Autoimmune pancreatitis is a chronic fibroinflammatory autoimmune mediated disease of the pancreas. Clinically, obstructive painless jaundice and upper abdominal pain are the main symptoms. Focal AIP is characterized by segmental involvement of pancreatic parenchyma and it is often radiologically represented by a pancreatic mass. In these cases, the diagnosis can be very challenging, since it may be easily confused with pancreatic cancer. Therefore, we suggest a combined approach of imaging tests as the diagnostic workup. EUS study combined with CEUS and elastography, if available, increases the accuracy of the method to rule out cancer. Moreover, the lesion should always be sampled under EUS guidance to obtain a cyto/histological diagnosis. The diagnostic workup should also include the use of diagnostic clinical criteria (extrapancreatic lesions, steroid response) and laboratory findings (CA 19.9 and IgG4 evaluations).

Purpose Ultrasound elastography is a noninvasive method for liver stiffness measurement (LSM) with the aim of reflecting approximate liver fibrosis load. Despite minimal evidence, current guidelines recommend 10 min of rest and breath hold prior to measurements and offer no advice concerning recent alcohol consumption, leading to challenges in clinical practice. We aimed to investigate how LSM in healthy adults is influenced by physical exercise, recent alcohol consumption, and respiration. Materials and Methods 42 healthy subjects aged 21-36 years were included. LSM using point shear wave elastography (pSWE) was performed in five stages: baseline, after physical activity, after registration of alcohol consumption, and during breath hold compared to free breathing. Results LSM values were significantly increased following physical exercise compared to baseline values (4.1±0.8 vs. 3.8±0.8 kPa, p=0.01). Alcohol consumption during the last 72 h (0-27 alcohol units) did not significantly affect LSM. There was no significant difference between LSM during breath hold and free breathing. Conclusion In healthy subjects, LSM increased after recent physical exercise, while alcohol consumption 24-72 h prior to examination did not have a significant impact. There was no clinically significant effect of breath hold on LSM. Our study supports present guidelines recommending rest prior to LSM, while indicating that breath hold may not be mandatory. Recent moderate alcohol exposure may affect LSM to a lesser extent than commonly believed.
目的超声弹性成像是一种无创的肝刚度测量方法,旨在反映肝纤维化的近似负荷。尽管证据很少,但目前的指南建议在测量前休息10分钟并屏住呼吸,并没有对近期饮酒提出建议,这给临床实践带来了挑战。我们的目的是调查健康成人的LSM如何受到体育锻炼、最近饮酒和呼吸的影响。材料与方法选取年龄21 ~ 36岁的健康受试者42例。使用点横波弹性成像(pSWE)的LSM分为五个阶段:基线、体力活动后、饮酒登记后和屏气与自由呼吸比较期间。结果运动后LSM值较基线值显著升高(4.1±0.8 kPa vs. 3.8±0.8 kPa, p=0.01)。最后72小时内的酒精消耗(0-27酒精单位)对LSM没有显著影响。屏气与自由呼吸时LSM无显著性差异。结论健康受试者近期体育锻炼后LSM升高,而体检前24-72 h饮酒对LSM无显著影响。屏气对LSM无明显的临床影响。我们的研究支持目前的指导方针,建议在LSM之前休息,同时表明屏气可能不是强制性的。近期适度饮酒对LSM的影响程度可能比通常认为的要小。

Digital papillary adenocarcinoma (DPA) is a malignant neoplasia of the eccrine glands primarily found at the fingers (A. ArsalanWerner et al. Handchirurgie, Mikrochirurgie, plastische Chirurgie 2013; 45: 287–292). It was first described by Helwig 1984 (E. B. Helwig. Journal of Cutaneous Pathology 1984: 11: 415-420). These tumors have metastatic potential (W. H. Duke et al. The American journal of surgical pathology 2000; 24: 775–784) and a high tendency to recur if not fully resected (T. Kobayashi et al. The American Journal of dermatopathology 2016; 38: 910–914). Clinically, these tumors normally present as a painless mass with no signs of inflammation and slow growth over months to years before patients seek medical attention. Imaging diagnosis of digital papillary adenocarcinomas is challenging because there are no specific imaging criteria. We present the case of a 68-year-old male with a local digital papillary adenocarcinoma of the right thumb with cystic appearance. Case Report

Introduction Fibular hemimelia is a congenital lower limb anomaly characterized by the partial or complete absence of the fibula. It includes a spectrum ranging from mild fibular hypoplasia to complete fibular aplasia. Although rare in occurrence, it is the most common congenital absence of long bone of the extremities 1.

In most cases large vessel occlusion (LVO) in the anterior circulation causes a severe stroke syndrome with a high National Institutes of Health Stroke Scale score (NIHSS). However, there is also a smaller group of patients (up to 10 % of all LVO) presenting with a minor stroke syndrome, transient or even absent neurological symptoms, who may develop early clinical deterioration. They may be candidates for thrombolysis and mechanical thrombectomy (MT). Due to low clinical suspicion, many of these patients are not included in the diagnostic fast track of a comprehensive stroke center with immediate vessel imaging by means of CTor MR-angiography. In this scenario neurosonography can be the first vessel imaging performed. We present such a clinical case and its neurosonographic findings of a distal M1 middle cerebral artery occlusion (MCA) with an emphasis on the early temporal branch (ETB) as an important M1-M2 collateral pathway (aside from established neurosonological signs).

Purpose: The COVID-19 pandemic poses new challenges for the medical community due to its large number of patients presenting with varying symptoms. Chest ultrasound (ChUS) may be particularly useful in the early clinical management in suspected COVID-19 patients due to its broad availability and rapid application. We aimed to investigate patterns of ChUS in COVID-19 patients and compare the findings with results from chest X-ray (CRX).
Materials and methods: 24 patients (18 symptomatic, 6 asymptomatic) with confirmed SARS-CoV-2 by polymerase chain reaction underwent bedside ChUS in addition to CRX following admission. Subsequently, the results of ChUS and CRX were compared.
Results: 94% (n=17/18) of patients with respiratory symptoms demonstrated lung abnormalities on ChUS. ChUS was especially useful to detect interstitial syndrome compared to CXR in COVID-19 patients (17/18 vs. 11/18; p<0.02). Of note, ChUS also detected lung consolidations very effectively (14/18 for ChUS vs. 7/18 cases for CXR; p<0.02). Besides pathological B-lines and subpleural consolidations, pleural line abnormality (89%; n=16/18) was the third most common feature in patients with respiratory manifestations of COVID-19 detected by ChUS.
Conclusion: Our findings support the high value of ChUS in the management of COVID-19 patients.

Segmental testicular infarction is a relatively uncommon and benign finding. It occurs predominantly in the second and third decade of life. The main symptoms are unilateral and scrotal as seen in more common conditions such as testicular torsion, epididymitis, orchitis, or blunt trauma. The primary testis investigation method is ultrasonography (US) with color Doppler. Normally segmental testicular infarction is seen as a round or wedge-shaped hypoechoic lesion within the testicle in combination with absent or low blood flow. In contrast, vascular testicular lesions are often malignant. However, US alone cannot rule out testicular neoplasms, since hypovascularity of testicular tumors has been described.

Ultrasound is a ubiquitous and indispensable diagnostic and therapeutic tool in medicine. Due to modern equipment and automatic image optimization, the introduction of ultrasound imaging currently requires only little technical and physical knowledge. However, in-depth knowledge of the device functions and underlying mechanisms is essential for optimal image adjustment and documentation. From a medical as well as an aesthetic point of view, the goal should always be to achieve the best possible image quality. The first part of this article provides an overview of the handling of ultrasound systems, fundamental adjustments, and their optimization in B-mode ultrasound.
