FINALS: LONGGGG EXAM Flashcards
abnormal growth or tumor located in
the head of the pancreas, which is the part of the
pancreas closest to the small intestine and bile
duct. This mass can be either benign or
malignant (cancerous).
Pancreatic head mass
head of the pancreas to join the pancreatic duct and
empty at the
ampulla of Vater into the duodenum.
most common type of
pancreatic cancer
* It arises from the ductal cells of the
pancreas and is often aggressive.
* It can invade nearby structures
Pancreatic Adenocarcinoma
originate from the
pancreatic islet cells that produce
hormones.
Pancreatic Neuroendocrine Tumors (NETs)
These are fluid-filled sacs or pockets
that may develop in the pancreas.
Pancreatic Cystic Lesions
These are benign tumors that arise from
the ductal epithelium of the pancreas.
Pancreatic Ductal Adenomas
Lymphomas can occasionally involve the
pancreas, presenting as a mass in the
pancreatic head.
Pancreatic Lymphoma
These are non-neoplastic lesions that
mimic the appearance of a tumor on
imaging but are not composed of
abnormal cells.
Pseudotumors
Some masses in the pancreatic head may
have mixed solid and cystic
components, making their classification
more complex.
Solid and Cystic Masses
The amount of serum bilirubin to show the
yellowing skin tone of a patient with jaundice
≥ 2.5mg/dL of Serum Bilirubin
This is before Bilirubin reaches the Liver
* Increased Unconjugated Bilirubin
Prehepatic/Hemolytic
Damaged Hepatocytes
Hepatocellular/Intrahepatic
Impaired flow of bile into intestines
* The blockage causes pressure to
increase in the bile duct causing bile to
leak through the tight junctions between
the hepatocytes
Post Hepatic/Obstructive
Due to the obstruction on the bile
canaliculus, the bile flows backwards to
the tight junctions in between the
hepatocyte and reaches the blood.
Hypercholesterolemia & Xanthomas
→ HALLMARK SIGN of obstructive jaundice
secondary to pancreatic head mass
Painless jaundice
e GOLD STANDARD for diagnosing obstructive
jaundice secondary to a pancreatic mass
Endoscopic Retrograde Cholangiopancreatography
(ERCP)
