Pancreas Pathology Study Notes

A condition where the pancreas doesn't form a single duct, but instead has two separate ducts, leading to abnormal drainage.

A condition where the pancreatic head encircles the duodenum, often associated with duodenal atresia or stenosis.

Pancreatic tissue found outside the pancreas, potentially leading to pancreatitis or tumor formation.

A fluid collection within the pancreas, usually caused by trauma or pancreatitis, lacking an epithelial lining. It can cause peritonitis.

Inflammation of the pancreas caused by the leakage of digestive enzymes into surrounding tissues. It presents with pain, nausea, and fever.

Irreversible damage to the pancreas, often caused by long-term alcohol abuse or biliary disease.

A benign tumor that produces excess insulin, causing hypoglycemia.

A malignant tumor in the pancreas that overproduces gastric acid, leading to Zollinger-Ellison syndrome.

Enzymes escape the pancreatic ducts, causing tissue destruction due to the pancreas's lack of a capsule.

Pain after meals or alcohol consumption, fever, sweating, nausea, vomiting, and gas build-up in the abdomen.

Hypoechoic pancreas with swelling, compression of the inferior vena cava (IVC), and dilation of the pancreatic duct or CBD.

Thick mucus blocks pancreatic ducts, hindering enzyme production. A hyperechoic pancreas with fibrosis, cysts, and calcifications on ultrasound.

A fluid-filled sac within the pancreas.

A slow-growing cystic tumor within the pancreas, arising from ducts and characterized by thick walls.

A malignant tumor of the exocrine pancreas, primarily affecting men.

Jaundice (yellowing of the skin), weight loss, abdominal and back pain, lack of appetite (anorexia), and nausea.

A hyperechoic mass in the pancreatic head with irregular borders and dilated duct on ultrasound.

A hypoechoic, undefined mass with ductal dilation.

A tumor originating from the hormone-producing islet cells of the pancreas.

Biliary disease, alcohol abuse, trauma, drug use, infections (like mumps), and scorpion bites.

Elevated amylase and lipase levels, increased white blood cell count (WBCs), and elevated bilirubin.

Progressive scar tissue development, calcifications, and duct obstruction, often associated with alcohol abuse.

Calcifications, pseudocyst formation, and ductal dilation.

Pseudocysts, common bile duct dilation, and splenic vein thrombosis.

A localized inflammation of the pancreas with edema and necrosis.

A rapid progression of acute pancreatitis with necrosis of pancreatic vessels leading to bleeding.

A hypoechoic, pus-filled mass that can be a complication of acute pancreatitis.

Women have a higher chance of developing cystadenomas.

A disease or a condition with an unknown cause.

Inflammation of the peritoneum, the lining of the abdominal cavity.

Absence or abnormal narrowing of an opening.

The pancreas normally appears bright and uniform due to surrounding fat.

A bruise or discoloration of the skin caused by bleeding under the surface.

Swelling caused by fluid build-up.

The formation or discharge of pus.

Swollen or fluid-filled.

Abdominal pain, nausea, vomiting, abdominal distention, and bruising.
