Imaging neuroendocrine tumours of the gastrointestinal tract

Show Summary Details


Gastroenteropancreatic (GEP) tumours are best divided into two distinct groups when discussing their radiological imaging. First are the functioning insulinomas and gastrinomas, which are often small at presentation; imaging of these lesions is usually aimed at localization of the primary tumour (and exclusion of metastatic disease) with a view to surgical excision. Second are the nonfunctioning neoplasms and the functioning tumours—carcinoids being the most common—which secrete a variety of other hormones including glucagon, vasoactive intestinal polypeptide, 5-hydroxytryptamine, somatostatin, serotonin, and pancreatic polypeptide. These are often large at presentation and are, therefore, obvious on cross-sectional imaging studies or have already metastasized; the role of the radiologist in this group is usually that of documenting the extent of disease to guide operative or nonoperative therapy. These two groups will be discussed separately.
