Abstract
Intracerebral hemorrhage (ICH) represents one of the most severe subtypes of stroke. Due to the complexity of the brain injury mechanisms following ICH, there are currently no effective treatments to significantly improve patient functional outcomes. Curcumin, as a potential therapeutic agent for ICH, is limited by its poor water solubility and oral bioavailability. In this study, mPEG-PCL is used to encapsulate curcumin, forming curcumin nanoparticles, and utilized the intranasal administration route to directly deliver curcumin nanoparticles from the nasal cavity to the brain. By inhibiting pro-inflammatory neuroinflammation of microglia following ICH in mice, reprogramming pro-inflammatory microglia toward an anti-inflammatory function, and consequently reducing neuronal inflammatory death and hematoma volume, this approach improved blood-brain barrier damage in ICH mice and promoted the recovery of neurological function post-stroke. This study offers a promising therapeutic strategy for ICH to mediate neuroinflammatory microenvironments.

Abstract
BACKGROUND Although a benign intracranial tumor, craniopharyngioma treatment has always been considered a challenging clinical problem. Recently, BRAF V600E mutation in the pathogenesis of papillary craniopharyngioma (PCP) has been further revealed. Thus, BRAF inhibitors (BRAFi) serve as an applicable treatment for patients with PCP. METHODS Two patients with recurrent PCP were treated with combined BRAFi dabrafenib (150 mg, orally twice daily) and MEK inhibitors (MEKi) trametinib (2 mg, orally twice daily). A follow-up exceeding 2 years was conducted. We meticulously scrutinized the treatment's safety and efficacy profiles by delving into existing literature. RESULTS One patient harboring a solid tumor achieved a complete tumor response devoid of any adverse events and encountered no recurrence over 2 years subsequent to discontinuation. Moreover, within a mere month of commencing targeted therapy, the tumor demonstrated observable shrinkage. This finding substantiates the considerable potential inherent in targeted therapy for PCP cases marked by the somatic BRAF V600E mutation. CONCLUSIONS Under specific conditions, individuals diagnosed with PCP can attain a complete tumor response following combined treatment with BRAFi/MEKi.

Abstract
Desloratadine, a second generation H1-antihistamine, is generally considered to be safe. We found only one article reporting four children with a family or disease history of epilepsy who developed the condition after desloratadine treatment, with all four patients recovering well. Here we describe a healthy boy who developed left-arm convulsions on day 68 after taking desloratadine, at which point the desloratadine treatment was immediately stopped. Investigations were completed on day 83 and the patient was diagnosed with epilepsy. He was prescribed sodium valproate combined with oxcarbazepine, topiramate, lamotrigine and clonazepam for 15 months, which did not control the convulsions. During the following 3 months the patient received sodium valproate combined with lacosamide, and on day 615 the seizures stopped and no further convulsions occurred. At the follow-up, his father reported that the boy's memory was not as good as it had been previously. The convulsions continued after the withdrawal of desloratadine; therefore, the pathological mechanism of convulsion and the treatment plan need further research.

Abstract
Despite improvements in microscopically neurosurgical techniques made in recent years, the prognosis of adamantinomatous craniopharyngioma (ACP) is still unsatisfactory. Little is known about cellular atlas and biological features of ACP. Here, we carried out integrative analysis of 44,038 single-cell transcriptome profiles to characterize the landscape of intratumoral heterogeneity and tumor microenvironment (TME) in ACP. Four major neoplastic cell states with distinctive expression signatures were defined, which further revealed the histopathological features and elucidated unknown cellular atlas of ACP. Pseudotime analyses suggested potential evolutionary trajectories between specific neoplastic cell states. Notably, a distinct oligodendrocyte lineage was identified in ACP, which was associated with immunological infiltration and neural damage. In addition, we described a tumor-centric regulatory network based on intercellular communication in TME. Together, our findings represent a unique resource for deciphering tumor heterogeneity of ACP, which will improve clinical diagnosis and treatment strategies.

Abstract
Current treatment of glioma is hampered due to the physical blood-brain barrier (BBB) and the resistance to traditional chemotherapeutic agents. Herein, we proposed a combined treatment strategy based on Cyclo (Arg-Gly-Asp-d-Phe-Lys) (cRGDfk) peptides-modified nanoparticle named cRGD-P in a self-assembly method for the co-delivery of doxorubicin (DOX) and BRD4 PROTAC degrader ARV-825 (ARV). Molecular dynamics simulations showed that cRGD-P could change its conformation to provide interaction sites for perfectly co-loading DOX and ARV. The cRGD-P/ARV-DOX exhibited an average size of 39.95 nm and a zeta potential of −0.25 mV. Increased expression of BRD4 in glioma cells was observed after being stimulated by cRGD-P/DOX, confirming one of the possible mechanisms of DOX resistance and the synergistic tumor inhibition effect of BRD4 degrading ARV combined with DOX. In the study, the combination of DOX and ARV in the cRGD-P nanoparticle system exhibited synergistic suppression of tumor growth in glioma cells on account of cell cycle arrest in the G2/M phase and the activation of tumor cells apoptosis-related pathways including triggering caspase cascade and downregulating Bcl-2 as well as upregulating Bax. The cRGD-P/ARV-DOX system could effectively suppress the heterotopic and orthotopic growth of glioma by increasing tumor apoptosis, inhibiting tumor proliferation, and decreasing tumor angiogenesis in vivo. Therefore, the cRGD-modified nanoparticle to co-deliver DOX and ARV provides a potential platform for exploiting a more effective and safer combination therapy for glioma.

Abstract
RATIONALE Benign optic nerve gliomas were rarely found in adults, and total resection of these lesions seems impossible. We aimed to share a rare clinical case with an unusual and instructive treatment process. PATIENT CONCERNS A 52-year-old woman complained of a 4-month history of visual disturbance. Automated perimetry revealed visual field defect in her both eyes. DIAGNOSIS This patient was diagnosed with optic nerve glioma. We found its pathological features consistent with the pilocytic astrocytomas (WHO grade I). INTERVENTIONS A total resection of the tumor was smoothly performed. OUTCOMES Repeat MRI 3 months after the surgery demonstrated no recurrence of the lesion. Two years of postoperative telephone follow-up showed a stable status of improved vision. LESSONS We reported this interesting case to show a rare kind of condition regarding optic nerve gliomas in adults, which might help neurosurgeons like us to diagnose and treat these "invisible" tumors.

Abstract
Objective Lactate dehydrogenase (LDH) has been reported to be associated with outcomes after surgery in patients with aneurysmal subarachnoid hemorrhage (aSAH), but it is unclear if this is independent from other biomarkers and across all aSAH treatments. This study aims to assess whether LDH is an independent predictor of mortality in patients with aSAH and test whether the inclusion of LDH in a well‐established prediction model can improve discrimination and reclassification. Methods This was a retrospective observational study at a tertiary academic medical center. This study measured baseline LDH levels taken at admission and longitudinal LDH levels (up to a month postadmission) to assess median, max, and trajectory LDH levels. The primary outcome was mortality at 90 days. Multivariable regression analyses were used to evaluate associations between LDH and outcomes. The full original Subarachnoid Hemorrhage International Trialists' (SAHIT) model was used as the reference model. Results In total, 3524 patients with aSAH were included. LDH at admission was independently associated with mortality at 90 days (quartile 4 vs. 1: odds ratio 1.60; 95% CI 1.08–2.37) and mortality at the longest follow‐up (quartile 4 vs. 1: hazard ratio1.72; 95% CI 1.34–2.20). Compared with the SAHIT model, the addition of three LDH (admission, max, and median) levels to the SAHIT model significantly improved the area under the curve and categorical net reclassification improvement for prediction mortality. Interpretation In patients with aSAH, LDH level is an independent predictor of all‐cause mortality. The incorporation of LDH into a well‐established prediction model improved the ability to predict the risk of death in patients with aSAH.

Abstract
Most studies on pigmented villonodular synovitis (PVNS) of the temporomandibular joint (TMJ) with skull base extension mostly are case report. Here, we summarize the clinical features, treatments, and outcomes of PVNS of the TMJ with skull base extension in a large case series. We reviewed the clinical information relating to patients diagnosed with PVNS of the TMJ with skull base extension information of patients in our center between 2011 and 2020. We reviewed 10 patients (4 males and 6 females). All cases had presented with a unilateral lesion extending the middle skull base. PVNS of the TMJ with skull base extension occurred on the left side in 6 patients (60%) and on the right side in 4 patients (40%). Of the 10 patients, pain and mass were the most prevalent symptoms. All patients received surgery and no recurrence was seen after 35.90 ± 25.35 months follow-up. Despite destructive biological behavior, surgery can achieve an excellent outcome for patients with PVNS of the TMJ with skull base extension. An en bloc resection may prevent recurrence and provide long-term relief. Radiotherapy may be reserved for subtotal excision and recurrent lesions but require further investigation.

Abstract
Lymphoplasmacyte-rich meningioma (LRM) is a rare histologic subtype of meningioma. Creeping-growth pattern is uncommon in meningioma, and the mechanism is unclear. Here, we report a 44-year-old man presented with extremities weakness for 2 months and incontinence for 2 weeks. Head and neck MRI revealed diffuse creeping-growth nodular meningeal masses with skull base, tentorium, sella area, and C1-6 vertebral plane involvement. An operation was carried out, cervical and lower clivus part of the lesion was resected, but gross total resection could not be achieved due to the widespread lesions. Pathologic examination revealed the diagnosis of LRM. The patient is free from progression clinically 3 months postoperatively. We also conducted a systematic literature review about LRM with creeping-growth pattern. A total of only nine cases (including the present case) of creeping-growth LRMs were included and analyzed in terms of clinical manifestations, radiological features, treatment, and outcome. LRMs show a higher rate (7.5%) of creeping-growth pattern than other types of meningiomas. The average creeping length of all creeping-growth LRMs was 11.4 ± 10.9 cm (range, 3–30 cm). Most cases (66.7%) had obvious peritumoral edema. Total removal rate is low (33.3%), and two of them (22.2%) received biopsy, followed by steroids treatment (or further immunosuppressive drugs therapy) and radiotherapy. The recurrence rate is higher than conventional LRMs (22.2 vs. 11.3%), and one patient (11.1%) died 11 months after treatment. Creeping-growth pattern in LRM may be considered as a general radiologic variant. The recurrence rate is higher compared with LRM with round/swelling pattern. We speculated that the pathogenesis of creeping growth in LRM may be associated with damage of lymphatic systems of the central nervous system.

Abstract
Background Craniopharyngioma (CP) is rare histologically benign but clinically challenging tumor because of its intimate relationship with the critical structure in the central brain. CP can be divided into two major histologic subtypes: adamantinomatous-type CP (ACP) and papillary-type CP (PCP). Although some genetic aberrations for both categories have been revealed in previous studies, the complete spectrum of genetic changes of this tumor remains unknown. Methods In this study, we conducted whole genome sequencing (WGS) on twenty-six CPs including 16 ACPs and 10 PCPs together with their matched blood samples. Somatic variants (SNVs, InDels, SVs and CNVs) were identified and mutational signatures were characterized for each patient. We investigated the impact of a novel CTNNB1 mutant on its protein stability, ubiquitination and Wnt pathway activity. Cell proliferation ability of the CTNNB1 mutant in ACP primary cells was additionally analyzed by CCK8 and colony formation assays. Results We found that CPs had showed less complexity with fewer somatic mutations compared with malignant tumors. Moreover, mutations in CTNNB1 (68.75% of ACP) and BRAF V600E (70.00% of PCP) are mutually exclusive in ACP and PCP, consolidating that the driving roles of these two genes in ACP and PCP, respectively. A novel mutation in the exon 3 of CTNNB1 which compromised both a transversion and in-frame deletion was identified in ACP. This mutation was experimentally validated to confer β-catenin increased stability by inhibiting its ubiquitination, thus activating Wnt-signaling pathway and promoting cell proliferation. Conclusions Whole genome landscape for CP was revealed by WGS analysis, and a novel mutation in the exon 3 of CTNNB1 was identified. This novel mutation activates Wnt-signaling pathway through increasing the stability of β-catenin. Our findings provided us with more comprehensive insight into the spectrum of genetic alterations in CP.

Abstract
Because of their high specificity and low side effects, protein drugs possess a substantial global market. However, the low bioavailability of protein is still a major obstacle to their expanded applications, which is expected to be answered with proper protein formulations. Taking corneal neovascularization (CNV) as an example, we demonstrated a co-assembled system of hexa-histidine and Ava (Avastin) with metal ions (HmA@Ava) could cross the cornea, the most important bio-barrier during the treatment of most diseases of the anterior segment in clinics. We found that the nanosized HmA@Ava efficiently encapsulated Ava with impressive loading capacity without destroying the bioactivity of Ava and assisted Ava penetration through the corneal barriers to effectively inhibit CNV development in an alkali burn rat model with sustained and pH-dependent Ava release. Our results suggested that the co-assembled strategy of protein and HmA is a proper formulation to protein drugs, with promising penetration ability to deliver protein across bio-barriers, which could open a path for topical administration of protein drugs for treatment of various ocular diseases and hold enormous potential for delivery of therapeutic proteins not only for ocular diseases but also for other diseases that require protein treatment. HmA@Ava can bring protein drug, Ava, across over the primary bio-barrier of the anterior segment and efficiently treat CNV. HmA@Ava was nanoparticles, with impressive loading capacity without destroying bioactivity of Ava and strong pH-dependent release. HmA can open a path for the treatment of eye diseases and hold huge potential to protein drugs to other diseases.

Abstract
Background Previous reports about risk factors for linezolid-induced thrombocytopenia have been insufficient, often due to the variability in study design and population, and some factors have not yet been studied. Aim The aims of this study are to determine potential risk factors for linezolid-induced thrombocytopenia, and to analyze the influencing factors of different thrombocytopenia definitions. Method This retrospective study involved patients who were administered intravenous linezolid for ≥ 1 day between January 1, 2015 and January 1, 2021. Their demographic and clinical data were extracted from electronic medical records. Thrombocytopenia was defined as: ①thrombocytopenia with platelet count < 100 × 109/L and a decrease in 25% or more from baseline of the platelet count (criterion 1); ②thrombocytopenia due to a platelet count drop decrease of 25% or more from baseline (criterion 2). Risk factors were determined via binary logistic regression analysis. Results This study included 320 patients. Binary logistic regression analysis indicated that baseline platelet count (p < 0.001), linezolid therapy duration (p = 0.001) and shock (patients require vasoactive medications) (p = 0.019) were independent risk factors for criterion-1thrombocytopenia, while linezolid therapy duration (p < 0.001) and shock (p = 0.015) were independent risk factors for criterion-2 thrombocytopenia. There was also a significant correlation between shock and early-onset thrombocytopenia (p = 0.005 and 0.019 for criterion 1 and criterion 2, respectively). Conclusion Linezolid therapy duration and shock were common causes of different thrombocytopenia definitions; shock was correlated with early-onset thrombocytopenia. Platelet count should be monitored during linezolid therapy especially during long-duration therapy and in shock patients.

Abstract
PURPOSE Accumulating evidence indicates that genetic polymorphisms in ATP-binding cassette superfamily members, such asABCC2 and ABCG2, alter responses to antiepileptic drugs (AEDs); however, this evidence is controversial and inconclusive. To provide strong evidence of the association between common polymorphisms in ABCC2 and ABCG2 and AED responses in patients with epilepsy, we performed a systematic review and meta-analysis. METHODS A literature search of electronic databases (PubMed, EBSCO, Ovid and the China National Knowledge Infrastructure) was performed. To evaluate the association of genetic polymorphisms inABCC2 and ABCG2 and risk of AED treatment, we calculated pooled odds ratios (ORs) and 95 % confidence intervals (CIs) using a fixed- or random-effect model. RESULTS A significant association of theABCC2 rs717620 polymorphism with resistance to AEDs was found in the overall pooled populations (homozygous comparison: OR = 1.77, 95 % CI, 1.27-2.48; dominant model: OR = 1.23, 95 % CI, 1.06-1.43; recessive model: OR = 1.75, 95 % CI, 1.28-2.40) and Asians (dominant model: OR = 1.21, 95 % CI, 1.03-1.42; recessive model: OR = 1.80, 95 % CI, 1.30-2.50). Using a recessive model, a similarly significant association of ABCC2 rs3740066 with AED resistance was observed in the overall pooled populations (OR = 2.29, 95 % CI, 1.44-3.64) and Asians (OR = 2.53, 95 % CI, 1.56-4.08). However, ABCC2 rs2273697, ABCG2 rs2231137 and rs2231142 were not found to be associated with AED responsiveness. CONCLUSION This meta-analysis suggests thatABCC2 rs717620 and rs3740066 are risk factors that predict responses to AEDs in epileptic patients.

Abstract
OBJECTIVE Seizures are common complications following intracranial aneurysms and present a greater risk to pediatric patients than adults. Though the risk factors of seizures in adults with intracranial aneurysms have been well documented, the risk factors in pediatric patients remain unknown. The aim of this study was to evaluate the risk factors for preoperative seizures and the effect of the treatment approach on postoperative seizures in pediatric patients with intracranial aneurysms. PATIENTS AND METHODS The data of 64 pediatric patients (mean age 11.4 ± 5.7 years; 68.8 % of males) with intracranial aneurysms were retrospectively analyzed from January 2012 to April 2017. Comparisons were made between patients with preoperative seizures (case group) and those without (control group). RESULTS Twenty-four patients (37.5 %) had preoperative seizures, and 15 patients (23.4 %) had postoperative seizures. Multiple logistic regression analysis revealed that younger age (0-5 years), head trauma history, ruptured aneurysms, lobe hematomas, modified Fisher grade 3-4, giant aneurysms, pseudoaneurysms and distal arterial aneurysms were independently associated with the increased risk of preoperative seizures. Patients in the surgical and endovascular groups did not differ significantly in the rates of preoperative seizures or early postoperative seizures (within 1 month) (P > 0.05). However, a significantly lower incidence of late postoperative seizures (1-3 months and 3-6 months) was observed in the surgical group compared with the endovascular group (P < 0.05). CONCLUSION Pediatric patients with intracranial aneurysms are at high risk for seizures. Risk factors for preoperative seizures included younger age (0-5 years), head trauma history, lobe hematomas, modified Fisher grade 3-4, giant aneurysms, pseudoaneurysms and distal arterial aneurysms. Compared with the endovascular treatment, surgical intervention provided more benefits with regard to reducing the risk of late postoperative seizures.

Abstract
Objective The aims of this study were to identify the influencing factors such as gender, age, dose and combinations of other antiepileptic drugs (AEDs), especially in triple combinations on the pharmacokinetic of Lamotrigine (LTG) in epilepsy patients of Northwest Chinese Han population. Methods Data of the LTG concentration and clinical information were analyzed retrospectively from a therapeutic drug monitoring (TDM) database at the Clinical Pharmacy Laboratory of Xi’an Central Hospital between January 1, 2016 and January 1, 2018. The independent-sample t-test, one-way ANOVA analysis and Bonferroni and Tamhane T3 post-hoc test, the stepwise multivariate regression analysis were adopted by IBM SPSS, version 22.0. Results 226 serum samples met the inclusion criteria and were evaluated. The mean LTG serum concentration was 5.48±3.83 μg/mL. There were no gender differences (P = 0.64), and there were no significant effects by age on LTG serum concentration after age stratification (3–14 years old, 14-45 years old, 45–59 years old) (P = 0.05). Multiple regression analysis showed that the daily LTG dose and co-administration of other AEDs significantly affected LTG serum concentrations. Combination with enzyme-inducer AEDs, the mean steady-state LTG concentration could be decreased by 30.73% compared with LTG monotherapy. Among enzyme-inducer AEDs, particularly strong inducer Carbamazepine (CBZ) could decrease the mean LTG concentration by 53.65%, but weak inducer AEDs such as Oxcarbazepine (OXC) and Topiramate (TPM) had no effect, Valproic acid (VPA) could increase the mean LTG concentration by 93.95%, and the inducer only partially compensated for the inhibitory effect of VPA in triple combination. Conclusions There were no significant gender and age effects, but the LTG daily dose and co-administration of other AEDs significantly affected LTG serum concentration. Combination with enzyme-inducer AEDs, especially CBZ could significantly decrease LTG serum concentrations, VPA could significantly increase LTG serum concentrations, and the inducer only partially compensated for the inhibitory effect of VPA in triple combination. In the clinical setting, these findings can help to estimate LTG concentrations and adjust dosage and evaluate adverse drug reactions.

Abstract
BACKGROUND Hydrocephalus is a well-recognized complication after aneurysmal subarachnoid hemorrhage (aSAH). This study aimed to identify predictors for shunt-dependent hydrocephalus (SDHC) after aSAH via a systematic review and meta-analysis. METHODS A systematic search was conducted using the Embase, MEDLINE, and Web of Science databases for studies pertaining to aSAH and SDHC. Risk factors were assessed by meta-analysis when they were reported by at least 2 studies. The results were presented as odd ratios or risk ratios according to the study design with the corresponding 95% confidence intervals (CI). RESULTS Twenty-five studies were included. In primary analysis of 14 potential risk factors, 12 were identified as predictors of SDHC after aSAH including age ≥50 years, female gender, high Hunt-Hess grade, Glasgow Coma Scale ≤8, Fisher grade ≥3, acute hydrocephalus, external ventricular drainage insertion, intraventricular hemorrhage, postcirculation aneurysm, anterior communicating artery aneurysm, meningitis, and rebleeding. The meta-analysis based on cohort studies found a significantly increased risk for SDHC in patients with aSAH treated by coiling (risk ratio, 1.16; 95% CI, 1.05-1.29), while the meta-analysis based on case-controlled studies failed to replicate this finding (odds ratio, 1.27; 95% CI, 0.95-1.71). CONCLUSIONS Several new predictors of SDHC after aSAH were identified that may assist with the early recognition and prevention of SDHC. The controversial evidence found in this study was insufficient to support the potential of neurosurgical clipping for reducing the risk of shunt dependency. Further well-designed studies are warranted to explore the effect of treatment modality on SDHC risk.

Abstract
The plasminogen activator inhibitor-1 (PAI-1) is a candidate gene for stroke based on PAI-1's crucial role in fibrinolytic system. However, association studies have yielded conflicting results regarding the association between PAI-1 polymorphisms and stroke susceptibility. To further elucidate the putative association, we performed a systematic review and meta-analysis to provide a complete picture of the loci investigated for association of PAI-1 polymorphism with stroke risk and to derive a precise estimation. PubMed, Embase, and China National Knowledge Infrastructure (CNKI) databases were searched until June 2015 to identify eligible studies. Forty data sets from 39 studies with a total of 8336 cases and 14,403 controls were included. The most commonly investigated polymorphism was -675 4G/5G, followed by -844 G/A, 11053 T>G, HindIII C/G, and (CA)n. Overall, our meta-analysis provided evidence for the significant association of PAI-1 4G/5G polymorphism with an increased risk of adult but not pediatric ischemic stroke (adult: 4G/4G vs. 4G/5G + 5G/5G, OR = 1.21, 95 % CI = 1.04-1.42). In the subgroup analysis, significant association was detected in Asians (4G/4G vs. 4G/5G + 5G/5G, OR = 1.45, 95 % CI = 1.14-1.85) but not Caucasians. Moreover, we found that -844 G/A but not 11053 T>G polymorphism was associated with an increased risk of ischemic stroke (-844G/A: A/A vs. G/G: OR = 1.32, 95 % CI = 1.01-1.73). A tendency of PAI-1 4G/5G polymorphism towards a decreased risk of hemorrhagic stroke was observed (4G/4G + 4G/5G vs. 5G/5G, OR = 0.77, 95 % CI = 0.59-1.02, P = 0.066). Future well-designed studies in large well-characterized sample size and presenting results stratified by gender, age, and stroke subtype are warranted.

Abstract
Background Spontaneous intracerebral hemorrhage is a disease with high morbidity, high disability rate, high mortality, and high economic burden. Whether patients can benefit from surgical evacuation of hematomas is still controversial, especially for those with moderate-volume hematomas in the basal ganglia. This study is designed to compare the efficacy of endoscopic surgery and conservative treatment for the moderate-volume hematoma in spontaneous basal ganglia hemorrhage. Methods Patients meet the criteria will be randomized into the endoscopic surgery group (endoscopic surgery for hematoma evacuation and the best medical treatment) or the conservative treatment group (the best medical treatment). Patients will be followed up at 1, 3, and 6 months after initial treatment. The primary outcomes include the Extended Glasgow Outcome Scale and the Modified Rankin Scale. The secondary outcomes consist of the National Institutes of Health Stroke Scale and the mortality. The Barthel Index(BI) will also be evaluated. The sample size is 100 patients. Discussion The ECMOH trial is a randomized controlled trial designed to evaluate if endoscopic surgery is better than conservative treatment for patients with moderate-volume hematomas in the basal ganglia.

Abstract
Mature cystic teratoma (dermoid cyst) inside the Sylvian fissure is rare. A 14-year-old boy presented with 2 episodes of generalized tonic-clonic seizures. Using a fat-suppressed, T1-weighted sequence, magnetic resonance imaging revealed a hypointense nonenhancing mass in the left Sylvian fissure. He underwent left pterional craniotomy for total tumor resection. The pathological diagnosis was mature cystic teratoma (dermoid cyst). Headache and seizures are the leading symptoms. Cyst rupture causes inflammation of cholesterol crystals, and the cyst contents may cause seizure. Surgical resection is the treatment of choice, but radical resection is not advised if critical neurovascular structure can be injured.
