This study aimed to assess the application of ultrasonography for preoperative diagnosis of retroperitoneal fibrosis (RPF). A total of 51 patients with clinically suspected RPF underwent transabdominal ultrasonography and ultrasound-guided histopathologic biopsy (tAU-UGHB). Retroperitoneal fibrosis was diagnosed in 35 patients; of these, 31 cases (88.6%) received a diagnosis using tAU-UGHB. The ultrasonographic images mainly showed solid, irregular isoechoic masses, which were present behind the retroperitoneum and surrounded the abdominal aorta, inferior vena cava, and ureters and had clear borders with the encapsulated structures...

We report a case of an adnexal torsion in a 27-year-old woman in her 12th week of gestation. She presented with hypogastric and lumbar pain with biliary vomiting and nausea. Upon physical examination, tenderness in the right lower quadrant with rebound tenderness was apparent, and gynecological examination revealed right adnexal tenderness with absence of abnormal cervical discharge. The transvaginal ultrasonography demonstrated an enlarged cystic right ovary with no flow detected on color and power Doppler mode...

A 30-year-old woman experienced severe abdominal pain 8 days after vaginal delivery. The patient was diagnosed with hemoperitoneum due to rupture of the left uterine artery pseudoaneurysm, which was confirmed via ultrasound with color Doppler and computed tomography scans. This patient was treated with bilateral uterine artery embolization to maintain fertility. A uterine artery pseudoaneurysm that causes delayed postpartum hemorrhage can occur after cesarean section or vaginal delivery. A uterine artery pseudoaneurysm can be fatal, so its detection and diagnosis are critical...

Large-vessel vasculitis (LVV) is a group of diseases mainly comprised of giant-cell arteritis (GCA), Takayasu arteritis, and a series of rare diseases like Behçet's disease, IgG4-related disease, infectious aortitis, and other unfrequent entities. Besides clinical and laboratory features, Doppler sonography (DS) can assist in establishing the diagnosis. Its diagnostic sensitivity has been evaluated in various studies, most of them, however, in temporal arteritis (TA) respectively in LVV with involvement of the temporal artery...

Tubal choriocarcinoma is uncommon, and its magnetic resonance imaging characteristics have not yet been reported. In this report, a 39-year-old woman presented with irregular painless vaginal bleeding and a palpable left lower abdominal lump for 2 months following 6 weeks' amenorrhea and positive urine pregnancy test. Her serum β-human chorionic gonadotropin value was significantly increased. Ultrasound revealed a left adnexal mass, which showed no blood flow signal on Color doppler flow imaging. A further MR examination showed a well-defined cystic-solid mass with cystic component accounting for a large proportion in the left lower abdomen...

We describe a case of bladder cancer presenting with atraumatic chylous ascites, which remains an extremely rare presentation of this condition. A previously well, elderly ex-smoker with no prior history of abdominal surgery was referred for investigation of progressive dyspnoea, increasing peripheral oedema and new-onset ascites, on a background of long-standing alcohol consumption (four standard drinks daily). Liver biochemistry and coagulation profile were normal apart from marked hypoalbuminaemia. Doppler ultrasound of the liver demonstrated normal echotexture and patent vasculature...

REVIEW

The double aorta artifact was described and studied thoroughly twenty-five years ago. Despite this, it is still not commonly known today and can cause diagnostic difficulty. Total aortic duplication can be considered an anatomic defect whilst partial duplication mimics aortic dissection. In the literature, this artifact has been compared with a very rare anomaly, i.e. the occurrence of two aortas in one patient. Currently, however, the differentiation of this artifact from abdominal aortic dissection seems to be of greater significance...

Introduction Patients with acutely decompensated (AD) cirrhosis are at risk for developing acute-on-chronic liver failure (ACLF) syndrome. This syndrome is associated with a high short-term mortality rate. The aim of our study was to identify reliable early predictors of developing ACLF in cirrhotic patients with AD. Patients and Methods We assessed 84 cirrhotic patients admitted for AD without ACLF on admission. We performed routine blood testing and detailed ultrasound Doppler studies of systemic arteries and mayor abdominal veins and arteries...

INTRODUCTION: Blunt abdominal trauma is a common problem in children. Computed tomography (CT) is the gold standard for imaging in pediatric blunt abdominal trauma, however up to 50% of CTs are normal and CT carries a risk of radiation-induced cancer. Contrast enhanced ultrasound (CEUS) may allow accurate detection of abdominal organ injuries while eliminating exposure to ionizing radiation. METHODS: Children aged 7-18years with a CT-diagnosed abdominal solid organ injury underwent grayscale/power Doppler ultrasound (conventional US) and CEUS within 48h of injury...

BACKGROUND Ovarian torsion can be seen in the otherwise-normal ovary and is a challenging issue in the emergency department. The aims were (1) to evaluate and compare the surgically verified ovarian torsion cases in otherwise-normal ovaries and ovaries including a mass or cyst and (2) to investigate whether the normal-appearing ovaries on ultrasound examination affected the diagnosis of ovarian torsion or not. MATERIAL AND METHODS A retrospective cohort study design was used. The medical records of all postmenarchal adolescent girls with surgically verified ovarian torsion treated in a university hospital from 2010 to 2016 were reviewed...

Autologous breast reconstruction using the deep inferior epigastric artery perforator (DIEP) flap has become increasingly popular because of its unique advantages. However, compared with some other forms of abdominal-based autologous reconstruction, DIEP flaps are associated with an increased risk of venous congestion. Many techniques-or lifeboats-have been introduced to diagnose and treat this potentially devastating complication. In this case report, we describe a novel strategy to augment venous drainage when venous congestion is encountered...

Arterial stiffness can be evaluated by calculating pulse wave velocity (PWV), i.e., the speed with which the pulse wave travels in a conduit vessel. This parameter is being increasingly investigated in small rodent models in which it is used for assessing alterations in vascular function related to particular genotypes/treatments or for characterizing cardiovascular disease progression. This protocol describes an image processing algorithm which leads to non-invasive arterial PWV measurement in mice using ultrasound (US) images only...

We report a rare case of allograft loss from acute Page kidney secondary to trauma that occurred 12 years after kidney transplantation. A 67-year-old Caucasian male with a past surgical history of kidney transplant presented to the emergency department at a local hospital with left lower abdominal tenderness. He recalled that his cat, which weighs 15 lbs, jumped on his abdomen 7 d prior. On physical examination, a small tender mass was noticed at the incisional site of the kidney transplant. He was producing a normal amount of urine without hematuria...

REVIEW
Natalia Gonzalez, Togas Tulandi
A relatively new type of ectopic pregnancy is cesarean scar pregnancy (CSP). This is related to the increasing number of cesarean deliveries and the advances in imaging. There are 2 types of CSP: CSP with progression to the cervicoisthmic space or uterine cavity (type I, endogenic type) or with deep invasion of scar defect with progression toward the bladder and abdominal cavity (type II, exogenic type). The endogenic type of CSP could result in a viable pregnancy, yet with a high risk of bleeding at the placental site...

Metastatic melanoma is an aggressive disease that can spread to many organs of the body. In rare cases, it can spread to the gallbladder causing secondary lesions, yet presenting with little to no symptoms. Therefore, most cases of metastatic melanoma lesions to the gallbladder go undiagnosed. Here, we present the case of a 41-year-old male with a four-month history of melanoma of the face, with a postresection status, who presented with right upper quadrant abdominal pain. Doppler ultrasound and computed tomography confirmed the presence of a mass on the gallbladder...

REVIEW
K A Knight, S J Moug, M A West
BACKGROUND: Exercise in the preoperative period, or prehabilitation, continues to evolve as an important tool in optimising patients awaiting major intra-abdominal surgery. It has been shown to reduce rates of post-operative morbidity and length of hospital stay. The mechanism by which this is achieved remains poorly understood. Adaptations in mesenteric flow in response to exercise may play a role in improving post-operative recovery by reducing rates of ileus and anastomotic leak. AIMS: To systematically review the existing literature to clarify the impact of exercise on mesenteric arterial blood flow using Doppler ultrasound...

Takayasu's arteritis is known to cover the youngest age group in the etiology of secondary hypertension. The type 3 pattern is rare and involves the thoraco-abdominal aorta and its main abdominal branches. Here, we present the imaging results of a patient who had been followed up for systemic arterial hypertension and was diagnosed with Takayasu's arteritis type 3 by CT and MR angiography following bilateral detection of a parvus-tardus Doppler signal modulation in the renal arteries. We discuss the differential diagnoses that should be considered when observing a tardus-parvus Doppler signal...
