“…At GIUS, I-NETs generally appear as nodular submucosal protuberances, hypoechoic, well-defined, predominantly intraluminal. There is sometimes a hyperechoic rim surrounding the lesions and internal calcifications [101][102][103]. The lesion can be a lead point for intussusception.…”

Transabdominal gastrointestinal ultrasound (GIUS) is unique in its capacity to examine the bowel non-invasively and in its physiological condition, including extra-intestinal features such as the splanchnic vessels, mesentery, omentum and lymph nodes- even at the bedside. Despite this, and its extensive documentation for its usefulness, it has only been fully implemented in a few European countries and expert centres. Therefore, the European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB) established a GIUS Task Force Group in 2014 consisting of international experts from 9 European countries with the objectives to standardize and promote the use of GIUS in a clinical setting. This is achieved by publishing clinical guidelines and recommendations on indications and use of GIUS and so far,4 guidelines have been published: first on “examination techniques and normal findings”, second on “inflammatory bowel disease”, third on “acute appendicitis and diverticulitis” and fourth on “transrectal and perineal ultrasound”.This paper describes the ultrasound features of miscellaneous disorders such as celiac disease, cystic fibrosis, omental infarction, Meckel’s diverticle, endometriosis, intestinal neoplasia, mucocele, amyloidosis, GVHD, foreign bodies, vasculitis, and pneumatosis cystoides intestinalis. Bowel ultrasound can be indicated in most of these conditions to investigate intestinal symptoms but in other cases the alterations of the bowel can be also an incidental finding that suggest other examinations which finally help to discover an unknown pathological condition.

“…Neuroendocrine tumours of the pancreas account for 7% of all GEP-NEN and approximately 10% of all pancreatic neoplasms (4) . In recent years an increase in the prevalence of gastric and rectal NEN versus intestinal NEN has been observed (1,5–10) . The NEN detection rate has significantly increased over the last few decades (1,3) .…”

The diagnosis of gastrointestinal neuroendocrine neoplasms represents a significant diagnostic challenge since these tumours have a various, often non-specific clinical presentation. Currently, more than half of gastroenteropancreatic neuroendocrine neoplasms are detected incidentally, usually during surgery, diagnostic imaging studies or endoscopic procedures performed for other indications. Sometimes the first symptom of the disease is the presence of metastatic lesions in the liver. A neuroendocrine tumour is diagnosed based on the clinical presentation, assessment of specific and non-specific biochemical markers, imaging studies and histopathological examination. Focal lesions, both primary and metastatic may be small and often have an atypical location. Diagnostic imaging of neuroendocrine tumours is of fundamental importance for determining the location of the primary lesion, staging of the disease, selection of treatment and monitoring of its effects. In addition, diagnostic imaging make it possible not only to detect tumours, but also to perform therapeutic procedures based on the result. Transabdominal ultrasound is one of the first diagnostic imaging method for neuroendocrine neoplasms. New ultrasound techniques such as ultrasound elastography, contrast-enhanced ultrasound, endoscopic ultrasound, intraductal and intraoperative ultrasound improve the efficacy of ultrasound examination. Endoscopic ultrasound is a fundamental diagnostic tool for the detection of neuroendocrine tumours of the pancreas and the distal part of the colon. Due to the large variety of neuroendocrine tumours and differences in tumour biology, clinical stage and expression of somatostatin receptors, no single imaging method is sufficient; therefore, in order to determine the right diagnosis and select the best treatment, it is recommended that a combined morphological and functional assessment be used.
