“…60 Edematous acute pancreatitis appears at a conventional B-mode examination, as widely described before, with a dimensional increase of the gland and a diffusely hypoechoic texture. The injection of contrast agent will show a diffused and homogeneous wash-in of the gland, with different degrees of enhancement, resulting in an increased echogenicity during the dynamic phases.…”

Acute pancreatitis is an inflammatory disorder of the pancreas characterized by abdominal pain and elevation of pancreatic enzymes in the blood. The pathogenesis is complex and partly unknown and the evolution is often unpredictable. Many efforts have been made to define this disease and its complications and to classify different grades of severity in order to formulate prognostic scores that could guide the physician in choosing the optimal therapeutic setting and procedures. The management of the patient with pancreatitis is not always optimal and differs among internist, gastroenterologist or surgeon. We think that a patient with clinical suspicion of acute pancreatitis is admitted to medical or surgical department depending on the availability of beds and not according to evidence-based medicine. The aim of this monograph is to identify the optimal management of patients with acute pancreatitis admitted to hospital.

“…CEUS had 88.6% Se, 97.8% Sp, 91.2% PPV, and 96% accuracy for the diagnosis of pseudotumoral CP, while in 94% of cases the inflammatory mass showed moderate enhancement following contrast, similar to the adjacent pancreatic parenchyma [20].…”

“…The US aspect of pseudotumoral CP is most often of a hypoechoic, imprecisely delineated mass in the head of the pancreas. CEUS is useful to differentiate among the two entities since pancreatic adenocarcinomas are hypoenhancing following contrast (due to massive desmoplastic reaction as well as poor vascularity), while the inflammatory pseudotumor in CP will be enhancing in the arterial phase [19][20][21].…”

“…It is characterized by a high level of gammaglobulins or IgG, presence of auto-antibodies, mild or absent clinical symptoms. Imaging techniques reveal an enlarged, "sausage-like" pancreas, with diffuse, irregular thinning of the Wirsung duct (WD), with possible stenosis of the retro-pancreatic main biliary duct and rarely cysts or calcifications in the pancreatic parenchyma [20]. Autoimmune pancreatitis is sometimes associated with other autoimmune diseases such as diabetes mellitus, inflammatory bowel disease, primary biliary cirrhosis, primary sclerosing cholangitis, or lupus.…”

“…The pancreas is enlarged, hypoechoic and with a compressed Wirsung duct. Following contrast bolus, the pancreas is moderate or hyperenhancing in the early arterial phase, but also with inhomogeneous enhancement due to lymphocytic infiltration and fibrosis [20].…”

Transabdominal ultrasound (US) is the first-line imaging method used to diagnose pancreatic lesions, but contrast techniques are needed to differentiate among inflammatory and malignant lesions, as well as between pseudocysts and cystic tumors. Contrast-enhanced (CE) ultrasonography has been proven to be a useful tool in this regard with performance similar to contrast-enhanced computer tomography/magnetic resonance imaging (CT/MRI), being also safer and nonirradiant. According to the EFSUMB guidelines on the nonhepatic use of contrast-enhanced ultrasound (CEUS), this method is useful to improve characterization of ductal adenocarcinoma; to differentiate between pseudocysts and cystic tumors; to differentiate vascular (solid) from avascular (liquid/necrotic) components of a lesion; to better define the dimensions and margins of a lesion, including its relationship with adjacent vessels; and to help the choice for a next imaging technique.

Indication/purpose: To review contrast‐enhanced ultrasound features of the most common pancreatic tumours. Methods: Contrast‐enhanced ultrasound (CEUS) can provide distinctive features of pancreatic tumours that are reported in the present paper, providing radiologic‐pathological correlations and clarifying the main differential diagnosis. Conclusion: Contrast‐enhanced ultrasound plays a well‐established role in the evaluation of pancreatic tumours. When possible, CEUS should be always performed after the initial US diagnosis, in order to improve the accuracy of the first line examination.

Mass-forming pancreatitis: Value of contrast-enhanced ultrasonography

Abstract: CEUS allowed diagnosis of mass-forming pancreatitis with diagnostic accuracy of 96%. CEUS significantly increases the diagnostic confidence with respect to basal US in discerning mass-forming pancreatitis from pancreatic neoplasm.
