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 It has been replaced by the considerably more expensive magnetic resonance imaging and computed tomography, despite the fact that, as first examination, it can usefully supplement the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...

BACKGROUND & AIMS: We performed a multicenter study to determine whether transabdominal bowel wall ultrasonography, a non-invasive procedure that does not require radiation, can be used to monitor progression of Crohn's disease (CD). METHODS: We performed a 12-month prospective, non-interventional study at 47 sites in Germany, from December 2010 through September 2014. Our study included 234 adult patients with CD who experienced a flare, defined as Harvey-Bradshaw index score of ≥7...

PURPOSE: Chronic obstructive defecation can occur in patients with Hirschsprung Disease (HD) and internal anal sphincter (IAS) achalasia. Injection of Botulinum Toxin (BoTox) into the IAS can temporarily relieve obstructive defecation, but can be challenging when performed by tactile sense alone. We compared results of BoTox injections with and without ultrasound (US) guidance. METHODS: We retrospectively reviewed BoTox injections into the IAS for obstructive defecation over 5years...

PURPOSE: Neoadjuvant chemoradiotherapy is the preferred standard of care for clinical stages II-III rectal cancer. It is uncertain whether clinically node negative (cN-) tumors found to be pathologically stage III could be optimally treated with surgery alone and avoid adjuvant treatments. The aim of our study was to define the outcomes of such patients. METHODS: Patients undergoing radical surgery using total mesorectal excision (TME) techniques for rectal cancer (≤12 cm from the anal verge) with curative intent during 2000-2012 and found to have stage III disease on final pathology were identified from a prospectively maintained database...

We report the case of a 67-year-old woman with a carcinoid tumor of midgut origin who developed carcinoid heart disease and died because of bowel perforation. Echocardiography allowed the diagnosis, recognizing the typical abnormalities of tricuspid and pulmonary valve leaflets. The sonographic examination also evidenced peculiar alterations of the right heart hemodynamics: end-diastolic reversal of flow at the level of the pulmonary valve, reduced respiratory excursion without enlargement of the inferior vena cava, and biphasic hepatic venous flow without respiratory variation...

We report the case of a 53-year-old female patient who was transplanted with the liver of a 71-year-old male donor for advanced primary sclerosing cholangitis (PSC) and who additionally was diagnosed with a histologically non-classifiable colitis shortly before transplantation. Upon follow-up abdominal ultrasound 4 months after transplantation, a liver lesion measuring 16 × 23 mm was detected in the transplanted liver. This lesion had not been noticed immediately after transplantation and showed a pattern suspicious for malignancy in contrast-enhanced ultrasound...

Contrast-enhanced ultrasonography (CEUS) and strain elastography (SE) are diagnostic imaging methods, which are still not routinely used in the clinical management of inflammatory bowel diseases. However, there are studies in the literature reporting on the use of both CEUS and SE in patients with bowel obstruction due to Crohn's disease, documenting the usefulness of these two methods in the differentiation between inflammation and fibrosis affecting the bowel wall. The aim of this case report is to evaluate the usefulness of CEUS and SE performed in a patient with Crohn's disease, who was admitted to hospital with bowel obstruction due to terminal ileal stricture and submitted to ileocecal resection...

Diverticulosis of the colon is a common condition in western countries. Acute diverticulitis may occur in 10% to 25% of the patients, sometimes associated with the presence of complications such as abscess, fistula, and perforation. Early diagnosis and accurate assessment of acute diverticulitis are necessary to start an efficacious treatment promptly, either conservatively or by surgery. The clinical picture may mimic other abdominal conditions; therefore, imaging techniques such as ultrasound or computed tomography are usually recommended, although they are expensive, examiner dependent, and potentially harmful...

Contrast-enhanced Ultrasound (CEUS) represents a complementary technique to grey-scale and colour Doppler ultrasonography (US) which allows for real-time visualization and characterization of tissue perfusion. Its inherent advantages in the child makes US an ideal imaging modality; repeatability and good tolerance along with the avoidance of computed tomography (CT), a source of ionizing radiation, renders US imaging desirable. Although currently paediatric CEUS is principally used in an "off-label" manner, US contrast agents have received regulatory approval for assessment of paediatric focal liver lesions in the United States of America...

Ultrasound is an invaluable imaging modality in the evaluation of pediatric gastrointestinal pathology; it can provide real-time evaluation of the bowel without the need for sedation or intravenous contrast. Recent improvements in ultrasound technique can be utilized to improve detection of bowel pathology in children: Higher resolution probes, color Doppler, harmonic and panoramic imaging are excellent tools in this setting. Graded compression and cine clips provide dynamic information and oral and intravenous contrast agents aid in detection of bowel wall pathology...

REVIEW
Ryan W Stidham, Peter Dr Higgins
Crohn's disease (CD) activity assessments are dominated by inflammatory changes without discrete measurement of the coexisting fibrotic contribution to total bowel damage. Intestinal fibrosis impacts the development of severe structural complications and the overall natural history of CD. Measuring intestinal fibrosis is challenging and existing methods of disease assessment are unable to reliably distinguish fibrosis from inflammation. Both the immediate clinical need to measure fibrosis for therapeutic decision-making and the near-future need for tools to assess pipeline anti-fibrotic medications highlight the demand for biomarkers of fibrosis in CD...
