Pancreas & Gallbladder Flashcards
which pancreatic disease is characterized by indistinct margins, red/swollen parenchyma, edema, fat necrosis/saponification, yellow/white or tan chalky plaque areas
acute pancreatic necrosis
which pancreatic disease is characterized by firm, small and nodular and atrophy, fibrosis, lymphocytic or lymphoplasmacytic inflammation
chronic pancreatitis
which pancreatic disease is characterized by fibrin, loss of cellular detail, interstitial hemorrhage and edema, sheets of neutrophils
acute pancreatic necrosis
chronic pancreatitis more common in what species?
cats
acute pancreatic necrosis more common in what species?
dogs
what anatomical difference predisposes cats to chronic pancreatitis and triaditis
merging of common bile duct and pancreatic duct at duodenal papilla
components of triaditis
enteritis (IBD)
pancreatitis
cholangitis/cholangiohepatitis
what is the cause of EPI in young dogs, primarily german shepherds and causes atrophy and replacement fibrosis
canine juvenile pancreatic atrophy
common signs of EPI, what it can lead to and how to diagnose it
weight loss, poor coat, muscle atrophy, pale, soft voluminous & malodourous stool “cow patty”
mesenteric torsion, intussusception
TLI < 2.5 dogs, < 8 cats
common postmortem findings of EPI
interstitial hemorrhage
autolysis
systemic consequences of acute pancreatic necrosis
EPI
cytokine storms = systemic inflam response syndrome (DIC and acute resp distress syndrome)
necrotizing panniculitis
what pancreatic neoplasm is characterized by a tan, white firm multi-nodular, infiltrative, acini/islands/cords, zymogen granules surrounded by dense stroma = desmoplasia/scirrhous response
exocrine
adenocarcinoma
what pancreatic neoplasm is characterized by a benign, discrete encapsulated, fibrous capsule
exocrine adenoma
what pancreatic neoplasm is characterized by variably discrete tan-red masses, lobules and packets of polygonal cells separated by fine connective tissue and cause hypoglycemia
islet cell tumors (insulinoma most common)
most malignant except in ferrets
which nodular lesion of the liver?
dogs 6+ years
not a result of hepatic dysfunction
multiple, 0.5-3 cm
well demarcated
compress adjacent parenchyma
elements of normal liver & cytoplasmic lipid or glycogen
nodular hyperplasia
which nodular lesion of the liver?
true liver disease, hepatocellular loss, fibrosis tracts
nodular regeneration
what differential of nodular lesions of the liver is characterized by a single, compress adjacent tissue, variable size, unencapsulated
hepatocellular adenoma
what differential of nodular lesions of the liver is characterized by solitary, involve entire lobe, well demarcated, friable, more pale, divided into lobules, irregular trabeculae three or more cells thick multiple patterns, distant metastasis uncommon
hepatocellular carcinoma
dogs three syndromes of a hepatocellular carcinoma
- solitary or massive
- multifocal
- diffuse
what differential of nodular lesions of the liver is characterized by neuroendocrine cells within biliary epithelium, single or multiple nodules
hepatic carcinoids
what differential of nodular lesions of the liver is characterized by tumors on skin, spleen and heart
hemangiosarcoma
what differential of nodular lesions of the liver is characterized by hepatic involvement with absence of peripheral lymphadenopathy
hepatosplenic and hepatotropic t cell lymphoma
developmental abnormalities of gallbladder
Bilobed or trilobed gallbladders
biliary atresia
causes of cholecystitis
rift valley fever
infectious canine hepatitis
bacteria from blood and intestine
