,7 (0-9). Range of maximum diameter was from 7,5 to 23 mm with only 3 larger than 18 mm. The median marginal dose was 17 gy (14-20). RESULTS Sufficient follow up for final evaluation is not yet available. Only 6 patients have a follow-up of more than 12 months and 19 more than 6 months. However a lot of very dramatic changes did occur during that period in this group. Among the 19 patients with more than 6 months of follow-up, a lot had already experienced an increase of gelastic seizures around 3 months (3), an improvement in their seizure rate (18), behaviour (9), sleep (3), and EEG background activity (3), a cessation of partial complex seizures (7). No complications have occurred till now except one patient experiencing at 5 months a hyperthermia without infection and concomitant increase of gelastic seizures both ceasing suddenly and spontaneously after 15 days. CONCLUSION Our first results indicate that GKS is as effective as microsurgical resection and very much safer. GKS also allows to avoid the vascular risk related to radiofrequency lesioning or stimulation. The disadvantage of radiosurgery is its delayed action. Longer follow-up is mandatory for a serious evaluation of the role of GKS. Results are faster and more complete in patients with smaller lesions inside the 3rd ventricle (grade II). The early effect on subclinical discharges turns out to play a major role in the dramatic improvement of sleep quality, behaviour, developmental acceleration at school.

Abstract
OBJECT Hypothalamic hamartoma is a nonneoplastic malformative mass of neurons and glia in the region of the hypothalamus. Because of its location, open surgery is associated with high morbidity and mortality rates. Gamma knife surgery (GKS) may be an efficient and safe treatment approach, which produces little morbidity. The authors describe the results of GKS in three patients with hypothalamic hamartomas. METHODS All patients were male, aged 3, 12, and 15 years. The lesions were classified according to the Valdueza scale: one was Type IIb and two were Type IIa. The patients presented with gelastic seizures (15-20 per day), generalized epilepsy, behavioral abnormalities, and alterations of the sleep cycle. Precocious puberty was present in one patient. The Type IIb tumor had a volume of 1.8 cm3, and the Type IIa tumors were 597 mm3 and 530.1 mm3. The lesions received 12.5 Gy, 14 Gy, and 15 Gy, respectively, to the 50% isodose line. The patients were followed for 30 to 50 months. After 3 months, all patients showed improvement of their sleep, behavior, and epilepsy. At the present time, these patients are receiving low-dose antiepileptic agents and have achieved adequate social development and school integration. CONCLUSIONS Gamma knife surgery appears to be a good, safe, and effective option for the treatment of selected hypothalamic hamartomas. No morbidity or mortality was associated with these three cases.

Abstract
OBJECTIVE The aim of this study was to evaluate the effect on body weight set point over time of focused, subnecrotic doses of radiation via gamma knife (GK) to the hypothalamus of the genetically obese Zucker rat. METHODS A total of 36 adolescent animals were used in this experiment and placed in 6 groups of 6. The genetically obese homozygous Zucker rat was used in 4 groups (n = 24) and received GK, subcutaneous cobalt protoporphyrin (CoPP), both treatments combined or sham treatment. The heterozygous lean Zucker rat was used in 2 control groups (n = 12) and received either GK or sham treatment. All animals were weighed at the beginning of the experiment and at weekly intervals for 34 weeks. GK irradiation was accomplished using a specially designed stereotactic frame and a total dose of 40 Gy was given to 2 nearby targets in the medial hypothalamus. The drug subgroups received weekly subcutaneous injections. All animals were housed in the same environment with unlimited access to food. RESULTS There were no significant differences in weight between the lean GK and sham groups. For the obese cohort, beginning at week 7 and throughout the remainder of the experiment, there were significant and sustained reductions in weight set point for animals that received GK (p < 0.05) and CoPP (p < 0.05) compared to sham-treated animals. Curiously, there was no statistical difference between the combined treatment and sham subgroups, though there was a trend toward weight reduction (p < 0.10). With the exception of one animal in the obese GK cohort in which there was a small area of necrosis lateral to the target area, histopathological analysis failed to reveal any abnormalities. There were no gross behavioral abnormalities noted. CONCLUSION Our experimental results suggest that a single dose of GK irradiation to the hypothalamus can produce sustained reduction in the weight set point without emaciation in adolescent animals. The effect of this treatment is comparable to a well-studied drug therapy with a metalloporphyrin. We hypothesize that this involves a resetting of the hypothalamic set point for body weight through an as yet uncharacterized neuromodulatory effect.

Abstract
Abstract
OBJECTIVE:
Hydrocephalus, vasospasm, and frontobasal injury are common complications after aneurysmal subarachnoid hemorrhage (SAH) from anterior communicating artery aneurysms. Previous studies have suggested that fenestration of the lamina terminalis (FLT) during surgery may be associated with reduced rates of shunt-dependent hydrocephalus and vasospasm. We report 106 patients affected by anterior communicating artery aneurysms and Fisher Grade 3 aneurysmal SAH and the affect of FLT on shunt-dependent hydrocephalus, vasospasm, and frontobasal injury.
METHODS:
During a 3-year period, 53 patients underwent FLT and 53 did not. We prospectively evaluated admission and discharge clinical grades, hydrocephalus at admission, occurrence of clinical vasospasm, need for interventional vasospasm therapy, frontobasal hypodensity incidence, and permanent ventriculoperitoneal shunting requirement. Follow-up ranged from 3 to 35 months (mean, 17.9 mo).
RESULTS:
Shunting incidence after aneurysmal SAH with hydrocephalus was 4.25% in patients who underwent FLT and 13.9% in patients who did not (P< 0.001). Clinical cerebral vasospasm occurred in 29.6% of patients who underwent FLT and in 54.7% of patients who did not (P< 0.001). Frontobasal hypodensity was identified postoperatively in 0% of patients who underwent FLT and in 5% of patients who did not. Good outcome was reported in 69.81% of patients who underwent FLT and in 33.96% of patients who did not (P< 0.001). Poor outcome was associated with higher Hunt and Hess grades, need for ventricular drainage, elevated intracranial pressure, and multiple interventional vasospasm therapies. No complications were linked to FLT.
CONCLUSION:
FLT was associated with statistically significant decreases in shunting rates, incidence of vasospasm, and better outcomes. We recommend its routine use in patients with Fisher Grade 3 anterior communicating artery aneurysmal SAH.

Abstract
Although intractable epilepsy associated with hypothalamic hamartoma (HH) can be controlled by microsurgical resection of the lesion, excision of deep-seated lesions is often associated with morbidity and mortality. Endoscopic disconnection is less invasive and seems to be well suited for this indication. The authors discuss the role of endoscopic-assisted surgery in the management of HH-induced seizures. Four patients with HH-related intractable gelastic seizure underwent endoscopic disconnection surgery. Postoperatively, all patients exhibited improvement. Two patients became seizure free immediately after endoscopic disconnection surgery, one patient with a widespread seizure focus involving the motor strip continued to experience rare complex partial seizures but gelastic seizures ceased, and one experienced a reduced frequency of seizures but persistence of some generalized seizures. Three patients suffered postoperative disconnection-like syndrome, which continued 3 to 7 days and spontaneously disappeared. The authors advocate the endoscopic disconnection surgery as a safe and effective treatment for HH-related epilepsy by blocking the spread of epileptic discharges from the lesion.

Abstract
We describe two cases of hypothalamic hamartoma associated with arachnoid cysts. One case was initially documented on prenatal MR images. Because of the rarity of the association and resultant distortion in regional anatomy, the solid component of the mass may be overlooked. This would certainly be true when using lower-resolution diagnostic studies such as fetal MR imaging. The lesion could also be confused with a cystic tumor such as pilocytic astrocytoma. Thorough evaluation is required in patients with precocious puberty, gelastic seizures, and the presence of a suprasellar arachnoid cyst.

Abstract
BACKGROUND AND PURPOSE Reports of MR imaging in hypothalamic hamartomas associated with epilepsy are few, and the number of patients studied is small. We aimed to detail the relationship of hypothalamic hamartomas to surrounding structures, to determine the frequency and nature of associated abnormalities, and to gain insight into mechanisms of epileptogenesis. METHODS We systematically examined MR imaging studies of 72 patients with hypothalamic hamartoma and refractory epilepsy (patient age, 22 months to 31 years). A dedicated imaging protocol was used in 38 cases. Proton MR spectroscopy of the hypothalamic hamartoma was performed for 19 patients and compared with the metabolite profile of the thalamus in 10 normal children and the frontal lobe in 10 normal adults. RESULTS Compared with normal gray matter, hypothalamic hamartomas were hyperintense on T2-weighted images (93%), hypointense on T1-weighted images (74%), and had reduced N-acetylaspartate and increased myoinositol content shown by MR spectroscopy. Hypothalamic hamartomas always involved the mammillary region of the hypothalamus, with attachment to one or both mammillary bodies. Intrahypothalamic extension (noted in 97%) tended to displace the postcommissural fornix and hypothalamic gray matter anterolaterally, such that the hypothalamic hamartomas nestled between the fornix, the mammillary body, and the mammillothalamic tract. Larger hamartoma size was associated with central precocious puberty. Associated findings of questionable epileptic significance included anterior temporal white matter signal intensity abnormalities (16%) and arachnoid cysts (6%). Malformations of cortical development were observed in only two patients, and hippocampal sclerosis was not observed. CONCLUSIONS Hypothalamic hamartomas can be readily distinguished from normal hypothalamic gray and adjacent myelinated fiber tracts, best appreciated on thin T2-weighted images. MR imaging and spectroscopy suggest reduced neuronal density and relative gliosis compared with normal gray matter. Associated epileptogenic lesions are rare, supporting the view that the hypothalamic hamartoma alone is responsible for the typical clinical features of the syndrome. The intimate relationship to the mammillary body, fornix, and mammillothalamic tract suggests a role for these structures in epileptogenesis associated with hypothalamic hamartomas.

Abstract
The authors describe a unique case of a 2-year-old boy with a hypothalamic hamartoma secreting corticotropin-releasing hormone (CRH). The patient presented with a history of behavioral disturbances progressing over 12 months. His neurological status was intact. Magnetic resonance imaging demonstrated a 1.8 x 1.6 x 1.2-cm isointense, nonenhancing hypothalamic lesion. Endocrinological workup revealed elevated serum CRH and adrenocorticotropic hormone levels, nonsuppression with low-dose dexamethasone, and partial suppression with high-dose dexamethasone. He underwent tumor resection via a right frontotemporal craniotomy. Pathological examination of the tissue confirmed a hypothalamic hamartoma with CRH immunostaining. Postoperatively, his hormone levels normalized and his behavioral disturbances abated. The radiographic and clinical characteristics of hypothalamic hamartomas are reviewed and therapeutic considerations discussed.

Abstract
The authors report the case of a hypothalamic ganglioglioma with left-sided temporal lobe extension in an 8-year-old girl who presented with seizures. Other cases of ganglioglioma involving the hypothalamus have been reported in the literature; however, this site of origin is exceedingly rare and worthy of report. Treatment involved medial temporal lobectomy with the hypothalamic component of the tumor remaining untouched. The patient recovered postoperatively with no neurological deficits and was seizure free at 12 months. Neither radio- nor chemotherapy was recommended because of the tumor histology, location, and the patient's age. The authors recommend follow up and surgical treatment for possible tumor recurrence. The prognosis for hypothalamic ganglioglioma is unknown.
