Background & Aims: Diagnosis of pancreatic neuroendocrine tumors (p-NETs) is frequently challenging. We describe a large series of patients with p-NETs in whom both pre-operative Computed Tomography (CT) and Endoscopic Ultrasonography (EUS) were performed. Methods: This was a retrospective analysis of prospectively collected sporadic p-NET cases. All patients underwent both standard multidetector CT study and EUS with fine-needle aspiration (FNA). The final histological diagnosis was achieved on a post-surgical specimen. Chromogranin A (CgA) levels were measured. Results: A total of 80 patients (mean age: 58 ± 14.2 years; males: 42) were enrolled. The diameter of functioning was significantly lower than that of non-functioning p-NETs (11.2 ± 8.5 mm vs 19.8 ± 12.2 mm; P = 0.0004). The CgA levels were more frequently elevated in non-functioning than functioning pNET patients (71.4% vs 46.9%; P = 0.049). Overall, the CT study detected the lesion in 51 (63.7%) cases, being negative in 26 (68.4%) patients with a tumor ≤10 mm, and in a further 3 (15%) cases with a tumor diameter ≤20 mm. CT overlooked the pancreatic lesion more frequently in patients with functioning than non-functioning p-NETs (46.5% vs 24.3%; P = 0.002). EUS allowed a more precise pre-operative tumor measurement, with an overall incorrect dimension in only 9 (11.2%) patients. Of note, the EUS-guided FNA suspected the neuroendocrine nature of tumor in all cases. Conclusions: Data of this large case series would suggest that the EUS should be included in the diagnostic work-up in all patients with a suspected p-NET, even when the CT study was negative for a primary lesion in the pancreas.– .

Endoscopic ultrasonography (EUS) is a versatile tool that can be used to perform a variety of diagnostic and therapeutic procedures in the upper or lower gastrointestinal tract. The proximity of the echoendoscope to the pancreas, liver, and other thoracic and abdominal organs allows detailed examination or minimally invasive intervention that would not be feasible by surgical or percutaneous approaches. EUS is available with radial or linear scanning arrays and is capable of guiding fine-needle aspiration to acquire tissue for cytologic analysis. This review covers the role of EUS in chronic pancreatitis; pancreatic cysts; submucosal tumors; suspected choledocholithiasis; fecal incontinence; staging of malignancy in esophageal, pancreatic, gastric, and rectal cancer; celiac plexus block/neurolysis; fiducial placement; pseudocyst drainage and cystogastrostomy/cystoduodenostomy; endoscopic necrosectomy; and biliary drainage. Figures show peripancreatic cysts, gastrointestinal stromal tumor, common bile duct stone, esophageal adenocarcinoma, pancreatic head mass causing biliary obstruction and invading portal confluence, fine-needle aspiration of a pancreatic head mass, rectal adenocarcinoma, abdominal aorta with celiac artery and superior mesenteric artery, celiac plexus neurolysis, necrosectomy, and EUS-guided choledochoduodenostomy for failed endoscopic retrograde cholangiopancreatography. Tables list the Rosemont criteria for chronic pancreatitis and pancreatic cystic lesions.   Key words: bile duct stone, biliary drainage, echoendoscope, endoscopic ultrasonography, fine-needle aspiration, pancreatic cyst   This review contains 12 highly rendered figures, 2 tables, and 62 references.

Background: Mass-Forming Chronic Pancreatitis (MFCP) is rare. Moreover, atypical MFCP is difficult to differentiate from Pancreatic Carcinoma (PC) in clinical manifestations, laboratory, and imaging examinations. Diagnosis could be supported by the pathological findings of focal inflammatory fibrosis without evidence of tumor in the pancreas. Case summary: A 52-year-old man had acute pancreatitis twice over 7 months. Amylase and lipase levels were three times higher than the normal range without any clinical symptoms. At the 6th month, the patient lost 15 kg of weight, and abdominal ultrasonography revealed pancreatic head space occupied. All the findings in multimodal imaging including computed tomography image, Magnetic Resonance (MR) imaging with MR cholangiopancreatography, and 18F-FDG positron emission tomography/computed tomography showed an irregular nodule with low density, low signal, and low echo in the head of the pancreas, which were lower than those in the normal pancreatic tissue. The proximal main pancreatic duct was truncated and stenosed, and the distal duct was dilated. Subsequently, he developed progressive painless jaundice, and the specific tumor marker levels were increased. Most of these manifestations were suggestive of the pancreatic malignant tumor; however, multiple specimen pathological findings obtained from laparotomy and endoscopic ultrasonography-guided fine-needle aspiration revealed focal chronic inflammation, fibrosis, and necrosis. Conclusion: This report describes a case of atypical MFCP mimicking PC at clinical presentation and laboratory findings, especially in multimodal imaging. However, the combination of atypical multimodal imaging features, which support MFCP rather than PC, and endoscopic ultrasonography-guided fine-needle aspiration are useful for improving the diagnostic rate of atypical MFCP and avoiding unnecessary surgery.
