Background: Orificial tuberculosis is a rare type of tuberculosis, which is easy to be misdiagnosed, and can cause great damage to the perianal skin and mucosa. Early diagnosis can avoid further erosion of the perianal muscle tissue by tuberculosis bacteria.

Case summary: Here, we report a case of disseminated tuberculosis in a 62-year-old male patient with a perianal tuberculous ulcer and active pulmonary tuberculosis, intestinal tuberculosis and orificial tuberculosis. This is an extremely rare case of cutaneous tuberculosis of the anus, which was misdiagnosed for nearly a year. The patient received conventional treatment in other medical institutions, but specific treatment was delayed. Ultimately, proper diagnosis and treatment with standard anti-tuberculosis drugs for one year led to complete cure.

Conclusion: For skin ulcers that do not heal with repeated conventional treatments, consider ulcers caused by rare bacteria, such as Mycobacterium tuberculosis.

背景:人工肛门结核是一种罕见的结核病,容易被误诊,对肛周皮肤和粘膜的损害很大。病例摘要:这里,我们报告了一例 62 岁男性患者的播散性结核病例,患者患有肛周结核性溃疡和活动性肺结核、肠结核及人工结核。这是一个极其罕见的肛门皮肤结核病例,被误诊近一年。患者在其他医疗机构接受了常规治疗,但特异性治疗被延误。最终,经过正确诊断和一年的标准抗结核药物治疗,患者完全治愈:对于反复接受常规治疗仍不愈合的皮肤溃疡,应考虑由结核分枝杆菌等罕见细菌引起的溃疡。

Background: Postoperative aortobronchial fistula (ABF) is a rare complication that can occur in 0.3%-5.0% of patients over an extended period of time after thoracic aortic surgery. Direct visualization of the fistula via imaging is rare.

Aim: To investigate the relationship between computed tomography (CT) findings and the clinical signs/symptoms of ABF after thoracic aortic surgery.

Methods: Six patients (mean age 71 years, including 4 men and 2 women) with suspected ABF on CT (air around the graft) at our hospital were included in this retrospective study between January 2004 and September 2022. Chest CT findings included direct confirmation of ABF, peri-graft fluid, ring enhancement, dirty fat sign, atelectasis, pulmonary hemorrhage, and bronchodilation, and the clinical course were retrospectively reviewed. The proportion of each type of CT finding was calculated.

Results: ABF detection after surgery was found to have a mean and median of 14 and 13 years, respectively. Initial signs and symptoms were asymptomatic in 4 patients, bloody sputum was found in 1 patient, and fever was present in 1 patient. The complications of ABF included graft infection in 2 patients and graft infection with hemoptysis in 2 patients. Of the 6 patients, 3 survived, 2 died, and 1 was lost to follow-up. The locations of the ABFs were as follows: 1 in the ascending aorta; 1 in the aortic arch; 2 in the aortic arch leading to the descending aorta; and 2 in the descending aorta. ABFs were directly confirmed by CT in 4/6 (67%) patients. Peri-graft dirty fat (4/6, 67%) and peri-graft ring enhancement (3/6, 50%) were associated with graft infection, endoleaks and pseudoaneurysms were associated with hemoptysis (2/6, 33%).

Conclusion: Asymptomatic ABF after thoracic aortic surgery can be confirmed on chest CT. CT is useful for the diagnosis of ABF and its complications.

背景:术后主动脉支气管瘘(ABF)是一种罕见的并发症,0.3%-5.0%的患者会在胸主动脉手术后较长时间内出现这种情况。目的:研究胸主动脉手术后计算机断层扫描(CT)结果与 ABF 临床症状/体征之间的关系:2004年1月至2022年9月期间,本院共收治了6例CT检查疑似ABF(移植物周围有空气)的患者(平均年龄71岁,包括4名男性和2名女性),并进行了回顾性研究。胸部 CT 结果包括直接确认 ABF、移植物周围积液、环状强化、脏脂肪征、肺不张、肺出血和支气管扩张,并对临床病程进行了回顾性回顾。计算了各类 CT 发现的比例:结果:术后发现 ABF 的平均年龄和中位数分别为 14 年和 13 年。4 名患者最初无症状,1 名患者发现血痰,1 名患者出现发热。ABF 的并发症包括 2 名患者的移植物感染和 2 名患者的移植物感染并咯血。6 名患者中,3 人存活,2 人死亡,1 人失去随访机会。ABF 的位置如下:1 例位于升主动脉;1 例位于主动脉弓;2 例位于通往降主动脉的主动脉弓;2 例位于降主动脉。4/6(67%)的患者通过 CT 直接确认了 ABF。移植物周围脏污脂肪(4/6,67%)和移植物周围环状强化(3/6,50%)与移植物感染有关,内漏和假性动脉瘤与咯血(2/6,33%)有关:结论:胸部主动脉手术后无症状的ABF可通过胸部CT确诊。结论:胸部 CT 可确诊胸主动脉手术后无症状的 ABF。

Background: With the increasingly extensive application of artificial intelligence (AI) in medical systems, the accuracy of AI in medical diagnosis in the real world deserves attention and objective evaluation.

Aim: To investigate the accuracy of AI diagnostic software (Shukun) in assessing ischemic penumbra/core infarction in acute ischemic stroke patients due to large vessel occlusion.

Methods: From November 2021 to March 2022, consecutive acute stroke patients with large vessel occlusion who underwent mechanical thrombectomy (MT) post-Shukun AI penumbra assessment were included. Computed tomography angiography (CTA) and perfusion exams were analyzed by AI, reviewed by senior neurointerventional experts. In the case of divergences among the three experts, discussions were held to reach a final conclusion. When the results of AI were inconsistent with the neurointerventional experts' diagnosis, the diagnosis by AI was considered inaccurate.

Results: A total of 22 patients were included in the study. The vascular recanalization rate was 90.9%, and 63.6% of patients had modified Rankin scale scores of 0-2 at the 3-month follow-up. The computed tomography (CT) perfusion diagnosis by Shukun (AI) was confirmed to be invalid in 3 patients (inaccuracy rate: 13.6%).

Conclusion: AI (Shukun) has limits in assessing ischemic penumbra. Integrating clinical and imaging data (CT, CTA, and even magnetic resonance imaging) is crucial for MT decision-making.

背景:目的:研究人工智能诊断软件(Shukun)对大血管闭塞所致急性缺血性卒中患者缺血性半影/核心梗死评估的准确性:方法:纳入2021年11月至2022年3月期间连续接受舒坤人工智能半影评估后机械取栓术(MT)的大血管闭塞急性脑卒中患者。计算机断层扫描血管造影(CTA)和灌注检查由人工智能进行分析,并由资深神经介入专家进行审查。如果三位专家意见不一致,则进行讨论以得出最终结论。如果人工智能的结果与神经介入专家的诊断不一致,则认为人工智能的诊断不准确:研究共纳入了 22 名患者。血管再通率为 90.9%,在 3 个月的随访中,63.6% 的患者改良兰金量表评分为 0-2。3名患者的计算机断层扫描(CT)灌注诊断被证实无效(不准确率:13.6%):结论:AI(Shukun)在评估缺血半影方面存在局限性。整合临床和成像数据(CT、CTA 甚至磁共振成像)对于 MT 决策至关重要。

Background: Lung abscess found on chest X-ray and computed tomography examinations is rare in infants and young children. Several pathogens can cause lung abscesses, with the most common pathogens being anaerobes, Streptococci and Staphylococcus aureus. Streptococcus pseudopneumoniae (S. pseudopneumoniae) is a member of the Streptococcaceae family, and is mainly isolated from respiratory tract specimens. There are currently no cases of lung abscess caused by S. pseudopneumoniae in the literature.

Case summary: A 2-year-old boy was admitted to hospital due to persistent cough and fever. Lung computed tomography examination suggested the formation of a lung abscess. His diagnosis was not confirmed by testing for serum respiratory pathogens (6 items), respiratory pathogen nucleic acid (27 items), and laboratory culture. Finally, metagenomic next-generation sequencing of bronchoalveolar lavage fluid revealed the presence of S. pseudopneumoniae, confirming its role in causing the lung abscess. After receiving antibiotic treatment, reexamination with lung computed tomography showed that the abscess was resorbed and the patient's outcome was good.

Conclusion: This is the first report of a lung abscess in a child caused by S. pseudopneumoniae infection. Metagenomic next-generation sequencing of bronchoalveolar lavage fluid is helpful in achieving rapid and accurate pathogen identification.

背景:胸部 X 光和计算机断层扫描检查发现的肺脓肿在婴幼儿中很少见。多种病原体可导致肺脓肿,最常见的病原体是厌氧菌、链球菌和金黄色葡萄球菌。假肺炎链球菌(S. pseudopneumoniae)属于链球菌科,主要从呼吸道标本中分离出来。病例摘要:一名两岁男孩因持续咳嗽和发烧入院。肺部计算机断层扫描检查显示有肺脓肿形成。通过检测血清呼吸道病原体(6 项)、呼吸道病原体核酸(27 项)和实验室培养,均未确诊。最后,支气管肺泡灌洗液的元基因组下一代测序发现了假肺炎双球菌,证实了它是导致肺脓肿的罪魁祸首。接受抗生素治疗后,肺部计算机断层扫描复查显示脓肿已吸收,患者预后良好:这是首例由假肺炎双球菌感染导致儿童肺脓肿的报告。支气管肺泡灌洗液的元基因组下一代测序有助于快速准确地鉴定病原体。

Jaw and maxillofacial bone lesions encompass a wide variety of both neoplastic and non-neoplastic pathologies. These lesions can arise from various tissues, including bone, cartilage, and soft tissue, each presenting distinct challenges in diagnosis and treatment. While some pathologies exhibit characteristic imaging features that aid in diagnosis, many others are nonspecific. This overlap often necessitates a multimodal imaging approach, combining techniques such as radiographs, computed tomography, and magnetic resonance imaging to achieve a diagnosis or narrow the diagnostic considerations. This article provides a comprehensive review of the imaging approach to jaw and maxillofacial bone tumors, including updates on the 2022 World Health Organization classification of these tumors. The relevant anatomy of the jaw and dental structures that is important for accurate imaging interpretation is discussed.

颌骨和颌面部骨病变包括各种肿瘤性和非肿瘤性病变。这些病变可能来自不同的组织,包括骨、软骨和软组织,每种病变都给诊断和治疗带来不同的挑战。有些病变表现出有助于诊断的特征性影像学特征,而其他许多病变则没有特异性。这种重叠往往需要采用多模态成像方法,结合射线照相、计算机断层扫描和磁共振成像等技术来实现诊断或缩小诊断范围。本文全面回顾了颌骨和颌面部骨肿瘤的成像方法,包括世界卫生组织 2022 年对这些肿瘤分类的最新进展。文章还讨论了颌骨和牙齿结构的相关解剖学知识,这些知识对于准确的成像解读非常重要。

Background: Minimally invasive surgery (MIS) and craniotomy (CI) are the current treatments for spontaneous supratentorial cerebral haemorrhage (SSTICH).

Aim: To compare the efficacy and safety of MIS and CI for the treatment of SSTICH.

Methods: Clinical and imaging data of 557 consecutive patients with SSTICH who underwent MIS or CI between January 2017 and December 2022 were retrospectively analysed. The patients were divided into two subgroups: The MIS group and CI group. Propensity score matching was performed to minimise case selection bias. The primary outcome was a dichotomous prognostic (favourable or unfavourable) outcome based on the modified Rankin Scale (mRS) score at 3 months; an mRS score of 0-2 was considered favourable.

Results: In both conventional statistical and binary logistic regression analyses, the MIS group had a better outcome. The outcome of propensity score matching was unexpected (odds ratio: 0.582; 95%CI: 0.281-1.204; P = 0.144), which indicated that, after excluding the interference of each confounder, different surgical modalities were more effective, and there was no significant difference in their prognosis.

Conclusion: Deciding between MIS and CI should be made based on the individual patient, considering the hematoma size, degree of midline shift, cerebral swelling, and preoperative Glasgow Coma Scale score.

背景:目的:比较微创手术(MIS)和开颅手术(CI)治疗SSTICH的有效性和安全性:回顾性分析2017年1月至2022年12月期间接受MIS或CI治疗的557例连续SSTICH患者的临床和影像学数据。患者被分为两个亚组:MIS组和CI组。为尽量减少病例选择偏倚,进行了倾向评分匹配。主要结果是根据3个月时的改良Rankin量表(mRS)评分得出的二分法预后结果(有利或不利);mRS评分为0-2分为有利:在传统统计分析和二元逻辑回归分析中,MIS 组的预后更好。倾向得分匹配的结果出乎意料(几率比:0.582;95%CI:0.281-1.204;P = 0.144),这表明在排除了各种混杂因素的干扰后,不同手术方式的疗效更佳,而其预后并无显著差异:结论:应根据患者的个体情况,考虑血肿大小、中线移位程度、脑肿胀和术前格拉斯哥昏迷量表评分,决定采用 MIS 还是 CI。

Background: The rare co-occurrence of oligodendroglioma and arteriovenous malformation (AVM) in the same intracranial location.

Case summary: In a 61-year-old man presenting with progressive headaches, is described in this case study. Preoperative multimodal imaging techniques (computed tomography, magnetic resonance imaging, magnetic resonance spectroscopy, digital subtraction angiography, and computed tomography angiography) were employed to detect hemorrhage, cystic and solid lesions, and arteriovenous shunting in the right temporal lobe. The patient underwent right temporal craniotomy for lesion removal, and postoperative pathological analysis confirmed the presence of oligodendroglioma (World Health Organization grade II, not otherwise specified) and AVM.

Conclusion: The preoperative utilization of multimodal imaging examination can help clinicians reduce the likelihood of misdiagnosis or oversight of these conditions, and provides important information for subsequent treatment. This case supports the feasibility of craniotomy for the removal of glioma with AVM.

背景:少突胶质细胞瘤和动静脉畸形(AVM)同时发生在同一颅内位置的病例十分罕见。病例摘要:本病例研究描述了一名61岁的男性,他出现进行性头痛。术前采用多模态成像技术(计算机断层扫描、磁共振成像、磁共振波谱、数字减影血管造影和计算机断层扫描血管造影)检测右颞叶的出血、囊性和实性病变以及动静脉分流。患者接受了右颞部开颅手术切除病灶,术后病理分析证实了少突胶质细胞瘤(世界卫生组织II级,未另作说明)和动静脉畸形的存在:结论:术前利用多模态成像检查可帮助临床医生减少误诊或漏诊的可能性,并为后续治疗提供重要信息。本病例证实了开颅手术切除伴有 AVM 的胶质瘤的可行性。

Plea to radiologists: Please consider Mahvash disease when encountering an enlarged pancreas. 恳请放射科医生当遇到胰腺肿大时,请考虑马赫瓦什病。
IF 1.4 Q3 RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING Pub Date : 2024-08-28 DOI: 10.4329/wjr.v16.i8.371

Radiologists play a key role in establishing an early and accurate diagnosis, especially for rare diseases. Mahvash disease (OMIM 619290) is an autosomal recessive hereditary disease caused by inactivating mutations of the glucagon receptor and its main clinical consequences are pancreatic neuroendocrine tumors and in some cases, porto-sinusoidal vascular disease and portal hypertension. Untreated Mahvash disease can be lethal. The diagnosis of Mahvash disease has almost always been delayed in the past due to radiologists' unawareness of or unfamiliarity with the unique imaging features of Mahvash disease which are moderately to enormously enlarge pancreas with preserved pancreas contour and parenchyma without vascular involvement or lymphadenopathy. These features help differentiate Mahvash disease from other etiologies of diffusely enlarged pancreas such as diffuse pancreatic ductal carcinoma, diffuse pancreatic lymphoma, and autoimmune pancreatitis. Invoking Mahvash disease in the differential diagnosis of an enlarged pancreas has recently been shown to facilitate early diagnosis. To prevent missing the diagnosis of this significant disease, I sincerely ask radiologists to consider Mahvash disease in their differential diagnoses of diffusely enlarged pancreas.

放射科医生在确定早期准确诊断,尤其是罕见疾病的诊断方面发挥着关键作用。马赫瓦什病(OMIM 619290)是一种常染色体隐性遗传病,由胰高血糖素受体的失活突变引起,其主要临床后果是胰腺神经内分泌肿瘤,在某些情况下还会导致门静脉血管疾病和门静脉高压症。未经治疗的马赫瓦什病可导致死亡。过去,由于放射科医生不了解或不熟悉马瓦什病的独特影像学特征,马瓦什病的诊断几乎总是被延误。马瓦什病的影像学特征是胰腺中度至巨型增大,胰腺轮廓和实质保留,无血管受累或淋巴结病变。这些特征有助于将马赫瓦什病与弥漫性胰腺导管癌、弥漫性胰腺淋巴瘤和自身免疫性胰腺炎等其他病因引起的弥漫性胰腺肿大区分开来。最近的研究表明,在胰腺肿大的鉴别诊断中考虑马瓦什病有助于早期诊断。为了防止漏诊这一重大疾病,我真诚地请求放射科医生在鉴别诊断弥漫性胰腺肿大时考虑马瓦什病。

BACKGROUND After approval for clinical use in 2017, early investigations of ultra-high-field abdominal magnetic resonance imaging (MRI) have demonstrated its feasibility as well as diagnostic capabilities in neuroimaging. However, there are no to few systematic reviews covering the entirety of its neurosurgical applications as well as the trends in the literature with regard to the aforementioned application. AIM To assess the impact of 7-Tesla MRI (7T MRI) on neurosurgery, focusing on its applications in diagnosis, treatment planning, and postoperative assessment, and to systematically analyze and identify patterns and trends in the existing literature related to the utilization of 7T MRI in neurosurgical contexts. METHODS A systematic search of PubMed was conducted for studies published between January 1, 2017, and December 31, 2023, using MeSH terms related to 7T MRI and neurosurgery. The inclusion criteria were: Studies involving patients of all ages, meta-analyses, systematic reviews, and original research. The exclusion criteria were: Pre-prints, studies with insufficient data (e.g. , case reports and letters), non-English publications, and studies involving animal subjects. Data synthesis involved standardized extraction forms, and a narrative synthesis was performed. RESULTS We identified 219 records from PubMed within our defined period, with no duplicates or exclusions before screening. After screening, 125 articles were excluded for not meeting inclusion criteria, leaving 94 reports. Of these, 2 were irrelevant to neurosurgery and 7 were animal studies, resulting in 85 studies included in our systematic review. Data were categorized by neurosurgical procedures and diseases treated using 7T MRI. We also analyzed publications by country and the number of 7T MRI facilities per country was also presented. Experimental studies were classified into comparison and non-comparison studies based on whether 7T MRI was compared to lower field strengths. CONCLUSION 7T MRI holds great potential in improving the characterization and understanding of various neurological and psychiatric conditions that may be neurosurgically treated. These include epilepsy, pituitary adenoma, Parkinson's disease, cerebrovascular diseases, trigeminal neuralgia, traumatic head injury, multiple sclerosis, glioma, and psychiatric disorders. Superiority of 7T MRI over lower field strengths was demonstrated in terms of image quality, lesion detection, and tissue characterization. Findings suggest the need for accelerated global distribution of 7T magnetic resonance systems and increased training for radiologists to ensure safe and effective integration into routine clinical practice.
背景超高场腹部磁共振成像(MRI)于 2017 年获准用于临床后,其早期研究已证明了其可行性以及在神经成像方面的诊断能力。然而,目前还没有或很少有系统性综述涵盖其神经外科应用的全部内容,以及有关上述应用的文献趋势。目的 评估 7-Tesla MRI(7T 磁共振成像)对神经外科的影响,重点关注其在诊断、治疗计划和术后评估中的应用,并系统分析和识别现有文献中与神经外科中 7T 磁共振成像应用相关的模式和趋势。方法 使用与 7T MRI 和神经外科相关的 MeSH 术语对 PubMed 上 2017 年 1 月 1 日至 2023 年 12 月 31 日期间发表的研究进行了系统检索。纳入标准为涉及所有年龄段患者的研究、荟萃分析、系统综述和原创研究。排除标准为预印本、数据不充分的研究(如病例报告和信件)、非英语出版物以及涉及动物的研究。数据综合采用标准提取表,并进行了叙述性综合。结果 我们在规定时间内从 PubMed 上找到了 219 条记录,筛选前无重复或排除。经过筛选,125 篇文章因不符合纳入标准而被排除,剩下 94 篇报告。其中,2 篇与神经外科无关,7 篇为动物实验,最终有 85 篇研究纳入了我们的系统综述。我们按照神经外科手术和使用 7T MRI 治疗的疾病对数据进行了分类。我们还按国家对论文进行了分析,并列出了每个国家的 7T MRI 设备数量。根据 7T 磁共振成像是否与较低场强进行比较,将实验研究分为比较研究和非比较研究。结论 7T 磁共振成像在改善各种神经和精神疾病的特征描述和理解方面具有巨大的潜力,这些疾病可能需要进行神经外科治疗。这些疾病包括癫痫、垂体腺瘤、帕金森病、脑血管疾病、三叉神经痛、头部外伤、多发性硬化、胶质瘤和精神疾病。7T 磁共振成像在图像质量、病变检测和组织特征描述方面均优于较低磁场强度。研究结果表明,有必要加快 7T 磁共振系统在全球的推广,并加强对放射科医生的培训,以确保安全有效地将其纳入常规临床实践。

Lymphoscintigraphy is a nuclear medicine procedure that uses a small quantity of radioactive particles for visualizing the lymphatic system. Traditionally, the radiotracer was injected subcutaneously, but the quality of lymphatic path imaging was scarce due to high background. Intradermal radiotracer injection is considered the modern-day intralymphatic injection. We propose rest/stress intradermal lymphoscintigraphy for the diagnosis, staging and surgical planning of lymphedema. Major and minor findings were described in primary and secondary lymphedema. Based on the in-depth information of the lymphatic pathways, physiotherapists and microsurgeons can obtain important functional information in patients’ selection to treat with physical treatments and/or undergo microsurgery.
淋巴管造影(Lymphoscintigraphy)是一种利用少量放射性粒子观察淋巴系统的核医学方法。传统的做法是皮下注射放射性示踪剂,但由于本底较高,淋巴路径成像质量不高。皮内放射性示踪剂注射被认为是现代的淋巴内注射。我们建议将静息/应激皮内淋巴管造影用于淋巴水肿的诊断、分期和手术规划。我们描述了原发性和继发性淋巴水肿的主要和次要检查结果。基于淋巴通路的深入信息,物理治疗师和显微外科医生可以获得重要的功能信息,帮助患者选择物理治疗和/或显微外科手术。
