Mucinous appendiceal neoplasms: Report of a case and brief literature review.

Introduction: Appendiceal tumors are rare neoplasms detected in about 2 % of appendicectomies. The clinical presentation is often unspecific, varying from unspecific abdominal pain or presenting as an acute appendicitis or being asymptomatic.

Case Presentation: We present a case of a patient presenting as an acute appendicitis with a mucocele, and then classified as HAMN.

A rare case of pneumatosis cystoides intestinalis with bowel perforation and secondary sepsis.

Materials And Methods: We present here the case of an 83 y.o. male with intestinal perforation from pneumatosis cystoides intestinalis and consequent sepsis.

Multiparametric ultrasound in the diagnosis and monitoring of ischemic colitis: description of a case of ischemic colitis of the right colon and revision of the literature.

The aim of this paper is to describe the usefulness of multiparametric US in the diagnosis and subsequent follow-up of a case of right-side ischemic colitis and to present a review of the data reported in the literature. Ischemic colitis is frequently diagnosed in the field of gastroenterology. Diagnosis is usually based on the outcome of endoscopy and histological examination, and in case of right-side ischemic colitis also on the results of contrast-enhanced CT.

Strain elastography in Crohn's disease: the role of visual observation and semiquantitative parameters.

Strain elastography is a recently developed ultrasound method that seems to contribute to the diagnosis and monitoring of inflammatory bowel diseases. This pictorial essay aims to present the feasibility of strain elastography in clinical practice by comparing visual observation and semiquantitative parameters with endoscopic or radiological images in some common cases of Crohn's disease. In our opinion, strain elastography with visual observation is easily performed in connection with B-mode ultrasound and color Doppler imaging and may provide relevant information.

Contrast-enhanced ultrasonography in clinical practice in Crohn's disease: feasibility of destruction/replenishment method and software analysis.

The aim of this Pictorial Essay is to evaluate the feasibility in the clinical practice of CEUS destruction/replenishment method and time intensity curve (TIC) analysis using the available software in patients with Crohn's disease. The ultrasound (US) procedure using contrast agent is briefly described, elaboration and analysis of the US sequences are explained in detail, and some advantages and disadvantages of the method are highlighted. The Authors suggest that the destruction/replenishment method is useful and time-saving in Crohn's disease if multiple measurements are required on intestinal portions adjacent to each other or in different locations.

Extragenital malignant mixed mesodermal tumor: A case report.

Introduction: Primary malignant mixed mesodermal tumor (MMMt, also called malignant mixed Mullerian tumor and designated in the WHO classification of female genital tract neoplasms as carcinosarcoma) is an infrequent tumor that develops usually in the uterus and more rarely in the ovary. Extragenital tumor, including primary peritoneal MMMt, is an extremely rare and aggressive neoplasm with only few case reported in the literature.

Presentation Of Case: We report a case of a 70-year's old female who presented with nausea and abdominal discomfort for 6 months.

Real-time elastography in Crohn's disease: feasibility in daily clinical practice.

Ultrasound (US) is the first-line investigation in patients with abdominal symptoms and it has a role in the diagnosis and monitoring of inflammatory bowel diseases. Strain elastography (SE) is a US method for estimating tissue elasticity. This method is still not routinely used in clinical practice, although it is suggested by the EFSUMB Guidelines for the characterization of intestinal stenosis in Crohn's disease.

Feasibility of CEUS and strain elastography in one case of ileum Crohn stricture and literature review.

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.

Diagnosis of one small bowel tumor: the role of conventional ultrasound and elastography.

Neuroendocrine tumors are the most common primary tumors of the small bowel, but diagnosis is usually delayed as the lesions are small and symptoms are mild or nonspecific. Diagnosis of this disease is currently based on radiologic or endoscopic findings. Ultrasound (US) is used as a first-line examination in patients with abdominal symptoms, as this technique permits an overall view of the gastrointestinal tract providing diagnosis of inflammatory and/or neoplastic disorders in a large proportion of patients.

Feasibility of real-time strain elastography in colonic diseases.

Real-time strain elastography is not routinely performed in clinical practice for characterizing gastrointestinal tract diseases, and there are few studies in the literature on the subject. The recent EFSUMB guidelines suggest the use of this method in the diagnosis of neoplastic lesions and in the characterization of bowel strictures in patients with Crohn's disease. The purpose of this pictorial essay is to evaluate the feasibility of strain elastography in some pathologies of the colon frequently encountered in daily clinical practice and to compare elastography images with corresponding endoscopic and radiographic images.

Contrast-enhanced sonography in the diagnosis of hepatic hemangiomas: atypical appearance due to the washout of microbubbles.

Contrast-enhanced sonography (CEUS) examination permits identification of hemangioma of the liver in most cases. This method is particularly useful when the ultrasound pattern is atypical on standard grayscale examination. CEUS appearances suggestive of hemangioma are peripheral globular enhancement, progression of enhancement toward the center of the nodule, and persistence of enhancement in the late phase.

Referrals for bowel ultrasound in clinical practice: a survey in 12 nationwide centres in Italy.

Background: The value of ultrasound (US) in assessing gastrointestinal diseases is well documented, but its demand in clinical practice is unknown. This survey evaluated the demand for bowel US in Italy.

Methods: Twelve sonographers of the Gastroenterology Section of the Italian Society of Ultrasound participated in a 1-month survey; they compiled a questionnaire assessing total number of patients referred for abdominal US and for gastrointestinal tract US, type of referring physician, indications and results of examinations.

Contrast-enhanced sonography in the diagnosis of acute mesenteric ischemia: case report.

Acute mesenteric ischemia is a serious condition associated with high mortality. Multislice CT and magnetic resonance angiography have proved accurate in diagnosing this pathology, which requires a prompt diagnosis to start appropriate therapy. We report the case of an 87-year-old woman with acute mesenteric ischemia, in whom contrast-enhanced sonography visualized the occluded superior mesenteric artery and the infarcted portion of the intestine.

Contrast-enhanced sonography of a hepatocellular carcinoma undergoing spontaneous necrosis.

Spontaneous necrosis of hepatocellular carcinoma (HCC) is rare. We report the case of a 72-year-old woman with an HCC nodule that underwent necrosis after sonographically guided needle biopsy. Baseline sonographic examination revealed only a nonspecific change in the echogenicity of the lesion.
