Periampullary tumours

Dr Yuranga Weerakkody et al.

Periampullary tumours are those that arise within 2 cm of the ampulla of Vater in the duodenum

Tumours that fall under this group includes four main types of tumours ^1,4

pancreatic head / uncinate process tumours - includes pancreatic ductal adenocarcinoma involving head and uncinate process of the pancreas
lower common bile duct tumours - includes types of cholangiocarcinoma involving the intra-pancreatic distal bile duct
ampullary tumours - those originating from the ampulla of Vater itself
periampullary duodenal carcinoma

Although patients with periampullary tumors have similar symptoms at presentation, they exhibit different clinical outcomes according to the origin of these tumours.

Radiographic features

Their origins are difficult and often impossible to discern based on clinical settings and on pre-operative imaging. The presence of a bulging papilla sign may suggest towards the diagnosis.
