{Abstract}: Ectopic pancreas (EP) is an uncommon, congenital focus of pancreatic tissue that is discontinuous with the principal pancreas. A 62-year-old female underwent multiple investigations for chronic epigastric pain. EP was identified intra-operatively. On retrospection, earlier imaging showed a thickened segment of jejunum with inflammation of the surrounding small bowel mesentery, suggestive of jejunal EP pancreatitis. Histology confirmed ectopic pancreatic tissue, with sections of the EP showing evidence of previous acute and chronic pancreatitis. When no cause for chronic abdominal pain is found, diagnostic laparoscopy should be considered, and the small bowel inspected, to further investigate for rare causes of abdominal pain, such as EP.
