Axial CT image with IV contrast and added color: Cross lines towards top left surround a macrocystic adenocarcinoma of the pancreatic head.
A pancreatic tumor is an abnormal growth in the pancreas. [1] In adults, almost 90% are pancreatic cancer and a few are benign. [1] Pancreatic tumors are rare in children. [1] Classification is based on cellular differentiation (ductal, acinar, neuroendocrine, other) and gross appearance (intraductal, cystic, solid). [1]

Surgery can include the removal of the head of the pancreas (a pancreaticoduodenectomy), removal of the body and tail of the pancreas (a distal pancreatectomy), or rarely removal of the entire pancreas (a total pancreatectomy). [6] In selected cases the surgery can be performed using minimally invasive techniques such as laparoscopy. [7]
Acinar cell carcinoma of the pancreas, also acinar cell carcinoma, is a rare malignant exocrine tumour of the pancreas. It represents 5% of all exocrine tumours of the pancreas, making it the second most common type of pancreatic cancer. [1] It is abbreviated ACC. It typically has a guarded prognosis.
Gastrinoma is the second most common functional pancreatic neuroendocrine tumor (pNET), with a yearly incidence of approximately 0.5 to 21.5 cases per a million of people worldwide. [5] Gastrinomas are located predominantly in the duodenum (70%) and pancreas (25%). [ 20 ]
Anatomically, the pancreas is divided into a head, neck, body, and tail. The pancreas stretches from the inner curvature of the duodenum, where the head surrounds two blood vessels: the superior mesenteric artery and vein. The longest part of the pancreas, the body, stretches across behind the stomach, and the tail of the pancreas ends adjacent ...
The pancreatic duct is generally regarded as abnormally enlarged if being over 3 mm in the head and 2 mm in the body or tail on CT scan. [9] Pancreatic duct or parts of pancreatic duct can be demonstrated on ultrasound in 75 to 85% of people. [10] Pancreatic ductal carcinoma is a common form of pancreatic cancer.
