Imaging Islet Cell Tumours
نویسنده
چکیده
Islet cell tumours are rare lesions. The majority (85%) are functioning hormone-producing tumours, insulinomas and gastrinomas being the most common. Approximately 15% of islet cell tumours are nonfunctioning. These are usually larger lesions, often presenting at an advanced stage as a pancreatic mass or with metastatic disease. This review will focus on the role of endoscopic ultrasound in the detection of pancreatic islet cell tumours and its complementary role to computed tomography and other imaging techniques. The potential for endoscopic ultrasound-guided biopsy will also be discussed.

Islet cell tumours
Islet cells tumours are a range of rare neoplasms of neuroendocrine origin arising in or close to the pancreas. The normal islet cells of Langerhans in the pancreas contain B-cells (which secrete insulin), A-cells (which secrete glucagon), D-cells (which secrete somatostatin), Dl-cells (which secrete pancreatic polypeptide, PP) and D2-cells (which secrete vasoactive intestinal peptide). The maj...
متن کاملEndoscopic ultrasound in the detection of pancreatic islet cell tumours
The role of endoscopic ultrasound (EUS) in the detection of pancreatic islet cell tumours is reviewed. Functioning islet cell tumours are frequently small at presentation (90%< 2 cm). Advances in cross-sectional imaging with CT and MRI have resulted in improved detection rates of these small lesions. The sensitivity of EUS in the detection of insulinoma is similar to helical or multislice CT, i...
متن کاملEndoscopic ultrasound for localisation of islet cell tumours.
In a prospective study endoscopic ultrasound localisation of pancreatic endocrine tumours was attempted in 21 patients with clinically suspected islet cell tumours. Most patients were referred after the failure of conventional imaging methods. Endoscopic ultrasound correctly identified the site of 12 of 15 insulinomas, one glucagonoma, and a diffuse pancreatic abnormality in a patient with mult...
متن کاملCT/MRI of neuroendocrine tumours
Neuroendocrine tumours (NETs) are often thought to be rare and rather recherché cancers which are of little concern to the general physician, surgeon or radiologist because of their rarity and esoteric nature. In fact, while relatively uncommon, the total group of gastro-entero-pancreatic (GEP) tumours incorporates the spectrum of all types of carcinoids, including bronchial carcinoids, and the...
متن کاملCo-Transplantation of VEGF-Expressing Human Embryonic Stem Cell Derived Mesenchymal Stem Cells to Enhance Islet Revascularization in Diabetic Nude Mice
Background: Pancreatic islet transplantation has emerged as a promising treatment for type I diabetes. However, its efficacy is severely hampered due to poor islet engraftment and revascularization, which have been resulted to partially loss of transplanted islets. It has been shown that local delivery of vascular endothelial growth factor (VEGF) could accelerate transplanted islet revasculari...
