Abstract
We report a case of pediatric glioma with uncommon imaging, morphological, and genetic features. A one-year-old boy incidentally presented with a tumor in the fourth ventricle. The tumor was completely resected surgically and investigated pathologically. The mostly circumscribed tumor had piloid features but primitive and anaplastic histology, such as increasing cellularity and mitosis. The Ki-67 staining index was 25% at the hotspot. KIAA1549::BRAF fusion and KIAA1549 partial deletions were detected by direct PCR, supported by Sanger sequencing. To the best of our knowledge, this is the first report of a glioma with both deletion of KIAA1549 p.P1771_P1899 and fusion of KIAA1549::BRAF. The tumor could not be classified using DNA methylome analysis. The present tumor fell into the category of pilocytic astrocytoma with histological features of anaplasia (aPA). Further studies are needed to establish pediatric aPA.

Abstract
The goal of treating patients with suprasellar meningioma is improving or preserving visual function while achieving long-term tumor control. We retrospectively examined patient and tumor characteristics and surgical and visual outcomes in 30 patients with a suprasellar meningioma who underwent resection via an endoscopic endonasal (15 patients), sub-frontal (8 patients), or anterior interhemispheric (7 patients) approach. Approach selection was based on the presence of optic canal invasion, vascular encasement, and tumor extension. Optic canal decompression and exploration were performed as key surgical procedures. Simpson grade 1 to 3 resection was achieved in 80% of cases. Among the 26 patients with pre-existing visual dysfunction, vision at discharge improved in 18 patients (69.2%), remained unchanged in six (23.1%), and deteriorated in two (7.7%). Further gradual visual recovery and/or maintenance of useful vision were also observed during follow-up. We propose an algorithm for selecting the appropriate surgical approach to a suprasellar meningioma based on preoperative radiologic tumor characteristics. The algorithm focuses on effective optic canal decompression and maximum safe resection, possibly contributing to favorable visual outcomes.

Abstract
PURPOSE Intratumoral thrombosis is a specific finding in glioblastomas and considered the origin of palisading necrosis. Its distribution and contribution to the glioblastoma pathophysiology and systemic thrombosis are obscure, although deep vein thrombosis is a common complication in glioblastoma cases. METHODS Clinicopathological and genetic analyses were performed on 97 glioblastoma tissue specimens to elucidate the role of thrombotic events and associated molecular abnormalities. RESULTS Morphologically, intratumoral thrombosis was observed more frequently in vessels composed of single-layered CD34-positive endothelium and/or αSMA-positive pericytes in the tumor periphery, compared to microvascular proliferation with multi-channeled and pericyte-proliferating vessels in the tumor center. Intratumoral thrombosis was significantly correlated with the female sex, high preoperative D-dimer levels, and epidermal growth factor receptor (EGFR) amplification. The presence of one or more thrombi in 20 high-power fields was a predictive marker of EGFR amplification, with a sensitivity of 81.5% and specificity of 52.6%. RNA sequencing demonstrated that the group with many thrombi had higher EGFR gene expression levels than the group with few thrombi. The tumor cells invading along the vessels in the tumor periphery were positive for wild-type EGFR but negative for EGFRvIII, whereas the cells around the microvascular proliferation (MVP) in the tumor center were positive for both wild-type EGFR and EGFRvIII. Intratumoral thrombosis is an independent poor prognostic factor. CONCLUSIONS Aberrant but exquisitely regulated EGFR can induce thrombosis in non-MVP vessels in the tumor invasion area and then promote palisading necrosis, followed by hypoxia, abnormal angiogenesis, and further tumor cell invasion.

Abstract
PURPOSE Pineal parenchymal tumors of intermediate differentiation (PPTIDs), which were recognized in the 2007 World Health Organization (WHO) classification, are rare, accounting for less than 1% of all central nervous system tumors. This rarity and novelty complicate the diagnosis and treatments of PPTID. We therefore aimed to evaluate the clinicopathological significance of this tumor. METHODS At 11 institutions participating in the Kyushu Neuro-Oncology Study Group, data for patients diagnosed with PPTID were collected. Central pathology review and KBTBD4 mutation analysis were applied to attain the diagnostically accurate cohort. RESULTS PPTID was officially diagnosed in 28 patients: 11 (39%) with WHO grade 2 and 17 (61%) with WHO grade 3 tumors. Median age was 49 years, and the male:female ratio was 1:2.1. Surgery was attempted in all 28 patients, and gross total resection (GTR) was achieved in 46% (13/28). Adjuvant radiotherapy and chemotherapy were administered to, respectively, 82% (23/28) and 46% (13/28). The 5-year progression-free survival (PFS) and overall survival rates were 64.9% and 70.4% respectively. Female sex (p = 0.018) and GTR (p < 0.01) were found to be independent prognostic factors for PFS and female sex (p = 0.019) was that for OS. Initial and second recurrences were most often leptomeningeal (67% and 100% respectively). 80% (20/25) of patients harbored a KBTBD4 mutation. CONCLUSIONS Female sex and GTR were independent prognostic factors in our patients with PPTID. Leptomeningeal recurrence was observed to be particularly characteristic of this tumor. The rate of KBTBD4 mutation observed in our cohort was acceptable and this could prove the accuracy of our PPTID cohort.

Abstract
Pharmacotherapy is frequently selected over surgical interventions for late elderly patients with trigeminal neuralgia (TN). However, medication may affect these patients' activities of daily living (ADL). Hence, we investigated the effect of the surgical treatment of TN on ADL in older patients. This study included 11 late elderly patients >75 years old and 26 nonlate elderly patients who underwent microvascular decompression (MVD) for TN at our hospital from June 2017 to August 2021. We evaluated pre- and postsurgical ADL using the Barthel Index (BI) score, side effects of antineuralgic drugs, the BNI pain intensity score, and perioperative medication. The BI score of late elderly patients significantly improved postoperatively, particularly in transfer (pre: 10.5; post: 13.2), mobility (pre: 10; post: 12.7), and feeding (pre: 5.9 points; post: 10 points). Additionally, antineuralgic drugs caused preoperative disturbances of transfer and mobility. Trends of a longer disease duration and frequent occurrence of side effects were observed in all patients in the elderly group, compared to only 9 out of 26 patients in the younger group (100% vs. 35%, p = 0.0002). In addition, drowsiness was observed more frequently in the late elderly group (73% vs. 23%, p = 0.0084). However, the change in scores indicating improvement after surgery was significantly greater in the late elderly group, although both pre- and postoperative scores were higher in the nonlate elderly group (11.4 ± 1.9 vs. 6.9 ± 0.7, p = 0.027). Surgical treatment can improve older patients' ADL because it relieves pain and facilitates discontinuation of antineuralgic drugs. Consequently, MVD can be positively recommended for older patients with TN if general anesthesia is acceptable.

Abstract
Abstract
Introduction
Chromosomal instability, the cell condition in which chromosome mis-segregation occur at a high frequency during cell division, has been considered to be involved in the molecular mechanisms that give rise to the complex genetic background of glioma. However, most of this phenomenon has been based on researches using cell line, and there have been few studies of chromosomal instability in clinical specimens of gliomas.
Methods
Primary cell culture was obtained from 11 glioma specimens (eight Glioblastoma (GBM), one Anaplastic PXA (aPXA), one Astrocytoma, and one Ependymoma), which was removed at our hospital, and chromosomes of up to five cells per case were analyzed by the SKY method. Chromosome instability was quantified by two parameters, one was AS (Aneuploidy score), which means the number of gain or loss of whole of the chromosome, and the other was SS: Structural abnormality score, which means the number of chromosome structural abnormality per cell. In addition, the phenotypes, which were characteristic of chromosomal instability were observed individually.
Results
Each quantitative value was as follows: GBM; AS:2.30±0.51 /SS:1.64±0.38, aPXA; AS :1.40±1.33 / SS:8.20±0.99, Astrocytoma and Ependymoma; AS:0.00 /SS:0.00, suggesting that chromosomal instability was associated with GBM and aPXA. Chromosome 7 amplification was most frequent in GBM (57%), and Mosaic loss of chromosome Y was also observed in 60% of males. Some characteristic karyotypes which suggest the phenomenon of Chromothripsis or Double minute were also observed. The karyotype concordance rate in the cases with p53 mutation was 60%, and that with p53 wild type was 100%, indicating that the p53 mutation increased the genotype heterogeneity in the same specimen.
Discussion
In clinical specimens of gliomas, aneuploidy and structural abnormalities were identified in GBM and aPXA, suggesting that chromosomal instability contributes to their cellular phenotype and malignancy.

Abstract
The efficacy of RMPV-A (rituximab, methotrexate, procarbazine, vincristine, and cytarabine) and whole brain irradiation for primary central nervous system lymphoma (PCNSL) have recently been reported. Our institution also introduced RMPV therapy in 2020 after an era of conventional HD-MTX to cytarabine and rituximab combination. In this report, we analyzed 60 PCNSL cases treated from 2013 to 2021.There were 32 female patients (53%) with a median age of 70 years (30-87). Five patients (8%) received radiotherapy alone as initial treatment, 30 (50%) received HD-MTX (including radiation), 17 (28%) received HD-MTX plus rituximab or cytarabine, and 9 (13%) received RMPV therapy. The response rate (CR, CRu, PR) in the HD-MTX group was 88%, and the complete response rate (CR, CRu) was 51%. In contrast, the RMPV arm had a response rate of 100% and a complete response rate of 6 patients (66.7%). 7 patients (14%) in the HD-MTX arm and 2 patients (22%) in the RMPV arm were unable to continue treatment due to adverse events. The treatment of PCNSL has undergone significant changes in recent years, with the availability of RMPV-A, thiotepa, and tirabrutinib, and it is now possible to construct treatment that avoids leukoencephalopathy caused by radiation therapy as much as possible, which had been a major problem of conventional therapy. However, because of the use of strong drugs, caution must be exercised when treating patients in poor general conditions, especially the elderly. However, the present analysis indicates that many elderly patients can be successfully treated with careful observation. In the future, it is essential to accumulate cases treated with RMPV therapy and tilabrutinib and conduct further data analysis to establish a new generation of treatment for PCNSL.

Abstract
BACKGROUND Primary central nervous system (CNS) germ cell tumors (GCTs) are rare neoplasms predominantly observed in the pediatric and young adult populations. A mixed GCT including immature teratoma exhibiting growing teratoma syndrome is presented. The pathogenesis of growing teratoma syndrome remains unclear, and its treatment strategy has not been established. GCTs are often located within the ventricles, causing hydrocephalus, which sometimes improves after removal of the tumor due to restoration of cerebrospinal fluid (CSF) flow. On the other hand, even if the flow route of CSF from the third ventricle to arachnoid granulations on the brain surface quadrigeminal cistern is restored after removal of the tumor, hydrocephalus may not improve. CASE PRESENTATION A case whose intractable hydrocephalus improved after penetrating the aqueductal membrane via endoscopy is described. An 11-year-old boy was treated for pineal intracranial growing teratoma syndrome (IGTS). The tumor grew rapidly in a short period, and hydrocephalus progressed despite endoscopic third ventriculostomy (ETV). Although the obstruction was removed by radiation, chemotherapy, and total tumor resection, the hydrocephalus did not improve. Endoscopic membrane perforation was performed because a membrane-like structure was seen at the entrance of the cerebral aqueduct on magnetic resonance imaging. The hydrocephalus improved immediately after the operation, and the patient's consciousness disturbance also improved significantly. CONCLUSION The purpose of this report is to update the current knowledge and standards of management for patients with growing teratoma syndrome, as well as to drive future translational and clinical studies by recognizing the unmet needs concerning hydrocephalus.

Although it has long been known as a hallmark of cancer cells, reduced cellular fitness upon induced ploidy alterations hinders the understanding of how aneuploidy relates to cancer development in the body. In this study, we employed the fluorescence in situ hybridization (FISH) analysis targeting centromeres to indicate ploidy changes, and quantitatively evaluated the ploidy statuses of gastric tumors derived from a total of 214 patients, ranging from early to advanced diseases. We found that cancer cells reveal a marked elevation of aneuploid population, increasingly in cases diagnosed in advanced stages. The expansion of aneuploid population is well associated with p53 deficiency, consistent with its essential role in genome maintenance. Comparisons among multiple locations within the tumor, or between the primary and metastatic tumors, indicated that cancer cells mostly remain their ploidy alterations throughout the primary tumors, but metastatic tumors may be consisted of cells with either increased or decreased levels of aneuploidy. We also found that a notable proportion of polyploid cells are often present already in chronic gastritis epithelia. These observations underscore that the chromosome-level variations are widespread in gastric cancers, shaping their genetic heterogeneity and malignant properties.

Abstract
Introduction: LYG is very rare tumor and composed of large EB-positive B cells and reactive T cells. In this study, we experienced a case of LYG with multiple intracranial, cutaneous, and pulmonary masses. We report the pathogenesis and pathophysiology of LYG, including a discussion of the literature. case: A 69-year-old female presented with a growing lump in her lower back that had been present for several years. Six months later, she was found to have multiple masses in her lungs and intracranial region and underwent surgical removal for diagnostic purposes. Intraoperative findings: The tumor was substantial, reddish to grayish-white in color, and the margins of the tumor were whitish and hard, with some areas that could not be detached. Pathological findings: There were no atypical lymphocytes, and a small number of EBER-positive cells were observed. IgVH PCR: IgVH PCR was performed on the skin lesions and intracranial lesions, and bands of different sizes were detected, suggesting that the IgVH clone was present in the polyclonal region. Finally, we diagnosed LYG grade 1. discussion: EB-associated lymphoproliferative disease can lead to polyclonal reactive growth or monoclonal neoplastic growth depending on the balance between morphology and host immunity. The results of IgVH PCR suggest that the skin lesions did not cause multiple metastases, but rather that the enlargement of the skin lesions triggered intracranial and pulmonary lesions in an allo-centric manner. The results of IgVH PCR suggested that the skin lesions did not cause multiple metastases, but rather that the skin lesions grew to cause intracranial and pulmonary involvement in an other-centric manner.

Abstract
Introduction: Pathological features of glioblastoma include intravascular thrombosis, suggesting that the thrombus formation in tumor microenvironment contributes to progression of gliomas. Meanwhile, glioblastoma has been known to be high risk malignant tumor for venous thromboembolism, however, it remains unclear how the coagulation-fibrinolysis system is disrupted, which essentially grow within the cranium in a localized manner, and how the disruption contributes to the malignant transformation. Methods: Total 64 patients with glioblastoma between January 2014 and April 2021 who underwent a D-dimer test before the therapeutic intervention were divided into two groups: the high D-dimer group (D-dimer level >3.0μg/ml) and the low D-dimer group (D-dimer level <3.0μg/ml). We compared the two groups in the maximum gadolinium-enhanced MRI lesions, MIB-1 index, and gene abnormalities (IDH mutation, TERT promoter mutation, and MGMT promotor methylation). The progression-free survival (PFS) and overall survival were analyzed using the Kaplan-Meier method. Furthermore, in 23 patients who underwent a D-dimer test at recurrence, the time to death after recurrence was analyzed. Results: The PFS in high D-dimer group was significantly shorter than that in the low D-dimer group (log-rank p = 0.0075). The D-dimer increase at the time of recurrence significantly correlated with the decrease in post-recurrence survival duration (log-rank p = 0.0226). Moreover, the gadolinium-enhanced lesions in the high D-dimer group were significantly larger. Conclusion: The Pre-intervention D-dimer levels and PFS suggest that glioblastoma-induced systemic enhancement of the coagulation-fibrinolysis system plays a role in the malignant transformation. The D-dimer increase during the treatment was found to be a predictor of poor prognosis after recurrence. Furthermore, the MRI findings revealed a correlation between the D-dimer increase and the size of intratumoral necrosis. Meanwhile, no correlation with the MIB-1 index was found, suggesting that the mechanism of malignant transformation by hypercoagulation differ from enhanced cell proliferation.

Abstract
Background Cerebrospinal fluid (CSF) cytology and spinal MR imaging are routinely performed for staging before treatment of intracranial germinoma. However, the interpretation of the results of CSF cytology poses 2 unresolved clinical questions: (1) Does positive CSF cytology correlate with the presence of spinal lesion before treatment? and (2) Is craniospinal irradiation (CSI) necessary for patients with positive CSF cytology in the absence of spinal lesion? Methods Multicenter retrospective analyses were performed based on a questionnaire on clinical features, spinal MR imaging finding, results of CSF cytology, treatments, and outcomes which was sent to 86 neurosurgical and 35 pediatrics departments in Japan. Pretreatment frequencies of spinal lesion on MR imaging were compared between the patients with positive and negative cytology. Progression-free survival (PFS) rates were compared between patients with positive CSF cytology without spinal lesion on MR imaging treated with CSI and with whole brain or whole ventricular irradiation (non-CSI). Results A total of 92 germinoma patients from 45 institutes were evaluated by both CSF cytology and spinal MR images, but 26 patients were excluded because of tumor markers, the timing of CSF sampling or incomplete estimation of spinal lesion. Of the remaining 66 germinoma patients, spinal lesions were equally identified in patients with negative CSF cytology and positive cytology (4.9% and 8.0%, respectively). Eleven patients treated with non-CSI had excellent PFS comparable to 11 patients treated with CSI. Conclusion CSI is unnecessary for germinoma patients with positive CSF cytology without spinal lesions on MR imaging.

Abstract
This study aimed to examine the beneficial effects of a novel prophylactic barbiturate therapy, step-down infusion of barbiturates, using thiamylal with normothermia (NOR+sdB), on the poor outcome in the patients with severe traumatic brain injuries (sTBI), in comparison with mild hypothermia (MD-HYPO). From January 2000 to March 2019, 4133 patients with TBI were admitted to our hospital. The inclusion criteria were: a Glasgow coma scale (GCS) score of ≤8 on admission, age between 20 and 80 years, intracranial hematoma requiring surgical evacuation of the hematoma with craniotomy and/or external decompression, and patients who underwent management of body temperature and assessed their outcome at 6-12 months. Finally, 43 patients were included in the MD-HYPO (n = 29) and NOR+sdB (n = 14) groups. sdB was initiated intraoperatively or immediately after the surgical treatment. There were no significant differences in patient characteristics, including age, sex, past medical history, GCS on admission, type of intracranial hematoma, and length of hospitalization between the two groups. Although NOR+sdB could not improve the patient's poor outcome either at discharge from the intensive care unit (ICU) or at 6-12 months after admission, the treatment inhibited composite death at discharge from the ICU. The mean value of the maximum intracranial pressure (ICP) in the NOR+sdB group was <20 mmHg throughout the first 120 h. NOR+sdB prevented composite death in the ICU in patients with sTBI, and we may obtain novel insights into the beneficial role of prophylactic barbiturate therapy from suppression of the elevated ICP during the first 120 h.

Abstract
Intracranial pressure (ICP) has to be maintained quite constant, because increased ICP caused by cerebrovascular disease and head trauma is fatal. Although controlling ICP is clinically critical, only few therapeutic methods are currently available. Barbiturates, a group of sedative-hypnotic drugs, are recognized as secondary treatment for controlling ICP. We proposed a novel "step-down infusion" method, administrating barbiturate (thiamylal) after different time point from the start of treatment under normothermia, at doses of 3.0 (0-24 h), 2.0 (24-48 h), 1.5 (48-72 h), and 1.0 mg/kg/h (72-96 h), and evaluated its safety and effectiveness in clinical. In 22 patients with severe traumatic brain injury or severe cerebrovascular disease (Glasgow coma scale ≤8), thiamylal concentrations and ICP were monitored. The step-down infusion method under normothermia maintained stable thiamylal concentrations (<26.1 µg/ml) without any abnormal accumulation/elevation, and could successfully keep ICP <20 mmHg (targeted management value: ICP <20 mmHg) in all patients. Moreover the mean value of cerebral perfusion pressure (CPP) was also maintained over 65 mmHg during all time course (targeted management value: CPP >65 mmHg), and no threatening changes in serum potassium or any hemodynamic instability were observed. Our novel "step-down infusion" method under normothermia enabled to maintain stable, safe thiamylal concentrations to ensure both ICP reduction and CPP maintenance without any serious side effects, may provide a novel and clinically effective treatment option for patients with increased ICP.

Abstract
BACKGROUND The Delphi consensus statements on the management of germ cell tumors (GCTs) failed to reach agreements on the statement that the cases with (i) pineal and neurohypophyseal bifocal lesion, (ii) with diabetes insipidus, and (iii) with negative tumor markers can be diagnosed as germinoma without histological verification. To answer this, multicenter retrospective analysis was performed. METHODS A questionnaire on clinical findings, histological diagnosis, and details of surgical procedures was sent to 86 neurosurgical and 35 pediatrics departments in Japan. RESULTS Fifty-one institutes reported 132 cases that fulfilled the 3 criteria. Tissue sampling was performed in 91 cases from pineal (n = 44), neurohypophyseal (n = 32), both (n = 6), and distant (n = 9) lesions. Histological diagnosis was established in 89 cases: pure germinoma or germinoma with syncytiotrophoblastic giant cells in 82 (92.1%) cases, germinoma and mature teratoma in 2 cases, and granulomatous inflammation in 2 cases. Histological diagnosis was not established in 2 cases. Although no tumors other than GCTs were identified, 3 (3.4%) patients had non-germinomatous GCTs (NGGCTs). None of the patients developed permanent complications after endoscopic or stereotactic biopsy. Thirty-nine patients underwent simultaneous procedure for acute hydrocephalus without permanent complications, and hydrocephalus was controlled in 94.9% of them. CONCLUSION All patients who fulfilled the 3 criteria had GCTs or granulomatous inflammation, but not other types of tumors. However, no fewer than 3.4% of the patients had NGGCTs. Considering the safety and the effects of simultaneous procedures for acute hydrocephalus, biopsy was recommended in such patients.

Abstract
OBJECTIVE Endoscopic third ventriculostomy (ETV) has now become an accepted mode of hydrocephalus treatment. However, the long-term effects of ETV for myelomeningocele-related hydrocephalus (MMC-rH) after shunt malfunction remains unclear. We aimed to assess the long-term outcome and the factors associated with the success of ETV for MMC-rH after shunt malfunction. METHODS We performed a retrospective analysis of data collected between 2001 and 2018 from 8 patients with MMC-rH after shunt malfunction, who underwent ETV at the Kurume University Hospital and were followed up for at least 5 years. We extracted data regarding age, sex, clinical symptoms, radiological imaging, intraoperative findings, and outcomes. RESULTS The overall success rate was 62.5% and their ETV success score is 67.5. The most frequent clinical symptom was intracranial hypertension symptoms (100 %), followed by Chiari type II symptoms (87.5 %). In preoperative MRI scans, we observed aqueduct stenosis in 6 cases, Chiari type II malformations in 7 cases, four patients had a narrow prepontine cistern, five patients had an absent septum pellucidum, and three presented with stenosis of the foramen of Monro. All cases in the failure group had the above 5 symptoms. Based on intraoperative findings, a thick third ventricle floor was found in 5 patients. Two patients had a thin hypothalamic adhesion in the third ventricle floor. They had no major complications. CONCLUSION ETV for MMC-rH after shunt malfunction is an effective treatment option. However, we recommend that a neurosurgeon with extensive experience in neuroendoscopy perform ETV because MMC patients more often had intraventricular malformations than those with other hydrocephalus diseases.

Abstract
Chromosomal instability (CIN) is a pathological condition where cells continuously mis-segregate chromosomes, producing aneuploid cells. CIN has been recognized as a hallmark of cancer, and its correlation with biological malignancy has been pointed out. Glioma cell line often reveals karyotype aberrations, and a variety of ploidy in the tumor tissue. However, several studies have indicated that aneuploidy is disadvantageous for proliferation or tumorigenesis, and these paradox prompt us to address the role of aneuploid cells in tumor specimens. Here, we adopted mouse glioma stem cell lineages and found that aneuploid population is increased in glioma stem cells in vitro. We also examined Aurora B at centromeres which is crucial for failsafe chromosome segregation and found its reduced activity in glioma stem cells, suggesting that insufficient Aurora B activity plays a causative role in CIN in glioma stem cells. Next, to investigate the tumorigenicity of aneuploid cells, we sorted the glioma stem cells depending on the karyotype pattern, and allografted into mouse brain. We found that the growth rate of diploid glioma stem cells was higher than others in vitro, and the probability of survival after allogeneic transplant was significantly lower in diploid groups. We will discuss the role of ploidy in glioma cells populations.

Abstract
OBJECTIVE The optimal treatment method for persistent Blake's pouch cyst (BPC) remains unclear owing to its low prevalence. We aimed to characterize a patient population with adult BPC and to identify the risk factors associated with endoscopic third ventriculostomy (ETV) for BPC. This study reports the largest number of BPC cases in adults and is the first report to reveal the long-term outcomes of ETV in such patients. METHODS We performed a retrospective analysis of data collected from seven adult patients with BPC between 2005 and 2019. They underwent ETV at the Kurume University Hospital and were followed up for five years or more. We extracted data regarding patient age, sex, clinical symptoms, radiological imaging, intraoperative findings and outcomes. RESULTS The ages of the patients ranged between 30 and 60 years (45 ± 12 years). The mean postoperative follow-up time was 92.1 ± 13.5 months. The overall success rate was 71.4%. The most frequent symptom was headache (86%), followed by mild cognitive impairment (71%). The average cerebrospinal fluid pressure was slightly elevated (18.4 ± 1.4 cmH2O). A decrease in ventricular size (Evans' index) detected early after ETV was associated with satisfactory clinical outcomes (p = 0.02). The incidence of prepontine scarring was observed in all cases of the ETV failure group. A significant risk factor for ETV was the to-and-fro movements of the third ventricle floor after ETV (p = 0.048). CONCLUSIONS ETV could be a safe and effective treatment option for adult patients with BPC. It is important that prepontine scarring and the to-and-fro movements of the third ventricle after ETV should be confirmed carefully when performing ETV on adult patients with BPC.

Abstract
Background: In some cases of acute brainstem infarction (BI), standard axial diffusion-weighted imaging (DWI) does not show a lesion, leading to false-negative (FN) diagnoses. It is important to recognize acute BI accurately and promptly to initiate therapy as soon as possible. Methods: Of the 171 patients with acute cerebral infarctions in our institution who were examined, 16 were diagnosed with true-positive BI (TP-BI) and six with FN-BI. We evaluated the effectiveness of sagittal DWI in accurately diagnosing acute BI and sought to find the cause of its effectiveness by the anatomical characterization of FN-BIs. Results: Considering the direction of the brainstem perforating arteries, we supposed that sagittal DWI might more effectively detect BIs than axial DWI. We found that sagittal DWI detected all FN-BIs more clearly than axial DWI. The mean time between the onset of symptoms and initial DWI was significantly longer in the TP group (17.6 ± 5.5 h) than in the FN group (5.0 ± 1.2 h; P < 0.0001). The lesion volumes were much smaller in FN-BIs (259 ± 82 mm3) than in TP-BIs (2779 ± 767 mm3; P = 0.0007). FN-BIs had a significant inverse correlation with the ventrodorsal length of infarcts (FN 3.5 ± 1.1 mm, TP 11.4 ± 3.6 mm; P < 0.0004) and no correlation with other size parameters such as rostrocaudal thickness and lateral width. Conclusion: Anatomical characterization clearly confirmed that the addition of sagittal DWI to the initial axial DWI in suspected cases of BI ensures its accurate diagnosis and improves the patient’s prognosis.

Abstract
Background Cases involving delayed development of intracranial aneurysms related to gamma knife surgery (GKS) have been recently reported. Here, we present a rare case of GKS-induced aneurysm rupture after intravenous injection of tissue plasminogen activator (t-PA) for occlusion of the middle cerebral artery (MCA). To the best of our knowledge, this is the first case in which t-PA-induced rupture of a GKS-related unruptured aneurysm. Case Description A 56-year-old woman underwent GKS for left trigeminal neuralgia. Eighteen years later, she suddenly experienced MCA occlusion with consciousness disturbance and right hemiparesis. She received an intravenous injection of t-PA and then was transferred to our hospital. We confirmed residual thrombus, and she underwent mechanical thrombectomy successfully. A postthrombectomy brain computed tomography scan revealed subarachnoid hemorrhage with a hematoma in the left cerebellar hemisphere. Cerebral angiography revealed a small irregular-shaped aneurysm at the branching site of the left circumflex branch at the distal position of the anterior inferior cerebellar artery, which was not detected on initial imaging. Coil embolization was performed. One month after the ischemic attack, she was transferred to a rehabilitation hospital, with a modified Rankin Scale score of 5. Conclusions The tendency to rupture is greater for GKS-induced aneurysms than for intrinsic unruptured aneurysms, according to previous reports. When performing acute treatment for cerebral infarction in patients with a history of GKS, the presence of aneurysms should be evaluated and we should keep in mind that GKS aneurysms are very small and tend to rupture.

Abstract
BACKGROUND Several possible mechanisms exist for the spread of a primary tumor to the leptomeninges in leptomeningeal carcinomatosis. This report describes a case caused by direct bleeding in the subarachnoid space from a neoplastic cerebral aneurysm rupture. CASE DESCRIPTION A 48-year-old Japanese woman, who was diagnosed with breast carcinoma (pT3 pN2 M0) at the age of 45 years and underwent mastectomy and chemotherapy, was admitted in a coma following a sudden-onset severe headache. Computed tomography revealed diffuse hemorrhage in the subarachnoid space, and angiography revealed an aneurysm at the distal middle cerebral artery. Superficial temporal artery-middle cerebral artery bypass, aneurysmal trapping, and aneurysm resection were performed within 24 hours of admission. Staining for AE1/AE3 revealed accumulation of atypical cells with a high nuclear-cytoplasmic ratio in the aneurysmal wall. After showing initial improvement, she developed disturbed consciousness due to complicated ventricular enlargement on day 45. Although the cerebrospinal fluid in the acute phase had no atypical cells, subsequent testing revealed atypical cells, which supported a diagnosis of leptomeningeal carcinomatosis due to breast cancer dissemination. The patient died on day 78 after receiving standard endocrine therapy and radiation therapy. CONCLUSIONS Tumor cells reach the leptomeninges via hematogenous spread or direct extension from preexisting lesions and can undergo neuraxis dissemination via the cerebrospinal fluid. Subarachnoid hemorrhage and leptomeningeal carcinomatosis are both devastating conditions with extremely poor prognoses. This patient experienced delayed disturbed consciousness leptomeningeal carcinomatosis with decreased performance status, which made it difficult to justify aggressive treatment on the basis of her poor prognosis.

Abstract
Ischemia-reperfusion injuries produce reactive oxygen species that promote the peroxide lipid oxidation process resulting in the production of an endogenic lipid peroxide, 4-hydroxy-trans-2-nonenal (4-HNE), a highly cytotoxic aldehyde that induces cell death. We synthesized a novel 4-HNE scavenger - a carnosine-hydrazide derivative, l-carnosine hydrazide (CNN) - and examined its neuroprotective effect in a model of transient ischemia. PC-12 cells were pre-incubated with various doses (0-50 mmol/L) of CNN for 30 min, followed by incubation with 4-HNE (250 μM). An MTT assay was performed 24 h later to examine cell survival. Transient ischemia was induced by bilateral common carotid artery occlusion (BCCO) in the Mongolian gerbil. Animals were assigned to sham-operated (n = 6), placebo-treated (n = 12), CNN pre-treated (20 mg/kg; n = 12), CNN post-treated (100 mg/kg; n = 11), and histidyl hydrazide (a previously known 4-HNE scavenger) post-treated (100 mg/kg; n = 7) groups. Heat shock protein 70 immunoreactivity in the hippocampal CA1 region was evaluated 24 h later, while delayed neuronal death using 4-HNE staining was evaluated 7 days later. Pre-incubation with 30 mmol/L CNN completely inhibited 4-HNE-induced cell toxicity. CNN prevented delayed neuronal death by >60% in the pre-treated group (p < 0.001) and by >40% in the post-treated group (p < 0.01). Histidyl hydrazide post-treatment elicited no protective effect. CNN pre-treatment resulted in high heat shock protein 70 and low 4-HNE immunoreactivity in CA1 pyramidal neurons. Higher 4-HNE immunoreactivity was also found in the placebo-treated animals than in the CNN pre-treated animals. Our novel compound, CNN, elicited highly effective 4-HNE scavenging activity in vitro. Furthermore, CNN administration both pre- and post-BCCO remarkably reduced delayed neuronal death in the hippocampal CA1 region via its induction of heat shock protein 70 and scavenging of 4-HNE.

Abstract
Background Some patients with moyamoya disease (MMD) show broad infarction with moderate internal carotid artery (ICA) stenosis, whereas others with complete ICA occlusion show no infarction. This suggests that other factors contribute to the occurrence of infarction. Contributing factors predictive of cerebral infarcts must be identified for the prevention of infarction and the consequent neurological deficits. Methods We examined data from 93 patients with confirmed MMD for the presence of infarction (n = 72), transient ischemic attack (TIA, n = 41), asymptomatic presentation (n = 51), or hemorrhage (n = 22) in 186 bilateral cerebral hemispheres. We analyzed the relationship between the occurrence of infarction and several clinical factors, such as steno-occlusive status or the site of the ICA and posterior cerebral artery (PCA). Results The incidence of PCA steno-occlusive lesions was significantly higher in infarcted (77.8%) than in non-infarcted hemispheres (TIA, 14.6%; asymptomatic, 9.8%; hemorrhagic 9.1%; P < 0.01). The steno-occlusive site of ICA was also a significant factor (P < 0.05). There was no significant correlation between the occurrence of infarction and the steno-occlusive status of the ICA or grade of the moyamoya vessels. Multivariate statistical analysis demonstrated that the PCA steno-occlusive changes were an important contributing factor for infarction (P < 0.0001). Conclusions This is the multivariate statistical analysis study identifying PCA steno-occlusive lesions as the most important independent factor that is predictive to cerebral infarction in moyamoya patients. The prediction and inhibition of PCA steno-occlusive changes may help to prevent cerebral infarction.

Abstract
Background: Malignant transformation of craniopharyngiomas is quite rare, and the etiology of transformation remains unclear. The prognosis of malignantly transformed craniopharyngiomas is very poor. Case Description: A 36-year-old male had five craniotomies, five transsphenoidal surgeries, and two radiation treatments until 31 years of age after diagnosis of craniopharyngioma at 12 years of age. All serial pathological findings indicated adamantinomatous craniopharyngioma including those of a surgery performed for tumor regrowth at 31 years of age. However, when the tumor recurred approximately 5 years later, the pathological findings showed squamous metaplasia. The patient received CyberKnife surgery, but the tumor rapidly regrew within 4 months. The tumor was resected with the cavernous sinus via a dual approach: Transcranial and transsphenoidal surgery with an extracranial-intracranial bypass using the radial artery. Pathologic examination of a surgical specimen showed that it consisted primarily of squamous cells; the lamina propria was collapsed, and the tumor cells had enlarged nuclei and clarification of the nucleolus. The tumor was ultimately diagnosed as malignant transformation of craniopharyngioma. After surgery, he received combination chemotherapy (docetaxel, cisplatin, and fluorouracil). The tumor has been well controlled for more than 12 months. Conclusion: Serial pathological changes of the craniopharyngioma and a review of the 20 cases reported in the literature suggest that radiation of the squamous epithelial cell component of the craniopharyngioma led to malignant transformation via squamous metaplasia. We recommend aggressive surgical removal of craniopharyngiomas and avoidance of radiotherapy if possible.
