annular pancreas is a rare congenital condition of the pancreas where the pancreatic tissue either partially or completely covers the duodenum by forming a ring. endoscopic ultrasound is rarely considered as the first diagnosis tool for annular pancreas. we here present a 48 years old man who was primarily provisionally diagnosed with pancreatic mass and was planned for pancreatoduodenectomy. b...

abstract annular pancreas (ap) is a rare congenital malformation resulting from failure of pancreas ventral anlage rotation with the duodenum. this leads to a ring of pancreatic tissue that envelops the duodenum. clinical manifestations of ap most commonly develop in infancy or early childhood but can present at any age. the diagnosis of ap, usually suggested by an upper gi series or abdominal ...

annular pancreas (ap) is a rare congenital abnormality in which pancreatic tissue completely surround the duodenum. presentation of ap in adulthood is very rare and obstructive jaundice is one of the uncommon manifestations of ap in adults. herein; we reported a 47 years old woman who presented with icterus, midcommon bile duct stricture and annular pancreas. she was diagnosed as pancreas cance...

A Study of Annular Slurry Jet for Abrasive Waterjet Cutting

The annular pancreas is a rare congenital anomaly in which a ring of the pancreas parenchyma surrounds the second part of the duodenum. Malignant tumors are extremely rare in patients with an annular pancreas. A 64-year-old man presented with appetite loss and vomiting. Abdominal contrast-enhanced computed tomography (CT) indicated pancreas parenchyma surrounding the second part of the duodenum...

OBJECTIVES Annular pancreas is a rare congenital anomaly characterized by pancreatic tissues wrapping completely or incompletely around the descending duodenum. In most patients with annular pancreas, onset occurs in early childhood. Adults with annular pancreas are prone to duodenal ulcers and pancreatitis. Intraductal papillary mucinous neoplasm (IPMN) is a type of papillary mucinous secretor...

Annular pancreas can present in adult life, usually when inflammation of the pancreatic ring causes duodenal stenosis. Although peptic ulcer is often associated with annular pancreas, an association with gastric carcinoma has not been previously described. Here we report a patient with annular pancreas, chronic alcoholic pancreatitis and gastric carcinoma, who was successfully treated by radica...

Objective: To describe the prevalence of and findings associated with annular pancreas on CT, MRI, and endoscopic retrograde cholangiopancreatography (ERCP). Design: Retrospective analysis. Participants: 42 patients with annular pancreas who underwent CT, MRI, or ERCP made up the study group. The control group consisted of 30 patients evaluated for nonspecific upper abdominal pain who had a nor...
