Congenital

 

Traumatic

 

Inflammatory

IgG4-related disease (pancreatic):

The pancreas appears bulky, specifically the pancreatic head and uncinate process, surrounded by minimal peripancreatic fat stranding. Multiple enlarged peripancreatic lymph nodes. The common bile duct appears dilated, with evidence of distal common bile duct wall thickening, and associated intrahepatic biliary tree dilatation

serum IgG4 serum levels are markedly elevated.

***************************************************

Neoplastic

pancreatic adenocarcinoma

can be seen elsewhere in the pancreas (other than the head), rapidly metastasize

***************************************************

Pancreatic neuroendocrine tumour: (CT and MR)

presentation 1: low signal on T1, high signal on T2 with restricted diffusion. The postcontrast sequences show an intense and homogeneous enhancement in the arterial phase, and isointense to the normal pancreatic parenchyma in the portal phase

presentation 2:: heterogeneously enhancing mass in the head of the pancreas with cystic/necrotic changes

further workup: Endoscopic ultrasound with transgastric fine needle aspiration of the mass

***************************************************

Vascular

Haemosuccus pancreaticus

is a rare cause of GI bleeding, due to blood originating from the pancreatic duct into the duodenum via the ampulla of Vater, or major pancreatic papilla.

The most common aetiology is pseudoaneurysm rupture of the splenic (60-65%)1, gastroduodenal or pancreaticoduodenal artery. Pseudoaneurysm formation is most commonly secondary to chronic pancreatitis and occurs in 10% of this population.

Chronic local inflammation is thought to lead to an increased local release of elastase, with either autodigestion of peripancreatic vessels or erosion of a concomitant pseudocyst into the artery

Miscellaneous

Pancreas transplant

A pancreas transplant is a procedure in which a donor pancreas is transplanted to a recipient. The donor pancreas is typically cadaveric, but may rarely be a segment from a living donor. The transplant is meant to establish normoglycemia in patients with diabetes mellitus, typically type 1, though similar outcomes may be achieved with patients with type 2 diabetes mellitus

The most common types of pancreas transplants are :

  • SPK: simultaneous pancreas and kidney transplant (~78% of cases)
  • PAK: pancreas after kidney transplant (~16% of cases)
  • PTA: pancreas transplant alone (~7% of cases)
