Dermoid cysts are rare, benign teratomatous congenital lesions, dermoid cysts originating from the submandibular gland are extremely rare. A 47-year-old female admitted for swelling at the right of the neck with duration of 20years. The neck ultrasonography revealed intense-content, cystic lesion containing minor fatty islets at the localization of right submandibular gland. The computed tomography and magnetic resonance imaging demonstrated a dermoid cyst originating from the submandibular gland. However patient refused surgery. Although dermoid cysts are generally at midline, may also originate from the submandibular gland itself, as is the case in our patient. This case was presented in 27 Turkish National Congress of Radiology, Antalya, Turkey.
皮样囊肿是罕见的,良性畸胎瘤先天性病变,皮样囊肿起源于颌下腺是极其罕见的。47岁女性,因右侧颈部肿胀入院,病程20年。颈部超声检查显示右侧颌下腺位置有高含量囊性病变,含少量脂肪胰岛。计算机断层扫描和磁共振成像显示一个皮样囊肿起源于下颌骨腺。然而病人拒绝手术。虽然皮样囊肿通常位于中线,但也可能起源于颌下腺本身,如本例患者。该病例在土耳其安塔利亚举行的第27届土耳其全国放射学大会上发表。

CASE SUMMARY This is a case of a 26-yr old lady who was diagnosed to have chorio-carcinoma, after she presented with complaints of irregular vaginal bleeding for one year and hemoptysis for five months. This was following a missed abortion one year back for which dilatation and curettage was done elsewhere. There was a history of one previous full term child birth and two abortions previously. Histopathology of the curettage had revealed few atypical cells in necrotic background with mild inflammatory cell infiltration. When she presented to our institute, a complete metastatic work-up including complete blood counts, liver function tests and serum β-HCG level was done. Baseline blood investigations were within normal limits and serum β-HCG levels at admission was 6, 37,000 IU/ml. Figure 1 Figure 1: Chest X-Ray showing “cannon-ball” pulmonary metastasis before chemotherapy. Chest X-Ray was done which showed evidence of pulmonary metastasis (Figure 1) in the form of “cannon-ball metastasis”. Contrast enhanced CT (CECT) chest confirmed the pulmonary metastasis. CECT abdomen had revealed a bulky uterus with 4x3x3.5 cm intense heterogeneously enhancing area and multiple infarcts in both kidneys with presence of a simple cyst. CECT head was normal. According to FIGO risk scoring system, her score was 12 (high risk Gestational trophoblastic neoplasia). Patient was administered EMA-CO chemotherapy i.e. Etoposide, Methotrexate and Actinomycin on Day 1 and 2; Cyclophosphamide and Vincristine on day 8. After 4 cycles of EMA-CO, her β-HCG levels fell down to 2467.49 IU/ml and chest X-Ray too showed significant resolution of metastatic lesions (Figure 2). Figure 2 Figure 2: Chest X-Ray showing post chemotherapy lesion Pulmonary metastasis in Chorio-carcinoma: “Before and After Chemotherapy” 2 of 3 BACKGROUND Pulmonary metastases are common and most frequently occur with tumors that have rich systemic venous drainage. Examples of such metastases include renal cancers, bone sarcomas, chorio-carcinomas, melanomas, testicular teratomas, and thyroid carcinomas. Chest X-Ray is usually the first imaging modality in which the metastases are diagnosed. It is important to recognize these lesions, as it changes the stage of disease and treatment course. In chorio-carcinoma, usually 60% of patients have pulmonary metastasis at presentation, and in 70-100% cases, the pulmonary lesion is detected at autopsy. The presence of pulmonary metastases is a bad prognostic factor that indicates disseminated disease. In chorio-carcinoma, presence of pulmonary metastasis upgrades the lesion to stage III disease and asks for combination multidrug chemotherapy-EMACO. However, chemo-sensitive tumors, such as chorio-carcinoma and testicular teratoma, have a better prognosis. Tumor may manifest in lungs as pulmonary nodules as in Figure 1. Pulmonary nodules are the most common manifestation of secondary neoplastic disease in the lungs. They are usually derived from tumor emboli that aris
病例总结:这是一个26岁的女性,在她提出一年不规则阴道出血和五个月咯血的主诉后,被诊断为绒毛膜癌。这是在一年前的一次流产后发生的,那次流产是在其他地方进行的扩张和刮宫。以前有过一次足月分娩和两次流产的历史。刮除的组织病理学显示坏死背景中有少量非典型细胞伴轻度炎症细胞浸润。当她来到我们研究所时,我们做了一个完整的转移性检查,包括全血细胞计数、肝功能检查和血清β-HCG水平。基线血液检查在正常范围内,入院时血清β-HCG水平为6,37,000 IU/ml。图1:化疗前胸部x线片示“炮弹状”肺转移。胸部x线检查显示肺转移(图1),表现为“炮弹转移”。胸部增强CT (CECT)证实肺转移。腹部CECT显示子宫体积庞大,面积为4x3x3.5 cm,双肾多发梗死伴单纯性囊肿。CECT头部正常。根据FIGO风险评分系统,患者评分为12分(妊娠滋养细胞瘤高风险)。患者于第1天和第2天给予EMA-CO化疗,即依托泊苷、甲氨蝶呤和放线菌素;第8天使用环磷酰胺和长春新碱。经过4个周期的EMA-CO治疗后,她的β-HCG水平降至2467.49 IU/ml,胸部x线片也显示转移灶的明显消退(图2)。图2:化疗后病变的胸部x线片显示绒毛膜癌的肺转移:“化疗前后”3个中的2个背景肺转移是常见的,最常见于系统性静脉引流丰富的肿瘤。此类转移的例子包括肾癌、骨肉瘤、绒毛膜癌、黑色素瘤、睾丸畸胎瘤和甲状腺癌。胸部x线通常是诊断转移的第一影像学方式。重要的是要认识到这些病变,因为它改变了疾病的阶段和治疗过程。在绒毛膜癌中,通常60%的患者在发病时有肺转移,在70-100%的病例中,尸检时发现肺病变。肺转移的存在是一个不良的预后因素,表明疾病播散。在绒毛膜癌中,肺转移的存在将病变升级为III期疾病,需要联合多药化疗- emaco。然而,对化疗敏感的肿瘤,如绒毛膜癌和睾丸畸胎瘤,预后较好。肿瘤可表现为肺结节,如图1所示。肺结节是肺部继发性肿瘤疾病最常见的表现。它们通常来源于肿瘤栓塞,肿瘤栓塞是由肿瘤毛细血管的侵犯引起的。肿瘤栓子经全身静脉和肺动脉排出,随后停留在小肺动脉或小动脉中,并延伸到邻近的肺组织。化疗可改变这些病变的外观(图2)。完全解决是罕见的。

Pulsatile portal vein sign is an uncommon finding which usually results when the elevated systemic venous pressure is transmitted through the hepatic sinusoids to the portal vein. It is most commonly seen with tricuspid regurgitation and is suggestive of underlying congestive heart failure. CASE REPORT A 34 year old female presented to the medical out patient clinic with complaints of jaundice for 2 weeks duration along with mild distension of abdomen. Past history was significant for a rheumatic valvular heart disease for past 16 years. There was associated history of dyspnoea on exertion and orthopnoea. On examination, the patient had mild hepatomegaly with ascites. The tip of spleen was palpable just below the costal margin. The patient also had a loud pan systolic murmur best heard over the tricuspid area. CBC was unremarkable. The hepatic enzymes and bilirubin were mildly elevated. Viral serologies were negative. Renal functions were normal. The patient was referred for an ultrasound scan to ascertain the cause of deranged hepatic function. Ultrasound scan through the liver revealed coarsened echo texture of liver with surface nodularity suggestive of cirrhosis (Figure-1). Spleen was mildly enlarged. Small amount of ascites was also seen. Doppler imaging of the portal vein revealed presence of pulsatile flow in the portal vein, which dropped below the baseline with each systole (Figure-2). Associated marked enlargement of IVC and hepatic veins was seen (Figure-3) with dilatation of cardiac chambers (right more than left). (Figure-4) Subsequent cardiac echo confirmed presence of multiple valvular diseases with predominant TR.

Figure 4 Figure 4: Grey scale scan at the level of heart showing marked dilatation of the cardiac chambers. DISCUSSION Normal subjects typically demonstrate minimal variation in portal vein velocity on spectral Doppler analysis during breath holding 1 . The mildly phasic pattern is most likely a reflection of changes in transmitted right atrial pressures, with significant dampening by resistance in venules, sinusoids and small portal vein branches. Pulsatile portal venous flow is said to be present when the minimal portal vein flow velocity drops to or below the baseline 2 . Pulsatile portal venous flow is commonly seen with tricuspid regurgitation. In their study of 17 patients, Abu Yousef et al found tricuspid regurgitation in 15 of the 17 patients that were evaluated 2 . Most common cause of tricuspid regurgitation is dilatation of right ventricle due to left ventricular failu
门静脉搏动征象是一种罕见的征象,通常是由于全身静脉压升高通过肝窦传导到门静脉。它最常见于三尖瓣反流,提示潜在的充血性心力衰竭。病例报告一名34岁女性,以黄疸伴腹部轻度肿胀2周就诊于内科门诊。过去16年有明显的风湿性心脏瓣膜病病史。用力和矫形时均有呼吸困难史。经检查,患者有轻度肝肿大伴腹水。脾尖在肋缘下方可触及。患者在三尖瓣区也有明显的泛收缩期杂音。CBC的表现平平。肝酶和胆红素轻度升高。病毒血清学阴性。肾功能正常。病人接受了超声检查以确定肝功能紊乱的原因。肝脏超声扫描显示肝脏回声变粗,表面结节性,提示肝硬化(图1)。脾脏轻度肿大。少量腹水。多普勒门静脉成像显示门静脉内存在脉动性血流,每次收缩期门静脉血流低于基线(图2)。可见相关的下腔静脉和肝静脉明显扩大(图3),心室扩张(右侧大于左侧)。(图4)随后的心脏回声证实存在多发性瓣膜疾病,以TR为主。图1图1:肝脏超声扫描显示回声变粗,表面结节状。伴有腹水。门静脉搏动信号:潜在三尖瓣返流伴充血性衰竭2 / 4图2:门静脉频谱多普勒示搏动波形图3图3:肝静脉水平扫描显示肝静脉明显增大,伴有严重扩张的下腔静脉。图4:心脏水平灰度扫描显示心室明显扩张。正常受试者在屏气期间的频谱多普勒分析显示门静脉流速变化极小。轻度相型很可能是右房压传递变化的反映,小静脉、窦状静脉和小门静脉分支的阻力明显减弱。当门静脉最小流速降至或低于基线2时,就会出现门静脉搏动。脉搏性门静脉流动常见于三尖瓣反流。在他们对17名患者的研究中,Abu Yousef等人发现17名患者中有15名出现三尖瓣反流。三尖瓣反流最常见的原因是由于左心室衰竭、二尖瓣狭窄、门静脉高压、肺动脉狭窄或房间隔缺损引起的右心室扩张。在严重三尖瓣反流(3级或以上)患者中,瓣膜泄漏增加门静脉循环远端血管阻抗,这种阻抗在心室收缩晚期达到最大。这反过来又可能阻碍门静脉的顺行血流,导致心室收缩期间血流返回基线甚至逆转。在更严重的肝窦充血病例中出现后一种血流模式。这些门静脉血流模式可能是TR的特征,提示相关的充血性心力衰竭3。搏动性门静脉信号潜在三尖瓣返流伴充血性衰竭的指征3 / 4其他可能导致门静脉搏动性流动的原因包括主动脉-右心房瘘或门静脉与肝静脉之间的瘘。由于这两种原因都是罕见的,因此脉动性门静脉血流的发现应考虑TR合并CHF的可能性。此类病例的其他辅助表现包括下腔静脉扩张(直径大于2.5 cm)和频谱波形异常的肝静脉。慢性窦性充血可引起肝脏肝硬化改变,如本例肝硬化相关的继发性表现,导致活回声纹理变粗,表面结节,脾肿大和腹水。灰度成像通常也显示继发于TR的RV和RA明显扩张。学习要点:放射科医生应注意继发于潜在心脏病理的肝功能障碍的可能性。在门静脉搏动的患者中,最可能的原因是潜在的TR与相关的CHF。引用1。泰勒KJW,伯恩斯PN。骨盆和腹部双多普勒扫描。超声医学生物杂志1985;11:643 - 658。2. 阿布-尤瑟夫MM,米拉姆SG,法纳RM。 脉动性门静脉血流:双多普勒超声显示的三尖瓣反流的征象。学杂志。1980;155:785 - 788。3.胡志强,陈志强,陈志强,等。充血性心力衰竭的门静脉血流:脉冲双工超声表现。放射学。1990;174(3): 733 - 736。4. 邱HT。大下腔静脉:右髂总动脉与下腔静脉之间的动静脉瘘征象。。本部同样高品质1982; 10:291 - 293 5。Lee RA, Lewis BD,超声波。射线照相。1990;10:369 - 371。门静脉搏动:潜在三尖瓣返流伴充血性心力衰竭的指征4 / 4

Dissection in a hypoplastic vertebral artery is extremely rare and has never been described previously in adults. We report a case of a 28 year old male who developed stroke following dissection in a hypoplastic left vertebral artery. In addition to describing the imaging findings of this rare combination, the authors discuss the role of hypoplasia as a predisposing factor for dissection.

The middle glenohumeral ligament [MGHL] demonstrates the greatest variation in size and thickness, of all the three glenohumeral ligaments seen on MR imaging of the shoulder. We report a series of patients who underwent routine MR imaging of the shoulder for unrelated pathologies in whom a significant number of MGHL variants were identified. The importance of recognizing this lies in avoiding overdiagnosing or mistaking these for labral or ligamentous pathology. We conclude with a brief review of the importance and functions of the MGHL.

Objectives: Intussusception, a common cause of an acute abdomen in children less than 2 years old can lead to bowel ischaemia with associated gangrene in undiagnosed cases with potentially fatal consequences. Air insufflation fluoroscopy is the method most commonly utilized at the Radiology Department of the University Hospital of the West Indies (UHWI) for both diagnosis and treatment of this condition. Internationally accepted rates of reduction are in excess of 70%, and perforation rates 3% or less. The reduction and perforation rates at the UHWI were previously undocumented.We aim to compare the reduction and perforation rates by air insufflation at the UHWI with the current standards in the literature. We also aim to identify potential causes of differences in rates and possible solutions for improving reduction rates. We also plan to propose a protocol to be instituted for all patients presenting for investigation and management of intussusception at UHWI.Method: A retrospective review of all cases performed between 1998 and 2003 was done using the logbooks available in the x-ray department.Results: There were 91 cases of suspected intussusception, Ages ranged from 6 weeks to 16 months. 51 cases were confirmed. The reduction rate was 56%. The perforation rate was 3.3%, not statistically significant from reports in the literature.Conclusions: Our reduction rate was found to be below the internationally accepted standard. This was thought to be due to lack of standard equipment and level of operator experience.
目的:肠套叠是2岁以下儿童急腹症的常见病因,在未确诊的病例中可导致肠缺血伴坏疽,具有潜在的致命后果。在西印度群岛大学医院(UHWI)放射科,空气充气透视是诊断和治疗这种疾病最常用的方法。国际公认的减径率超过70%,射孔率不超过3%。UHWI的减少率和射孔率以前没有记录。我们的目的是比较在UHWI空气膨胀的减少和射孔率与目前文献中的标准。我们还旨在确定率差异的潜在原因和提高降低率的可能解决方案。我们还计划提出一项方案,为所有在UHWI进行肠套叠调查和管理的患者制定。方法:回顾性回顾1998年至2003年期间所有病例,使用x线部可用的日志。结果:91例疑似肠套叠,年龄6周至16个月不等。确诊病例51例。还原率为56%。穿孔率为3.3%,从文献报道来看无统计学意义。结论:我们的还原率低于国际公认的标准。这被认为是由于缺乏标准设备和操作人员的经验水平。

Healthcare Blogging-A review 医疗保健博客-一篇评论
Pub Date : 2008-12-31 DOI: 10.5580/14ea
S. Sethi
The Internet is changing medicine and web 2.0 is the current buzz word in the world wide web dictionary. According to Dean Giustini in British Medical Journal, web 2.0 means “the web as platform” and “architecture of participation”. It is the web or internet information which is created by the users themselves. Web 2.0 is primarily about the benefits of easy to use and free internet software. For example, blogs and wikis facilitate participation and conversations across a vast geographical expanse. Information pushing devices, like RSS feeds, permit continuous instant alerting to the latest ideas in medicine. Multimedia tools like podcasts and videocasts are increasingly popular in medical schools and medical journals. Recently, there has been no escaping the mention of blogs in the media. Blogging has emerged as a social phenomenon, which has impacted politics, business, and communication. Medical field or healthcare is also not immune to this global phenomenon. Hence this chapter will deal with this phenomenon of blogging, with emphasis on what is a blog, historical significance, various software platforms available, blogging for a physician, pros and cons of blogging in healthcare, examples from popular healthcare blogs and prediction for future trends. This chapter will familiarize the reader about healthcare blogs and their impact on healthcare.
互联网正在改变医学,web2.0是当前万维网词典中的热门词汇。根据迪恩·朱斯蒂尼在《英国医学杂志》上的说法,web 2.0意味着“作为平台的网络”和“参与的架构”。它是由用户自己创建的网络或互联网信息。Web 2.0主要是关于易于使用和免费的互联网软件的好处。例如,博客和wiki促进了跨地域的参与和对话。像RSS提要这样的信息推送设备,可以让人们对医学上的最新观点保持持续的即时提醒。像播客和视频广播这样的多媒体工具在医学院和医学期刊中越来越流行。最近,媒体上总是会提到博客。博客已经成为一种社会现象,影响了政治、商业和交流。医疗领域或保健也不能幸免于这种全球现象。因此,本章将讨论博客的这种现象,重点是什么是博客,历史意义,各种可用的软件平台,医生博客,医疗保健博客的利弊,流行的医疗博客的例子和对未来趋势的预测。本章将使读者熟悉医疗保健博客及其对医疗保健的影响。

The sacroiliacal joint can be source of low back pain and radiofrequency denervation was reported to provide pain relief in patients with sacroiliac joint syndrome. We report about our experience with 30 difficult to treat patients with low back pain because of sacroiliac joint syndrome. Six months after the radiofrequency denervation 47% of the patients showed a lasting pain relief. Radiofrequency denervation shows promising results as part of the treatment of sacroiliac joint pain, but randomized controlled trials with larger sample size are thoroughly needed to further determinate its effiacy.
骶髂关节可能是腰痛的来源,据报道射频去神经可以缓解骶髂关节综合征患者的疼痛。我们报告了30例因骶髂关节综合征而腰痛难治的患者的经验。射频去神经六个月后47%的患者疼痛持续缓解。射频去神经支配作为治疗骶髂关节疼痛的一部分显示出令人鼓舞的结果,但需要更大样本的随机对照试验来进一步确定其有效性。
