RATIONALE: Critical care ultrasound identifies the signs of free intraperitoneal air and echogenic free fluid always indicates hollow viscus perforation (HVP) and needs immediate surgical interventions. However, in rare cases, these classic signs may also mislead proper clinical decisions. We report perforated viscus associated large peritoneal effusion with initial critical care ultrasound findings, whereas computed tomography (CT) examination confirmed a giant stomach due to superior mesenteric artery syndrome (SMAS)...

Takayasu arteritis (TA) is a chronic nonspecific inflammation that commonly occurs in the aorta and its main branches. Most patients with TA are lack of clinical manifestations, leading to misdiagnosis. When the TA is correctly diagnosed, the patients may already have stenosis or occlusion in the involved arteries, resulting in arterial ischemia and hypoxia symptoms, and in severe cases it will be life-threatening. Contrast-enhanced ultrasonography (CEUS) is an emerging method for assessing TA, but the assessment relies heavily on experiences of radiologists performing manual and qualitative analyses, so the diagnostic results are often not accurate...

Acute cholecystitis is the most common diagnosable cause for right upper quadrant abdominal (RUQ) pain in patients who present to the emergency department (ED). However, over one-third of patients initially thought to have acute cholecystitis actually have RUQ pain attributable to other causes. Ultrasonography (US) is the primary imaging modality of choice for initial imaging assessment and serves as a fast, cost-effective, and dynamic modality to provide a definitive diagnosis or a considerably narrowed list of differential possibilities...

Introduction : Phylloides tumours (PTs) are rare fibroepithelial neoplasms that account for 0.3⁻0.9% of all breast tumours. These tumours typically occur in women aged 30⁻70 years. The occurrence of these tumours in older children and adolescents poses particular diagnostic and therapeutic problems. However, early diagnosis is mandatory because although most of the cases of PTs in children are benign, the borderline and malignant cases with potential negative outcomes cannot be excluded. Case presentation : A 12-year-old girl presented at the Paediatric Emergency Department for hyperaemia and warmth of the left breast that occurred a few days prior without fever...

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is an emerging risk factor for incident heart failure (HF). It is currently unknown whether NAFLD predicts all-cause mortality in patients admitted for acute HF. We aimed to assess whether NAFLD and its severity (diagnosed by ultrasonography and non-invasive fibrosis biomarkers) were associated with increased all-cause mortality in this particularly high-risk patient population. METHODS: We studied 264 elderly patients, who were consecutively admitted for acute HF to the hospital between years 2013 and 2015, after excluding those with acute myocardial infarction, severe valvular heart diseases, kidney failure, cancer, cirrhosis of any etiology or known chronic liver diseases...

Chest ultrasonography (CU) is a noninvasive imaging technique able to provide an immediate diagnosis of the underlying aetiology of acute respiratory failure and traumatic chest injuries. Given the great technologies, it is now possible to perform accurate CU in remote and adverse environments including the combat field, extreme sport settings, and environmental disasters, as well as during space missions. Today, the usage of CU in the extreme emergency setting is more likely to occur, as this technique proved to be a fast diagnostic tool to assist resuscitation manoeuvres and interventional procedures in many cases...

Introduction: An adnexal mass may be diagnosed after a routine pelvic ultrasonographic examination or an emergent hospital admission due to rupture of ectopic pregnancy, adnexal torsion or rupture of tuboovarian abscess. It is necessary to evaluate the origin of the mass initially and to classify patients who need further evaluation and treatment for an urgent condition. Case presentation: We report a case of sigmoid colon rupture due to sigmoid colon adenocarcinoma presenting as acute abdomen with left adnexal mass in a 28 years old woman...

Background: Optic nerve sheath diameter (ONSD) as measured by optic nerve sheath ultrasonography (ONSU) is used as a surrogate marker of intracranial pressure (ICP), especially in resource-limited settings. There is a growing interest in the use of ONSU in emergency and high-altitude setups. Notwithstanding multiple studies done on this subject, there is a paucity of data regarding standardization of techniques and comparison of ONSU with computed tomography (CT). Materials and Methods: Thirty-five patients with a diagnosis of high-altitude cerebral edema were enrolled in the study...

Shoulder dislocations are a common presentation to the emergency department. Although many cases may be diagnosed by history and clinical examination alone, imaging may help diagnose more challenging cases. Three-view radiographs are important for identifying subtle posterior dislocations, and ultrasonography has been gaining evidence as an alternate diagnostic modality. Intra-articular lidocaine and nerve blocks may improve pain control and reduce the need for procedural sedation. Multiple, evidence-based reduction techniques are described including tips for improving success...

Intestinal ultrasonography has emerged as a cheap, non-invasive and readily accessible modality for the assessment of a number of gastroenterological diseases. Over the last decade, particularly due to the widespread use of biological agents in Inflammatory Bowel Disease (IBD), guidelines regarding management and follow-up advise more regular disease assessment and surveillance in order to guide treatment adjustments, and provide more personalised care. Given the young age of the majority of patients with IBD the availability of an alternative modality to harmful radiation or the risks of endoscopy for this indication offers an appealing advantage...

Optical coherence tomography (OCT) was introduced as an imaging system, but like ultrasonography, other measures, such as blood perfusion and polarization of light, have enabled the technology to approach clinical utility. This review aims at providing an overview of the advances in clinical research based on the improving technical aspects. OCT provides cross-sectional and en face images down to skin depths of 0.4 to 2.00 mm with optical resolution of 3 to 15  μm. Dynamic optical coherence tomography (D-OCT) enables the visualization of cutaneous microvasculature via detection of rapid changes in the interferometric signal of blood flow...

INTRODUCTION: The incidence of acute appendicitis is approximately 250,000 cases per year in the United States with a lifetime risk of 7% (Gupta & Dupuy, 1997). However, despite strongly associated clinical signs, diagnostic accuracy based on history and physical exam alone is only 70% (Jess et al., 1981). This is in large part due to the multitude of mimics found in the differential diagnosis of appendicitis. As a result highly sensitive imaging such as computed tomography scan has become standard of care...

Scrotal pain is a common acute presentation for medical care. Testicular torsion and epididymo-orchitis are two diagnoses for which early detection is critical and their sonographic imaging features have been thoroughly described in the radiologic literature. Other important conditions for which radiologists must be aware have received less attention. This article will highlight key traumatic and non-traumatic causes of acute scrotal pain other than testicular torsion and epididymo-orchitis that may present in the emergency department setting...
