Patients with PC experience a significant loss of adipose tissue during neoadjuvant chemotherapy, but no muscle wasting. An increase in muscle tissue during NT is associated with resectability.

Contrast-enhanced ultrasound (CEUS) is a relatively novel, but increasingly used, diagnostic imaging modality. In recent years, due to its safety, quickness, and repeatability, several studies have demonstrated the accuracy, specificity, and sensitivity of CEUS. The European Federation of Societies for Ultrasound in Medicine and Biology has recently updated the previous guidelines from 2012 for the use of CEUS in non-hepatic applications. This review deals with the clinical use and applications of CEUS for the evaluation of non-hepatic abdominal organs, focusing on renal, splenic, and pancreatic applications.

Background: The prevalence of symptoms in pancreatic cystic neoplasms (PCNs) is mainly based on retrospective surgical series. The aim of this study is to describe the actual prevalence of symptoms in PCNs under surveillance. Methods: Patients with PCNs under surveillance observed from 2015 to 2017 were submitted to magnetic resonance imaging (MRI) and a specific interview. An identical survey was carried out on a control population matched for age, sex, and comorbidities in which any pancreatic disease was excluded by MRI. Results: Two groups of 184 individuals were compared. Patients with PCNs have a similar prevalence of abdominal pain when compared to controls (35.2 vs. 28.8, p = 0.2). PCNs in the distal pancreas experienced a significantly increased prevalence of abdominal pain (42.3 vs. 28.8%, p = 0.04), whereas size and presumed connection with the ductal system did not affect the prevalence of abdominal pain. PCNs associated with abdominal pain did not differ in terms of clinical and radiological features from asymptomatic ones. Conclusion: Patients with PCNs under surveillance have a similar prevalence of abdominal pain when compared to a matched population of controls. Abdominal pain might not correlate with radiological signs of malignancy.
