Crohn's disease (CD) is an inflammatory chronic bowel disorder; it can involve the whole gastrointestinal tract, but its localization in the ileum or colon is most common. The reference standard for the diagnosis of CD is ileocolonoscopy with histologic assessment. The reference standard for the detection of any complications is surgery. However, imaging techniques have an important role both in the detection/localization of CD and in the follow-up of CD patients. In the last few years, the technical development of ultrasound equipment, the advent of new technologies such as elastography and mostly the increased expertise of sonographers have boosted the role of bowel ultrasound in assessment of the gastrointestinal tract...

: Identifying the etiology of acute pelvic pain in girls is often clinically challenging. Particularly in young girls, it is often difficult to determine if acute pelvic symptoms are originating from a gynecologic source or from a genitourinary or gastrointestinal etiology based on the child's clinical examination alone. Therefore, imaging plays a key role in establishing a diagnosis and in directing medical and surgical treatment. Pediatric gynecologic conditions, which can present acutely with pain or mass or both include ovarian torsion, hematometrocolpos, pelvic inflammatory disease, inguinal hernias containing an ovary or the uterus or both, adnexal cysts, pregnancy, vaginal foreign bodies, and ovarian vein thrombosis...

Tuberculous peritonitis is rare in the United States but continues to be reported to occur in certain high-risk populations, which include patients with AIDS or cirrhosis, patients on continuous ambulatory peritoneal dialysis, recent immigrants from areas of high endemicity, and those who are immunosuppressed. The diagnosis of this disease requires a high clinical index of suspicion and should be considered in the differential of ascites with a lymphocyte predominance and serum-ascitic albumin gradient of <1...

PURPOSE: The aim of this study is to assess gastric emptying in experimental necrotizing enterocolitis (NEC) and its diagnostic significance using non-invasive ultrasound imaging. METHODS: Fourteen neonatal mice (C57BL/6) were randomized into two groups: NEC [n=10] and control [n=4]. NEC was induced by gavage feeding of hyperosmolar formula, hypoxia, and lipopolysaccharide between postnatal day 5 (P5) and 9 (P9). Stomach volume was measured using a 40-MHz ultrasound transducer on P5 and P9...

BACKGROUND: Distinguishing fibrosis from inflammation in an intestinal stricture in Crohn's disease is quite difficult. The absence of signs of inflammation on CT or MRI does not prove the absence of inflammation, as most strictures have a mix of fibrosis and inflammation. Identifying refractory fibrosis and distinguishing the patients who will respond to anti-inflammatory therapy from those who will require surgery are important clinical requirements, and several new technologies in imaging and serum biomarkers are being applied to this problem...

BACKGROUND: Inflammation, fibrosis, and muscular hypertrophy lead to thickened bowel in Crohn's disease forming strictures. Ultrasound shear wave elastography (SWE) measures bowel wall stiffness. Contrast-enhanced ultrasound (CEUS) uniquely detects bowel wall inflammation. We aim to correlate SWE of ileal Crohn's disease in vivo to CEUS peak enhancement and pathology grades of inflammation, fibrosis, and muscular hypertrophy. METHODS: In a prospective institutional review board-approved study, 105 consecutive ileal patients with Crohn's disease received ultrasound...

Magnetic resonance imaging (MRI) plays an important role in the staging and restaging of rectal cancer. Multiplanar high-resolution (≤3-mm section thickness) T2-weighted images are the primary sequences used for rectal cancer staging. No preprocedural bowel cleansing regimen, intravenous contrast material, nor endorectal coil is necessary. MRI is highly accurate for differentiating T1-T2 disease from T3 and T4 disease, an important distinction as patients with T3 and T4 tumors typically undergo preoperative neoadjuvant chemoradiation before resection...

The main challenges of imaging for endometriosis are the detection of nonovarian disease and the evaluation of the extension of the disease into pelvic structures. Transvaginal ultrasonography (TVS) has been proposed as the first-line imaging technique because it allows extensive exploration of the pelvis. The "typical" endometrioma is a unilocular cyst with homogeneous low-level echogenicity (ground glass echogenicity) of the cyst fluid. The use of color Doppler helps avoid classifying malignancies as endometriomas, defining the presence of vascular flow in papillations...

Cholangitis is common in felines, including neutrophilic, lymphocytic, and chronic cholangitis (liver fluke). History, physical examination, laboratory testing, and abdominal ultrasound support a diagnosis. Diagnosis using hepatic histopathology and/or bile analysis is ideal but not always practical. Neutrophilic cholangitis is associated with bacterial cholecystitis, pancreatitis, and inflammatory bowel disease. The typical presentation is a short illness with lethargy, inappetence, pyrexia, and jaundice. Lymphocytic cholangitis, suspected to be immune-mediated, can have a prolonged clinical course with weight loss and ascites as the predominant features...

INTRODUCTION: This case report is the first in the Australian literature of a patient, without prior diagnosis, presenting with a bowel obstruction secondary to lobular breast cancer. This highlights a relatively rare cause of bowel obstruction, but also the importance of breast self-examination as a compliment to the current BreastScreen Australia program.

INTRODUCTION: Gastrointestinal stromal tumors (GIST) are tumors of mesenchymal origin commonly detected in stomach and small bowel. GIST arising primarily from the anal canal is extremely rare. Due to the malignant potential, these tumors are treated with radical surgery like abdominoperineal resection. But with the advent of imatinib therapy and a better understanding of the tumor biology, some cases have been successfully treated with wide local excision. PRESENTATION OF CASE: We describe a case of a 70-year-old lady presenting with a 2cm mass in the anal canal...

The high frequency of intestinal strictures in patients with Crohn's disease and the different treatment approaches specific for each type of stenosis make the differentiation between fibrotic and inflammatory strictures crucial in management of the disease. However, there is no standardized approach to evaluate and discriminate intestinal strictures, and until now, there was no established cross-sectional imaging modality to detect fibrosis. New techniques, such as contrast-enhanced ultrasound and sonoelastography allow the assessment of vascularization and mechanical properties of stenotic bowel tissue, respectively...

: Cross sectional Imaging plays an increasingly important role the diagnosis and management of Crohn's disease. Particular emphasis is placed on MRI and Ultrasound as they do not impart ionising radiation. Both modalities have reported high sensitivity for disease detection, activity assessment and evaluation of extra-luminal complications, and have positive effects on clinical decision making. International Guidelines now recommend MRI and Ultrasound in the routine management of Crohn's disease patients...

Extraintestinal manifestations are common in inflammatory bowel disease; however, muscular involvement in Crohn disease is rarely reported. We present a case of a 26-year-old male with ileocolonic Crohn disease who developed sudden tenderness in both calves. Doppler ultrasound was negative for deep vein thrombosis. Magnetic resonance imaging of the gastrocnemius muscle showed high intensity signal in the muscle fibers, and muscle biopsy demonstrated nonspecific lymphocytic myositis. Other relevant laboratory results included normal antineutrophil cytoplasmic antibodies and creatine kinase as well as elevated C-reactive protein, erythrocyte sedimentation rate, and anti-Saccharomyces cerevisiae IgG titer...

Ultrasound is an undervalued non-invasive examination in the diagnosis of colonic diseases. It has been replaced by the considerably more expensive magnetic resonance imaging and computed tomography, despite the fact that, as first examination, it can usefully supplement the diagnostic process. Transabdominal ultrasound can provide quick information about bowel status and help in the choice of adequate further examinations and treatment. Ultrasonography, as a screening imaging modality in asymptomatic patients can identify several colonic diseases such as diverticulosis, inflammatory bowel disease or cancer...

Ileocolic intussusception due to Burkitt lymphoma is extremely rare in adults. A man aged 17 years presented with a history of recurrent abdominal pain over the past 3 weeks. The abdomen was distended with diffuse tenderness, and bowel sounds were present. Abdominal ultrasound and CT scans showed evidence of small bowel obstruction with marked wall thickening in the ileocecal region and 'target' signs suggestive for intussusception. At laparoscopy, a mass involving the caecum and the terminal ileum was found, along with multiple locoregional nodes, which was highly suggestive of malignancy...

BACKGROUND: Contrast-enhanced ultrasound (CEUS) has become an established non-invasive, patient-friendly imaging technique which improves the characterization of lesions. In addition, dynamic contrast-enhanced ultrasound (DCE-US) provides valuable information concerning perfusion of examined organs. This review addresses current applications of CEUS in children, focused on DCE-US of the bowel wall in patients with Crohn disease, which enables realtime assessment of the bowel wall vascularity with semi-quantitative and quantitative assessment of disease activity and response to medical treatment...
