Abstract
OBJECTIVE Exceedingly refractory, pediatric anaplastic ependymoma in many cases requires multisurgical removal. The high risk of poor wound healing and CSF leakage especially at the posterior fossa make this tumor difficult to treat. CASE A 9-year-old girl has had 4th ventricular anaplastic ependymoma since the age of 3. She experienced tumor removal 8 times including 4 posterior fossa craniotomies because tumors were disseminated not only to the posterior fossa but also to the cerebral hemispheres. She also underwent a dermal graft using a free flap. She experienced CSF leaks and meningitis frequently because the wound healing was poor. We performed a dermal flap closure using a pedicle trapezius muscle flap with a plastic surgeon when we performed the 5th tumor removal. RESULT We achieved complete wound closure in spite of broad deficiencies in subcutaneous and epidermal tissues. After that, recurrences of posterior fossa tumors presented within a short term, and tumor removal via an incision of a pedicle trapezius muscle flap was performed without recurrence of CSF leaks and meningitis. DISCUSSION AND CONCLUSION For the first time, we are able to report on the efficacy of using the pedicle trapezius muscle flap for multisurgical removal of pediatric posterior fossa anaplastic ependymoma. The muscle flap was found to be effective because of the multiple surgeries expected, and the pedicle trapezius muscle flap was found to be resilient to multiple surgical procedures. Although advantageous, the dorsal scapular artery which is required for flap creation is actually difficult to harvest. Compared to a flee flap, the pedicle trapezius muscle flap maintains vascular supply. Furthermore, this technique has the possibility of being applied to defective dura mater closure that cannot be watertight due to multiple surgeries. However, it is very important to inform the patient's family not only about the improved efficacy of surgery, but also to raise awareness on consequential cosmetic issues.

Abstract
Hypothalamic hamartoma is a less common condition characterized by the several types of epileptic seizures including the gelastic type. It is reported that gelastic seizures are resistant to medical treatment with anticonvulsants, while stereotactic thermocoagulation or Gamma Knife radiosurgery are effective for seizure control. Here, we report an individual case where direct surgical resection disconnecting hypothalamic hamartoma from mammillothalamic tract resulted in complete disappearance of gelastic seizures without deterioration of cognitive function. A 6-year-old boy developed gelastic seizures at the age of 2 and suffered from precocious puberty. Anticonvulsants including carbamazepine and zonisamide failed to control seizures. The patient underwent direct division of the mammillothalmic tract by removal of hypothalamic hamartoma partially via anterior interhemispheric approach. It was observed that gelastic seizures disappeared completely after the surgical treatment without any endocrine and cognitive dysfunction for a follow-up period of 14 years. The mammillothalamic tract which connects anterior nucleus of thalamus and mammillary bodies plays a key role in gelastic seizures related to hypothalamic hamartoma. In this case, we disconnected the hamartoma specifically from the mammillary bodies and not from the rest of hypothalamus. Effectively, it enabled permanent control of seizures. This result shows that fibers connecting other hypothalamic structures and the dorsomedial nucleus of thalamus are not involved in gelastic seizure propagation from the hypothalamic hamartoma. When surgical treatment of hypothalamic hamartomas is performed it has high morbidity associated with hypothalamic disorders. Therefore, disconnection between hypothalamic hamartoma and mammillary bodies presents a possibility of reducing hypothalamic damage. Surgical disconnection between hamartoma and mammillothalamic tract carries minimal hypothalamic injury risk and our results suggest that it has the potential of seizure control for intractable gelastic seizures with less complications.

Abstract
OBJECTIVE Some aneurysmal subarachnoid hemorrhage (SAH) patients are delayed in their presentation. This can cause a washout of the subarachnoid hematoma and a potential misdiagnosis. As a result, they may suffer rerupture of the aneurysm and preventable deterioration. We investigated the factors that influence delayed SAH presentation. METHODS Aneurysmal SAH patients treated at 9 stroke centers from 2002 to 2020 were included. Age, gender, pre-SAH modified Rankin scale, World Federation of Neurological Surgeons grade, Fisher group, day of presentation, aneurysm treatment method, past history of cerebral stroke, comorbidity of hypertension and/or diabetes mellitus, and modified Rankin scaleat discharge were assessed retrospectively. We formed 2 groups based on the day of presentation after the onset of SAH: day 0-3 (early) and other (delayed). Logistic regression analyses detected the factors that influenced the day of presentation and outcome for SAH. A P- value <0.05 was considered significant. RESULTS Delayed presentation comprised 282 cases (6.3%) of 4507 included cases. Logistic regression analyses showed that patients in an urban area, of male gender, low WFNS grade and low Fisher group correlated significantly with a delayed presentation. But delayed presentation did not influence outcome at discharge. CONCLUSIONS Area of residency and gender correlated with delayed presentation after SAH in Japan. Urbanization, male gender, and mild SAH lead patients to delay presentation. The factors underlying these tendencies will be analyzed in a future prospective study.

Abstract
OBJECTIVE Although the short- to medium-term efficacy of Gamma Knife therapy for drug-resistant essential trigeminal neuralgia has been reported, long-term evaluations are limited. We evaluated patient data obtained at least 10 years post-treatment and examined the significance of this treatment using new end points. METHODS Among 249 consecutive patients with essential trigeminal neuralgia who were treated with Gamma Knife radiosurgery (retrogasserian target/4-mm single isocenter/90 Gy at 100%) at our institution between January 2003 and October 2011, 103 patients who were followed up for at least 10 years (mean, 174 [120-219] months) after treatment and whose data were amenable to accurate evaluation, were included in this retrospective study. Herein, we used the Barrow Neurological Institute (BNI) pain intensity scale as a clinical evaluation method for pain and the BNI numbness scale to evaluate complications (namely facial dysesthesia). RESULTS The initial and final follow-up pain attack cessation (BNI pain intensity score I-IIIa) rate was 82.5% (85 of 103) and 58.2% (60 of 103), respectively. Furthermore, sensory impairment (BNI numbness score ≥ II) at the last follow-up was observed in 24.3% (25 of 103) of the cases, while very bothersome status (BNI numbness score IV) was observed in 2.9% of the cases. CONCLUSIONS Gamma Knife radiosurgery for essential trigeminal neuralgia showed good therapeutic effects during long-term follow-up. Serious complications of significant concern in the short- to mid-term follow-up, resolved spontaneously. Therefore, the indications for treatment should be expanded to include patients who strongly desire Gamma Knife therapy.

Abstract
PURPOSE Surgical site infections (SSIs) after neurosurgery are common in daily practice. Although numerous reports have described SSIs in neurosurgery, reports specific to gliomas are limited. This study aimed to investigate the relationship between SSIs and glioma treatment characteristics, such as reoperations, radiation therapy, and chemotherapy. METHODS We examined 1012 consecutive patients who underwent craniotomy for glioma between November 2013 and March 2022. SSIs were defined as infections requiring reoperation during the observation period, regardless of their location. We retrospectively analyzed SSIs and patient factors. RESULTS During the observation period, SSIs occurred in 3.1% (31/1012). In the univariate analysis, three or more surgeries (P = 0.007) and radiation therapy (P = 0.03) were associated with SSIs, whereas intraoperative magnetic resonance imaging (MRI) was not significantly associated (P = 0.35). Three or more surgeries and radiation therapy were significantly correlated with each other (P < .0001); therefore, they were analyzed separately in the multivariate analysis. Three or more surgeries were an independent factor triggering SSIs (P = 0.02); in contrast, radiation therapy was not an independent factor for SSIs (P = 0.07). Several SSIs localized in the skin occurred more than 1 year after surgery. CONCLUSIONS Undergoing three or more surgeries for glioma is an independent risk factor for SSIs. Glioma SSIs can occur long after surgery. These results are considered characteristic of gliomas. We recommend careful long-term observation of patients at a high risk of SSIs.

Abstract
BACKGROUND Symptomatic cerebral vasospasm after subarachnoid hemorrhage (SAH) is a significant cause of delayed cerebral ischemia that leads to poor outcomes. Selective intra-arterial administration of fasudil hydrochloride (IAF) has been adopted for its vasodilatory effect on spasm arteries to prevent delayed cerebral ischemia. However, its effect on clinical outcomes and predictive factors for good recovery are not fully understood. This study aimed to investigate the outcomes of selective IAF and identify predictive factors for good outcomes in patients with cerebral vasospasm after SAH. METHODS A retrospective study of 36 patients with cerebral vasospasm following SAH who underwent selective IAF at our institution between January 2014 and May 2022 was conducted. We evaluated the improvements in neurological findings before and after selective IAF. Statistical analyses were performed to determine factors associated with good outcomes. RESULTS Selective IAF improved the neurological findings in 26 patients (72.2%). Pre-therapeutic absence of cerebral infarction in more than 1/3 of the spasm artery perfusion area was significantly associated with an improvement in neurological findings (p < 0.0001). Furthermore, there was a tendency for a good outcome when the age was younger (p = 0.093), and the spasm was limited to peripheral vessels (p = 0.065). CONCLUSION Our study indicates that selective IAF has a promising effect in improving symptomatic vasospasm, except when a large cerebral infarction exists in the spasm artery perfusion area. Early consideration of selective IAF could be recommended once patients experience symptomatic cerebral vasospasm after SAH.

Abstract
SGCE myoclonus-dystonia is a monogenic form of dystonia with an autosomal dominant mode of inheritance that co-occurs with a myoclonic jerk. In this study, we present 12 Japanese patients from nine families with this disease. Targeted next-generation sequencing covering major causative genes for monogenic dystonias identified nine distinct SGCE mutations from each of the families: three nonsense, two frameshift, two missense, one in-frame 15 bp deletion, and one splice donor site mutations, of which four were previously unreported. One missense mutation (c.662G>T, p.Gly221Val) was located at the 3' end of exon 5 (NM_001099400), which was predicted to cause aberrant splicing according to in silico predictions. Minigene assays performed together with the c.825+1G>C mutation demonstrated complete skipping of exon 5 and 6, respectively, in their transcripts. The other missense (c.1345A>G, p.Met449Val) and 15 bp deletion (c.168_182del, p.Phe58_Leu62del) mutations showed a significant reduction in cell membrane expression via HiBiT bioluminescence assay. Therefore, we concluded that all the detected mutations were disease-causing. Unlike the other detected mutations, p.Met449Val affects only isoform 3 (NP_001092870 encoded by NM_001099400) among the variously known isoforms of SGCE. This isoform is brain-specific and is mostly expressed in the cerebellum, which supports recent studies showing that cerebellar dysfunction is a key element in the pathophysiology of SGCE myoclonus-dystonia.

Abstract
PURPOSE To retrospectively evaluate preoperative clinical factors for their ability to preoperatively differentiate malignancy grades in patients with incipient supratentorial grade II/III diffuse gliomas. METHODS This retrospective study included 206 adult patients with incipient supratentorial grade II/III diffuse gliomas according to the 2016 World Health Organization classification of tumors of the central nervous system. The cohort included 136 men and 70 women, with a median age of 41 years. Preoperative factors included age, sex, presence of calcifications on computed tomography scans, and preoperative tumor volume measured using preoperative magnetic resonance imaging. RESULTS In patients with oligodendrogliomas (IDH-mutant and 1p/19q-codeleted), calcifications were significantly more frequent (p = 0.0034) and tumor volume was significantly larger (p < 0.001) in patients with grade III tumors than in those with grade II tumors. Moreover, in patients with IDH-mutant astrocytomas, preoperative tumor volume was significantly larger (p = 0.0042) in patients with grade III tumors than in those with grade II tumors. In contrast, none of the evaluated preoperative clinical factors were significantly different between the patients with grade II and III IDH-wildtype astrocytomas. CONCLUSION In adult patients with suspicison incipient supratentorial grade II/III diffuse gliomas, presence of calcifications and larger preoperative tumor volume might be used as preoperative indices to differentiate between malignancy grades II and III in oligodendrogliomas (IDH-mutant and 1p/19q-codeleted) and larger preoperative tumor volume might have similar utility in IDH-mutant astrocytomas.

Abstract
We describe the case of a 17-year-old woman diagnosed with complex regional pain syndrome (CRPS) at a pain clinic after the second dose of the COVID-19 vaccine. She was referred to our department for surgical treatment of movement disorder seven months after the second inoculation. Baclofen (50 µg), administered intrathecally, improved the involuntary movements of her right hand. After administration of zolpidem (5 mg), involuntary movements of the right index finger almost disappeared. However, neither zolpidem nor intrathecal baclofen improved the limited range of motion of the first joint of the left-hand finger. Despite various reports on CRPS development after vaccination, only one case post COVID-19 vaccination has been reported. Therefore, healthcare providers should keep in mind that CRPS can appear after the COVID-19 vaccination.

Abstract
Pituicytoma is a rare neoplasm, arising in the posterior pituitary or in the hypophyseal stalk, and its cytological findings have not yet been well-described. We have experienced a case of pituicytoma, which was difficult to diagnose intraoperatively, because of its cellular pleomorphism. A tumor measuring 18 mm in maximum diameter was found at the sella turcica in a Japanese woman in her forties. Both intraoperative crush cytology and histology of the resected tumor showed pleomorphic spindle or round cells, including multinucleated cells. Tumor cells were positive for TTF-1, S-100 protein, and vimentin, partially positive for glial fibrillary acidic protein and epithelial membrane antigen, and negative for synaptophysin, hormones of the anterior pituitary gland, CD34, Olig2, PAX8, and napsin A. Ki-67 labeling index was 2.0%. Tumors included in the differential diagnosis in general are pituitary adenoma, craniopharyngioma, germinoma, and metastatic tumor on the radiological standpoint, and pilocytic astrocytoma and meningioma on the cytological standpoint. However, our case was difficult to differentiate especially from high-grade glioma only by morphology, and immunohistochemistry including TTF-1 was helpful.

Abstract
Cervical dystonia, characterized by the involuntary contraction of cervical muscles, is the most common form of adult dystonia. In a patient with intractable cervical dystonia, we carried out a myotomy of the left obliquus capitis inferior and selective peripheral denervation (SPD) of the posterior branches of the C3-C6 spinal nerves based on preoperative 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT). The patient was a 65-year-old, right-handed man with an unremarkable medical history. His head rotated involuntarily to the left. Medication and botulinum toxin injections were ineffective, and surgical treatment was considered. 18F-FDG PET/CT imaging revealed FDG uptake in the left obliquus capitis inferior, right sternocleidomastoideus, and left splenius capitis. Myotomy of the left obliquus capitis inferior and SPD of the posterior branches of the C3-C6 spinal nerves was performed under general anesthesia. During the 6-month follow-up, the patient's Toronto Western Spasmodic Torticollis Rating Scale score improved from 35 to 9. This case shows that preoperative 18F-FDG PET/CT is effective in identifying dystonic muscles and determining the surgical strategy for cervical dystonia.

Abstract
OBJECTIVE Patients sometimes experience transient neurological events (TNEs) during the early postoperative period after revascularization surgery for childhood moyamoya disease. The clinical background and pathophysiology of TNEs remain unclear. This study aimed to evaluate the incidence rate of TNEs and discuss the factors associated with pediatric moyamoya disease. METHODS The authors retrospectively reviewed 110 cerebral hemispheres of 61 pediatric patients younger than 15 years who were treated from 2011 to 2020. All children underwent either simple double-direct or combined revascularization surgery. Of these 61 patients, 52 underwent bilateral surgery and 9 underwent unilateral surgery. The authors calculated the incidence of TNEs in accordance with a previously reported TNE definition. Cerebral blood flow (CBF) was evaluated in all eligible cases with xenon CT immediately after revascularization surgery. RESULTS The incidence rate of TNEs in patients with childhood moyamoya disease was 26.4%. TNEs occurred after an average (range) of 6.26 (2-12) days postoperatively without triggers, and all identified TNEs spontaneously resolved within 2 weeks. The most common symptoms were dysarthria, facial palsy, and numbness around the mouth, followed by sensory disturbance of the upper extremities. The presence of focal hyperperfusion on xenon CT performed immediately after revascularization surgery was strongly correlated with the incidence of TNEs (p = 0.0001). Focal hyperperfusion was observed in 43 of 110 operative sides (39.1%). Notably, only 25.6% of patients with focal hyperperfusion showed numerical global hyperperfusion. In addition, a decrease in CBF compared with the thalamic region in the contralateral side was observed in TNE-affected cases (p = 0.0443). CONCLUSIONS TNEs occurred more frequently in childhood moyamoya disease patients than expected. The clinical background, including symptoms, timing, and duration, was almost identical to TNEs in adults. Focal hyperperfusion, rather than numerical global hyperperfusion, was strongly correlated with the incidence of TNEs. Furthermore, the authors advocate the notion that a clinical course where symptoms occur without triggers may be a unique characteristic of TNEs, especially in childhood moyamoya disease.

Abstract
Various surgical treatments are available for occlusive subclavian and common carotid artery diseases. Nevertheless, to date, when cerebral endovascular treatment is utilized, revascularization via direct surgery may be required. This study reported five symptomatic cases of revascularization for CCA and SCA occlusive and stenotic lesions that were expected to be challenging to treat with endovascular treatment. We performed subclavian artery-common carotid artery or internal carotid artery bypass using artificial blood vessels or saphenous vein grafts in five patients with subclavian steal syndrome, symptomatic common carotid artery occlusion, and severe proximal common carotid artery stenosis. In this study, good bypass patency was achieved in all five cases. Although there were no intraoperative complications, one patient had a postoperative lymphatic leak. Moreover, there was no recurrence of stroke during postoperative follow-up for an average of 2 years. Conclusively, subclavian artery-common carotid artery bypass can be an effective surgical treatment for common carotid artery occlusion, proximal common carotid artery stenosis, and subclavian artery occlusion.

Abstract
INTRODUCTION With the advent of MR-guided focused ultrasound, the importance of the efficacy and safety of bilateral ventral intermediate (Vim) thalamotomy for essential tremor (ET) has increased. However, reports on bilateral Vim thalamotomy for ET remain scarce. METHODS To review the results and complications of bilateral Vim thalamotomy for the treatment of ET in the upper extremities, we retrospectively analyzed the patients with ET who underwent bilateral Vim thalamotomy with radiofrequency (RF) thermal coagulation. As bilateral simultaneous thalamotomy can cause surgical complications, thalamotomy was performed in stages. The interval between the first and second thalamotomies was 21.3 ± 14.7 months. We evaluated the efficacy using the Clinical Rating Scale for Tremor (CRST) before and after the first and second treatments, respectively. We also evaluated the complications before and after the first and second treatments, respectively. Moreover, we assessed the adverse events. RESULTS Seventeen patients were included in the study. The mean follow-up period following the second thalamotomy was 29.3 ± 15.0 months. The CRST part A + B scores were 34.9 ± 9.7, 20.8 ± 7.0, and 7.4 ± 6.8 before, following the first (40.4% improvement, p < 0.0001) and second thalamotomies (78.6% improvement, p < 0.0001), respectively. Nine patients presented with prolonged adverse events, including dysarthria, dysgeusia, dysphagia, tongue numbness, unsteady gait, and postural instability at the last available evaluation. All adverse events were mild and did not interfere with the patient's daily activities. DISCUSSION/CONCLUSIONS Bilateral Vim thalamotomy with RF thermal coagulation was an effective treatment for ET in both upper extremities. Despite most possible complications being mild, additional studies with a larger sample size are required to ensure patient safety.

Enterprise Treatment for Recurrent Basilar Tip Aneurysm after PulseRider-assisted Coil Embolization: A Case Report. NMC Case Rep J 2023; 10:115-119.

Abstract
PulseRider (Cerenovus, Irvine, CA, USA) is a relatively novel device used for the treatment of wide-neck aneurysms with a coil-assisted effect. However, treatment options for recurrent aneurysms after PulseRider-assisted coil embolization remain controversial. Here we report a case of recurrent basilar tip aneurysm (BTA) treated with Enterprise 2 after PulseRider-assisted coil embolization. A woman in her 70s underwent coil embolization for a subarachnoid hemorrhage with ruptured BTA 16 years ago. Recurrence was detected at 6-year follow-up, and an additional coil embolization was performed. Nevertheless, gradual recurrence still occurred, and PulseRider-assisted coil embolization was performed without any complications 9 years after the second treatment. However, recurrence was detected once more at 6-month follow-up. Thus, stent-assisted coil embolization using Enterprise 2 (Cerenovus) through PulseRider was selected for angular remodeling. Enterprise 2 was deployed between the right P2 segment of the posterior cerebral artery (PCA) and basilar artery (BA) after an effective coil embolization, which achieved effective angular remodeling between the right PCA and BA. The patient's postoperative course was uneventful, and no recanalization was detected after half a year. Although PulseRider is effective for wide-neck aneurysm treatment, recurrence remains a possibility. Additional treatment using Enterprise 2 is safe and effective with the expectation of angular remodeling.

Abstract
Background Reports on the long-term effects of pallidotomy for cervical dystonia remain scarce. Case Description We report a case of cervical dystonia successfully treated by unilateral pallidotomy. The patient was a 29-year-old man without past medical and family history of cervical dystonia. At the age of 28 years, neck rotation to the right with right shoulder elevation developed and gradually became worse. After symptoms failed to respond to repetitive botulinum toxin injections and oral medications, he underwent left pallidotomy, which resulted in significant improvement of cervical dystonia and shoulder elevation without surgical complications. At the 3-month evaluation, the symptoms completely improved. The Toronto Western Spasmodic Torticollis Rating Scale score dramatically improved from 39 points before surgery to 0 points at 7-year postoperative evaluation. Conclusion This case suggests that unilateral pallidotomy can be an alternative treatment option for cervical dystonia.

Abstract
This study evaluated whether cell sheets containing a network of lymphatic endothelial cells (LECs) promoted lymphangiogenesis after transplantation in vivo. Cell sheets with a LEC network were constructed by co-culturing LECs and adipose-derived stem cells (ASCs) on temperature-responsive culture dishes. A cell ratio of 3:2 (vs. 1:4) generated networks with more branches and longer branch lengths. LEC-derived lymphatic vessels were observed 2 weeks after transplantation of a three-layered cell sheet construct onto rat gluteal muscle. Lymphatic vessel number, diameter and depth were greatest for a construct comprising two ASC sheets stacked on a LEC/ASC (3:2 ratio) sheet. Transplantation of this construct in a rat model of femoral lymphangiectomy led to the formation of functional lymphatic vessels containing both transplanted and host LECs. Further development of this technique may lead to a new method of promoting lymphangiogenesis.

Abstract
Introduction
Glioblastoma has the poorest prognosis among brain tumors, and most cases recur. On the other hand, evidence of prognosis improvement by maximal surgical removal of the tumor is being established, and in recent years, new treatments such as temozolomide (2006), photodynamic therapy (2014), and TTF therapy (2018) were approved by insurance. and patient outcome has improved. In addition, molecular targeted therapy (bevacizumab approved in 2011) and immunotherapy are also used in clinical practice. In this study, we retrospectively analyzed the long-term treatment results of newly diagnosed glioblastoma cases treated at our facility, the correlation with the resection rate, and the treatment results by age and treatment method.
Methods
We retrospectively analyzed the clinical characteristics, resection rate, and treatment outcomes of adult patients with primary supratentorial glioblastoma who underwent surgery and treatment at our institution during the 20-year period from 2001 to 2021.
Results
493 cases, median age 58 years (18-85 years), 293 males and 200 females. The median and mean contrast-enhanced lesion resection rates in resection cases were 98% and 96.6%, respectively. Median PFS and OS for all patients (including biopsies) were 9.4 months and 22.7 months, respectively. The median OS for each age was 12.9 months, 22.9 months, 23 months, and 31.1 months when analyzed separately for 2001-2006, 2007-2010, 2011-2015, and 2016-2021 before TMZ. (p<0.0001), and treatment results improved with age. In particular, the median OS of 23 patients who combined PDT and autologous tumor vaccine (AFTV) was 63.1 months.
Conclusion
Treatment results for glioblastoma improve with age, and the time has come when we can aim for a 5-year survival rate of 50% by combining a high resection rate with multidisciplinary therapy including intraoperative MRI, PDT, AFTV and TTF.

Abstract
Abstract
Background
In the course of treatment of malignant gliomas, the appearance of contrast-enhanced lesions and surrounding T2/FLAIR high-signal after treatment is often experienced. There is no modality that can reliably diagnose whether the lesion is a recurrence or a response to treatment, including radiation necrosis. Furthermore, the choice of treatment modality is often difficult, such as reexcision, stereotactic irradiation, Avastin. Very few reports have examined the relationship between the irradiation field and histology.
Methods
Thirty-seven lesions in 30 patients who underwent repeat resection of malignant gliomas at our institution from October 2019 to December 2021 were analyzed retrospectively. Based on postoperative pathology, the patients were classified into two groups: recurrence group and radiation necrosis group.In each group, age, gender, histology at initial surgery, IDH status, radiation and chemotherapy, TNR of Methionine-PET, and the number of days after the end of treatment until the appearance of contrast lesions were considered.
Results
The recurrence group consisted of 20 patients with 26 lesions, mean age 48 years, male/female = 13/7, pathology was GBM 13, DA 1, AA 3, AO 2, AE 1, TNR 3.33 (1.41-6.32), and time to contrast appearance 547 (14-2427) days. PDT in combination with initial surgery was seen in 9 patients.The necrosis group consisted of 10 patients with 11 lesions, mean age 47 years, male/female = 4/6, pathology GBM 5, AA 2, AO 1, PXA 2. TNR 2.51 (1.20-3.75), 318 (24-678) days to contrast appearance, 2 patients had PDT.
Conclusions
Radiation necrosis tended to have lower TNR and shorter time to lesion appearance than recurrence, but no significant difference was observed. Improvement of diagnostic accuracy with modalities is desirable, and unnecessary irradiation is highly likely to contribute to ADL deterioration such as leukoencephalopathy and higher functional impairment.

Abstract
Abstract
Purpose
Intraoperative magnetic resonance imaging (MRI) update navigation is performed in all cases to preserve neurological function and remove the tumor as much as possible, and to prevent recurrence and improve prognosis. And under awake craniotomy, we supported operators by integrating preoperative functional images with intraoperative MRI. We report our usefulness of image superimposition between medium magnetic field intraoperative MRI and preoperative position emission tomography (PET) and preoperative diffusion tensor imaging (DTI) color-map.
Method
Of more than 2,200 cases using intraoperative MRI since 2000, 58 preoperative PET (57 methionine and 1 FDG nuclides) superimposed cases (32 left-sided, 35 males, 15 under awake craniotomy, mean 44.8 y.o.) were evaluated. The tumor was located to 34 frontal-, 12 temporal-, 10 parietal lobes, 1 insular gyrus, 1 thalamus. Color-map image superimposition of preoperative DTI (3T, 6-axis application) anisotropic indices in 12 cases (localized in 8 frontal-, 2 insular-, 2 parietal lobes, 7 left-sided, 7 females, mean 35 y.o.). Neurophysiological monitoring was combined (5 under general, 7 awake anesthesia).
Results
The preoperative TN ratio was 3.8 (in 57 methionine-PET cases), and pathological results (Grade 3-4 in 15-31 cases respectively, out of 54 cases) were used for reliable and preferential removal of sites with higher malignancy and recurrence-prone sites. Recurrent cases (41/58) had altered brain structures that were too difficult to identify without the navigation. In the DTI cases, intraoperative MRI, DTI color-map, and microscopic surgical images were displayed on one screen, and white matter tracts information as a reference is quickly conveyed to operators, and helped to reduce perioperative neurological complications.
Conclusion
Co-registering an effective superimposition of medium magnetic field intraoperative MRI with high positional accuracy, and preoperative PET- and DTI- images according to the patient's characteristics is currently the most practical navigation application method for intraoperative prediction of important functional information.

Abstract
Abstract
Introduction
Acquisition of somatic mutations is essential for the development of malignant tumors such as diffuse gliomas. Recent single-cell analyses have pointed out the importance of somatic mosaicism in the pathogenesis of cancer. Here we report a case of IDH (isocitrate dehydrogenase)-mutant astrocytoma that has relapsed after intensive chemoradiation with somatic mosaicism for the IDH1 R132H mutation.
Clinical and Pathological Findings
A 36-year-old male presented with epileptic symptoms and a mass lesion in the right frontal lobe. A needle biopsy demonstrated IDH-mutant astrocytoma (grade 2). At the age of 41, relapsed tumor was completely resected, and the tumor cells were diffusely positive for IDH1 R132H with grade 4 morphology. Chemoradiotherapy (PAV + IMRT 60Gy/30fr) was added, but contrast-enhanced lesions reappeared 5 months after the initial surgery. The re-excised specimen was grade 4 astrocytoma, and the number of IDH1 R132H-positive tumor cells was very small compared to the total number of tumor cells, suggesting somatic mosaicism for IDH mutations.
Conclusion
It is imperative to clarify the induction mechanism and significance of somatic cell mosaicism in cancer, and molecular genetic assessment with sequencing and digital PCR would be necessary in addition to immunostaining for accurate molecular diagnoses of the brain tumors.
