Arteriovenous malformations (AVMs) are abnormal connections of arteries and veins without intermediate capillary components. As such, AVMs can remain asymptomatic or have a variety of clinical presentations ranging from mild headaches to severe symptoms like seizures, hemorrhage, and subsequent coma. Papilledema and increased intracranial pressure without hydrocephalus or hemorrhage are rare forms of presentations of cerebral AVM. The mechanism of intracranial hypertension accompanying brain AVMs is not entirely understood, and the right treatment strategy is controversial. Here, we present the treatment and outcomes of four patients with unruptured AVMs who presented with intracranial hypertension accompanied by visual symptoms, papilledema, and without evidence of hydrocephalus. In cases of AVMs accompanied by intracranial hypertension, AVM treatment should be considered the main target of management.

动静脉畸形(AVM)是动脉和静脉的异常连接,中间没有毛细血管成分。因此,动静脉畸形可以没有症状,也可以有各种临床表现,从轻微头痛到癫痫发作、出血和随后昏迷等严重症状。无脑积水或出血的乳头水肿和颅内压增高是脑动静脉畸形的罕见表现形式。脑动静脉畸形伴发颅内高压的机制尚未完全明了,正确的治疗策略也存在争议。在此,我们介绍了四例伴有颅内高压、视觉症状、乳头水肿且无脑积水证据的未破裂脑动静脉畸形患者的治疗方法和结果。对于伴有颅内高压的 AVM 病例,应将 AVM 治疗作为主要治疗目标。

Aim: To investigate the prognostic implication (mortality at 3 months) of acute kidney injury (AKI) in acute ischemic stroke treated with mechanical thrombectomy (MT).

Material and methods: A literature search was performed using PubMed/OVID/Cochran's CENTRAL database (time frame: inception to January 2023). Study characteristics, patient status, clinical outcomes, AKI incidence, and sample size were recorded. The exclusion criteria were non-English literature, no human subjects, and <10 patients as the sample size. Studies were assessed using the MINORS/GRADE system. Meta-analysis and meta-regression with a random-effects model were performed.

Results: 3314 studies were retrieved. After applying the exclusion criteria, the final population included of 18/3314 studies (0.5%). Among them, only 6/18 (33.3%) studies reported results in two separate groups (AKI vs non-AKI), allowing for inference statistics for a total population of 3229 (538.6 ± 403.7). The I^2 was 34.6 and Q's Cochrane was 7.80. The pooled odds ratio (OR) for mortality at 3 months in patients with AKI was 5.8 (95% confidence interval [95% CI] 95% CI 3.62 to 9.52). Leave-one-out meta-analysis showed no significant sources of heterogeneity. In the meta-regression, diabetes prevalence was associated with a higher mortality rate (OR 1.14, 95% CI 1.03 to 1.28), and lower age and a small amount of contrast media were negatively correlated (0.91 [95% CI 0.83 to 0.99] and OR 0.97 [95% CI 0.94 to 1.00], respectively).

Conclusion: AKI was significantly associated with the mortality rate in MT-treated stroke patients (OR 5.8 [95% CI 3.62 to 9.36]).

目的:研究急性缺血性脑卒中机械性血栓切除术(MT)治疗后急性肾损伤(AKI)的预后影响(3个月时的死亡率):使用 PubMed/OVID/Cochran's CENTRAL 数据库进行文献检索(时间范围:开始至 2023 年 1 月)。记录了研究特点、患者状况、临床结果、AKI发生率和样本量。排除标准为非英文文献、无人类受试者和结果:共检索到 3314 项研究。采用排除标准后,最终纳入的研究为 18/3314 项(0.5%)。其中,只有 6/18(33.3%)项研究报告了两个独立组(AKI 与非 AKI)的结果,因此可以对 3229 人(538.6 ± 403.7)进行推断统计。I^2为34.6,Q's Cochrane为7.80。AKI患者3个月时的死亡率的汇总几率比(OR)为5.8(95%置信区间[95% CI] 95% CI 3.62至9.52)。剔除荟萃分析显示没有明显的异质性。在荟萃回归中,糖尿病患病率与较高的死亡率相关(OR 1.14,95% CI 1.03 至 1.28),而较低的年龄与少量造影剂呈负相关(分别为 0.91 [95% CI 0.83 至 0.99] 和 OR 0.97 [95% CI 0.94 至 1.00]):结论:AKI 与 MT 治疗脑卒中患者的死亡率密切相关(OR 5.8 [95% CI 3.62 至 9.36])。

Rosai-Dorfman Disease (RDD), also known as sinus histiocytosis with massive lymphadenopathy, is a rare non-Langerhans cell histiocytic neoplasm. Although the disease classically presents as massive painless lymphadenopathy in young adults, RDD can also involve the central nervous system in some patients. CNS lesions, can cause headaches, neurologic deficits, and even neurologic deficits. The imaging appearance of CNS RDD typically mimics that of meningiomas: well-circumscribed dural-based lesions that often have dural tails. However, some imaging clues also exist that might help a radiologist recognize RDD, even before histopathologic confirmation. This radiology-pathology report of a patient with CNS RDD highlights the most pertinent clinical, imaging, and pathologic features of CNS RDD, and discusses what the neuroradiologist needs to know about the disease.

罗赛-多夫曼病(Rosai-Dorfman Disease,RDD)又称窦性组织细胞增生症伴巨块淋巴结病,是一种罕见的非朗格汉斯细胞组织细胞肿瘤。虽然该病在青壮年中通常表现为大量无痛性淋巴结病,但有些患者的中枢神经系统也会受累。中枢神经系统病变可导致头痛、神经功能缺损,甚至神经功能障碍。中枢神经系统 RDD 的影像学表现通常与脑膜瘤相似:以硬脑膜为基础的圆形病变,通常有硬脑膜尾部。不过,也有一些影像学线索可以帮助放射科医生识别 RDD,甚至在组织病理学确诊之前。这篇中枢神经系统 RDD 患者的放射病理报告强调了中枢神经系统 RDD 最相关的临床、影像和病理特征,并讨论了神经放射科医生需要了解的疾病相关知识。

To date, the use of the most suitable first-pass technique for Mechanical Thrombectomy is still debated. In last years, several observational studies have suggested noninferiority or superiority of A Direct Aspiration first-Pass Technique (ADAPT) technique to achieve better reperfusion in comparison to stent retriever. While ASA/AHA 2018 guidelines recommend that patients with AIS should receive Mechanical Thrombectomy with a stent retriever, last European Stroke Organization guidelines report no evidence that stent retriever compared with contact aspiration could improve reperfusion rate. ADAPT is based on aspiration alone as the primary mechanism of thrombectomy and, if initially unsuccessful, then incorporating adjunctive alternatives. ADAPT improvement is also related to last generation of aspiration catheters. The purpose of this review is to report ADAPT principles, technique, efficacy, and safety as first-line treatment for acute ischemic stroke with the latest generation of reperfusion devices.

迄今为止,如何使用最合适的机械血栓切除术首通技术仍存在争议。近年来,多项观察性研究表明,直接抽吸第一道血栓技术(ADAPT)在实现更好的再灌注方面与支架回流器相比并不逊色或更具优势。虽然 ASA/AHA 2018 指南建议 AIS 患者应接受带支架回吸器的机械血栓切除术,但欧洲卒中组织最新指南报告称,没有证据表明支架回吸器与接触式抽吸相比能提高再灌注率。ADAPT 的基础是仅将抽吸作为血栓清除的主要机制,如果最初不成功,则采用辅助性替代方法。ADAPT 的改进也与上一代抽吸导管有关。本综述旨在报告 ADAPT 的原理、技术、疗效和安全性,作为使用最新一代再灌注设备治疗急性缺血性卒中的一线治疗方法。

Objective: This systematic review aimed to evaluate the published cases with miliary brain lesions and their etiological factors, clinical manifestations, diagnostic procedures, and outcomes.

Methods: A comprehensive search of PubMed, Scopus, Embase, and Google Scholar was conducted using the specified search strategy. Eligibility criteria included cases with miliary lesions in the brain confirmed through neuroimaging and various diagnostic procedures. The PRISMA guidelines were followed, and the PROSPERO registration number for the protocol is CRD42023445849.

Results: Data from 130 records provided details of 140 patients. Tuberculosis was the primary cause in 93 cases (66.4%), malignancies in 36 cases (25.7%), and other causes accounted for the remaining 11% cases. Tuberculosis patients averaged 35.7 years old, while those with malignancies averaged 55.44 years. Tuberculosis symptoms primarily included fever, headache, and altered sensorium, whereas malignant cases often exhibited progressive encephalopathy, headache, and specific neurological deficits. Distinctive indicators for CNS tuberculosis were choroidal tubercles and paradoxical reactions. Additionally, 63 tuberculosis patients showed miliary lung shadows and 49 had abnormal CSF findings. For the malignancy group, 13 exhibited miliary lung lesions, and 8 had CSF abnormalities. Regarding outcomes, a significant mortality disparity was observed, with 58.3% in the malignancy group, compared to 10.8% in the tuberculosis group and 27.3% in other cases.

Conclusion: Miliary brain lesions are a crucial imaging abnormality that necessitates prompt work up. In an immunocompromised state, diagnostic possibilities of miliary brain lesions are more varied and often pose a bigger challenge.

目的本系统综述旨在评估已发表的脑部淤积性病变病例及其病因、临床表现、诊断程序和结果:方法:采用指定的检索策略对 PubMed、Scopus、Embase 和 Google Scholar 进行了全面检索。符合条件的病例包括通过神经影像学检查和各种诊断程序确诊的脑部淤积性病变。研究遵循PRISMA指南,方案的PROSPERO注册号为CRD42023445849:来自 130 份记录的数据提供了 140 名患者的详细信息。93例患者(66.4%)的主要病因是肺结核,36例患者(25.7%)的主要病因是恶性肿瘤,其余11%的病因是其他原因。肺结核患者的平均年龄为 35.7 岁,而恶性肿瘤患者的平均年龄为 55.44 岁。结核病症状主要包括发热、头痛和感觉改变,而恶性肿瘤病例通常表现为进行性脑病、头痛和特定的神经功能缺损。中枢神经系统结核的明显指标是脉络膜小结和矛盾反应。此外,63 名结核病患者出现肺部粟粒状阴影,49 名患者的脑脊液检查结果异常。恶性肿瘤组中,13 名患者出现肺部绒毛状病变,8 名患者出现 CSF 异常。就结果而言,恶性肿瘤组的死亡率为 58.3%,而结核病组为 10.8%,其他病例为 27.3%,死亡率差异显著:结论:脑睫状肌病变是一种重要的影像学异常,需要及时进行检查。在免疫功能低下的状态下,脑部睫状体病变的诊断方法更加多样,往往会带来更大的挑战。

Purpose: Although stent-assisted technique is expected to help provide a scaffold for neointima formation at the orifice of the aneurysm, not all aneurysms treated with stent-assisted technique develop complete neointima formation. The white-collar sign (WCS) indicates neointimal tissue formation at the aneurysm neck that prevents aneurysm recanalization. The aim of this study was to explore factors related to WCS appearance after stent-assisted coil embolization of unruptured intracranial aneurysms (UIAs).

Methods: A total of 59 UIAs treated with a Neuroform Atlas stent were retrospectively analyzed. The WCS was identified on digital subtraction angiography (DSA) 1 year after coil embolization. The cohort was divided into WCS-positive and WCS-negative groups, and possible predictors of the WCS were explored using logistic regression analysis.

Results: The WCS appeared in 20 aneurysms (33.9%). In the WCS-positive group, neck size was significantly smaller (4.2 (interquartile range (IQR): 3.8-4.6) versus 5.4 (IQR: 4.2-6.8) mm, p = .006), the VER was significantly higher (31.8% (IQR: 28.6%-38.4%) versus 27.6% (IQR: 23.6%-33.8%), p = .02), and the rate of RROC class 1 immediately after treatment was significantly higher (70% vs 20.5%, p < .001) than in the WCS-negative group. On multivariate analysis, neck size (odds ratio (OR): 0.542, 95% confidence interval (CI): 0.308-0.954; p = .03) and RROC class 1 immediately after treatment (OR: 6.99, 95% CI: 1.769-27.55; p = .006) were independent predictors of WCS appearance.

Conclusions: Smaller neck size and complete occlusion immediately after treatment were significant factors related to WCS appearance in stent-assisted coil embolization for UIAs using the Neuroform Atlas stent.

目的:虽然支架辅助技术有望为动脉瘤口处的新生内膜形成提供支架,但并非所有采用支架辅助技术治疗的动脉瘤都能形成完整的新生内膜。白领征(WCS)表示动脉瘤颈部的新生内膜组织形成,阻碍了动脉瘤的再通畅。本研究旨在探讨支架辅助线圈栓塞治疗未破裂颅内动脉瘤(UIA)后出现 WCS 的相关因素:回顾性分析了59例使用Neuroform Atlas支架治疗的颅内动脉瘤。线圈栓塞1年后,通过数字减影血管造影(DSA)确定了WCS。研究组被分为WCS阳性组和WCS阴性组,并使用逻辑回归分析探讨了WCS的可能预测因素:结果:20 个动脉瘤出现了 WCS(33.9%)。在 WCS 阳性组中,动脉瘤颈尺寸明显较小(4.2(四分位间距 (IQR):3.8-4.6)mm 对 5.4(IQR:4.2-6.8)mm,P = .006),VER 明显较高(31.8%(IQR:28.6%-38.4%)对 27.6%(IQR:23.6%-33.8%),p = .02),治疗后立即出现 RROC 1 级的比例明显高于 WCS 阴性组(70% 对 20.5%,p < .001)。在多变量分析中,颈部大小(几率比(OR):0.542,95% 置信区间(CI):0.308-0.954;P = .03)和治疗后立即出现 RROC 1 级(OR:6.99,95% CI:1.769-27.55;P = .006)是出现 WCS 的独立预测因素:结论:在使用 Neuroform Atlas 支架辅助线圈栓塞治疗 UIA 的过程中,颈部较小和治疗后立即完全闭塞是出现 WCS 的重要相关因素。

Histopathological examination of characteristic brain MRI findings in acute hyperammonemic encephalopathy: A case report and review of the literature. 急性高氨血症性脑病特征性脑MRI表现的组织病理学检查:一例报告和文献复习。
IF 1.3 Q4 NEUROIMAGING Pub Date : 2024-10-01 Epub Date: 2023-11-01 DOI: 10.1177/19714009231212370

Introduction: Acute hyperammonemic encephalopathy is associated with distinct brain MRI findings, namely, hyperintensity in T2-weighted sequences as well as restricted diffusion in diffusion-weighted imaging with accentuation in the insular cortex and cingulate gyrus. The pathophysiology and the histopathological correlates of these characteristic MRI findings are largely unknown.

Case report: We present a 57-year-old male with a history of chronic alcohol abuse, liver cirrhosis and portal hypertension, and a clinical syndrome (variceal bleeding, depression of consciousness, seizures), elevated plasma ammonia levels, and characteristic brain MRI abnormalities suggestive of acute hyperammonemic encephalopathy. A postmortem histopathological examination revealed extensive hypoxic ischemic encephalopathy without evidence for metabolic encephalopathy. No episodes of prolonged cerebral hypoxemia were documented throughout the course of the disease. We conducted a review of the literature, which exhibited no reports of hyperammonemic encephalopathy in association with characteristic brain MRI findings and a consecutive histopathological examination.

Conclusion: This is the first report of a patient with acute hyperammonemic encephalopathy together with characteristic brain MRI findings and a histopathological correlation. Although characteristic MRI findings of acute hyperammonemic encephalopathy were present, a histopathological examination revealed only hypoxic pathology without signs of metabolic encephalopathy.

引言:急性高氨血症性脑病与不同的脑MRI表现有关,即T2加权序列中的高信号,以及弥散加权成像中的限制性扩散,岛皮质和扣带回加重。这些特征性MRI表现的病理生理学和组织病理学相关性在很大程度上是未知的。病例报告:我们报告一名57岁男性,有慢性酗酒、肝硬化和门静脉高压病史,有临床综合征(静脉曲张出血、意识障碍、癫痫发作)、血浆氨水平升高和特征性脑MRI异常,提示急性高氨血症性脑病。尸检组织病理学检查显示广泛的缺氧缺血性脑病,没有代谢性脑病的证据。在整个疾病过程中,没有记录到长期脑低氧血症的发作。我们对文献进行了回顾,这些文献没有显示与特征性脑MRI检查和连续的组织病理学检查相关的高氨血症性脑病的报告。结论:这是第一例急性高氨血症性脑病患者的报告,同时伴有特征性脑MRI表现和组织病理学相关性。尽管存在急性高氨血症脑病的特征性MRI表现,但组织病理学检查仅显示缺氧病理,没有代谢性脑病的迹象。

Partial ectopic posterior pituitary: A rare imaging entity with literature review. 垂体后叶部分异位:一种罕见的影像学实体并文献复习。
IF 1.3 Q4 NEUROIMAGING Pub Date : 2024-10-01 Epub Date: 2023-11-03 DOI: 10.1177/19714009231212369

Abnormal development of the posterior pituitary gland can lead to an ectopic location of the neurohypophysis, commonly seen at the median eminence of the hypothalamus or along the infundibular stalk. A partial ectopic posterior pituitary (PEPP) is a very rare variant of the ectopic posterior pituitary, defined as the presence of a double bright spot of neurohypophysis seen in both orthotopic and ectopic locations. We report a two-year-old male toddler with bilateral optic nerve hypoplasia and severe visual impairment who presented to the endocrine outpatient clinic for hypopituitarism evaluation. Magnetic resonance imaging (MRI) of the brain revealed a hypoplastic pituitary gland and infundibulum with a double bright spot of neurohypophysis in the expected normal location and along the median eminence. Severe hypoplasia of both optic nerves and the optic chiasm was also seen. Septum pellucidum was present with no evidence of other brain malformations. The findings are in the septo-optic dysplasia spectrum associated with hypothalamic-pituitary dysfunction and a very rare entity called PEPP. To our knowledge, only a handful of reported cases of this rare entity exist in the literature.

垂体后叶发育异常可导致神经垂体异位,常见于下丘脑正中隆起或漏斗柄。垂体后叶部分异位(PEPP)是垂体后叶异位的一种非常罕见的变体,其定义为在原位和异位位置都存在神经垂体的双亮点。我们报告了一名患有双侧视神经发育不全和严重视觉障碍的两岁男性幼儿,他在内分泌门诊接受垂体发育不全评估。大脑磁共振成像(MRI)显示垂体和漏斗发育不全,在预期正常位置和正中隆起处有神经垂体双亮点。视神经和视交叉严重发育不全。透明隔存在,没有其他大脑畸形的证据。这些发现属于视隔发育不良谱系,与下丘脑-垂体功能障碍和一种非常罕见的称为PEPP的实体有关。据我们所知,文献中只存在少数这种罕见实体的报告病例。

Introduction: Carotid artery stenting (CAS) through transradial access (TRA) is emerging as an alternative to carotid endarterectomy. However, the current evidence base is limited, mainly comprising single-center studies.

Objective: This systematic review and meta-analysis aim to assess the safety and effectiveness of TRA for CAS, providing evidence to support clinical decisions.

Methods: We conducted searches on PUBMED, Cochrane Library, Embase, and Web of Science databases, including studies on TRA for CAS. Studies with fewer than 20 patients, non-primary outcomes, and non-full-text articles were excluded.

Results: We analyzed 14 studies involving 1,166 patients who underwent CAS via TRA. Procedural success rate was high in 13 studies, with a 95% rate (95% CI; 92%-98%). Crossover to TFA access was observed in 12 studies at 6% (95% CI: 3%-9%). Transradial access failure was reported in four studies, with a rate of 0% (95% CI: 0%-0%). Cannulation failure resulted in a rate of 4% (95% CI: 2%-7%). Asymptomatic radial artery occlusion (ARAO) occurred at a rate of 2% based on eight studies (95% CI: 0%-5%). Forearm hematoma was reported in 10 studies, with an occurrence of 1% (95% CI: 0%-2%). Cerebral vascular attacks (CAV) within 30 days were assessed in 13 studies, indicating a 2% occurrence (95% CI: 1%-2%).

Conclusion: The findings suggest that TRA for CAS yields promising outcomes with high success rates and low complication rates. Further research should focus on randomized controlled trials and long-term outcomes to validate and extend findings.

导言:通过经桡动脉入路(TRA)进行颈动脉支架植入术(CAS)正在成为颈动脉内膜剥脱术的替代方法。然而,目前的证据基础有限,主要包括单中心研究:本系统综述和荟萃分析旨在评估 TRA 用于 CAS 的安全性和有效性,为临床决策提供证据支持:我们在 PUBMED、Cochrane Library、Embase 和 Web of Science 数据库中进行了检索,包括有关 TRA 治疗 CAS 的研究。结果:我们分析了 14 项研究,涉及 1,000 名患者:我们分析了 14 项研究,涉及 1,166 名通过 TRA 接受 CAS 的患者。13项研究的手术成功率很高,达到95%(95% CI;92%-98%)。有 12 项研究观察到经桡动脉入路的交叉率为 6%(95% CI:3%-9%)。有四项研究报告经桡动脉入路失败,失败率为 0% (95% CI: 0%-0%)。插管失败率为 4%(95% CI:2%-7%)。根据 8 项研究,无症状桡动脉闭塞 (ARAO) 发生率为 2%(95% CI:0%-5%)。10项研究报告了前臂血肿,发生率为1%(95% CI:0%-2%)。13项研究对30天内的脑血管病发作(CAV)进行了评估,结果显示发生率为2%(95% CI:1%-2%):研究结果表明,CAS 的 TRA 具有成功率高、并发症发生率低的良好效果。进一步的研究应侧重于随机对照试验和长期结果,以验证和扩展研究结果。

Transradial access for the endovascular treatment of intracranial aneurysms using the Woven EndoBridge device: A systematic review and pooled analysis. 使用 Woven EndoBridge 装置经桡动脉进入血管内治疗颅内动脉瘤:系统回顾和汇总分析。
IF 1.3 Q4 NEUROIMAGING Pub Date : 2024-10-01 Epub Date: 2024-03-19 DOI: 10.1177/19714009241240328

Background: The Woven EndoBridge (WEB) device is a minimally invasive endovascular treatment option for patients with cerebral aneurysms. Transradial access (TRA) is a technique that involves accessing the arterial system through the radial artery in the wrist rather than the femoral artery in the groin. Several studies have investigated the use of TRA for WEB device deployment in treating intracranial aneurysms.

Methods: A systematic review was conducted to evaluate the TRA for WEB device deployment in treating intracranial aneurysms. The databases PubMed, Cochrane, Embase, Scopus, and Web of Science were searched. To reduce the risk of bias, this systematic review only included studies reporting on using TRA in WEB device deployment for intracranial aneurysm treatment with a minimum of four patients.

Results: In this systematic review, 186 patients were included across five studies, with TRA used in 183 cases analyzed. The study population had a higher proportion of females (n = 118%-69%) than males, with a mean age of 62 years old. Among the aneurysms treated, 46 were ruptured, and 119 were located at bifurcation sites, with a mean maximum diameter/width of 6.6 mm and mean height of 5.9 mm. Adjunctive coiling was used in three cases, and adjunctive stenting was used in nine cases. In two cases, conversion to a femoral artery access was necessary.

Conclusion: The available results suggest TRA with the WEB device is a safe and effective alternative. However, using TRA versus TFA should be individualized based on patient factors and operator experience.

背景:编织内桥(WEB)装置是脑动脉瘤患者的一种微创血管内治疗选择。经桡动脉入路(TRA)是一种通过手腕桡动脉而非腹股沟股动脉进入动脉系统的技术。有几项研究调查了经桡动脉入路技术在治疗颅内动脉瘤的 WEB 装置部署中的应用:方法:我们进行了一项系统性回顾,以评估在治疗颅内动脉瘤时使用 TRA 部署 WEB 装置的情况。检索了 PubMed、Cochrane、Embase、Scopus 和 Web of Science 等数据库。为减少偏倚风险,本系统综述仅纳入了至少有四名患者的关于使用 TRA 部署 WEB 装置治疗颅内动脉瘤的研究:本系统综述共纳入了五项研究中的 186 例患者,其中 183 例分析中使用了 TRA。研究人群中女性比例(n = 118%-69%)高于男性,平均年龄为 62 岁。在接受治疗的动脉瘤中,46个破裂,119个位于分叉部位,平均最大直径/宽度为6.6毫米,平均高度为5.9毫米。有三例使用了辅助卷曲术,九例使用了辅助支架术。有两个病例需要转为股动脉入路:现有结果表明,使用 WEB 设备进行 TRA 是一种安全有效的替代方法。结论:现有结果表明,使用 WEB 设备进行 TRA 是一种安全有效的替代方法。然而,使用 TRA 与 TFA 相比,应根据患者因素和操作者经验进行个体化选择。
