Congenital stenosis
Cystic dilation
- Image of chronic pancreatitis with cystic ducts in a horse from Cornell Veterinary Medicine
- Occurs mostly in cats and occasionally in lambs
- The cystic nature of the ducts can be accompanied by cysts in liver and kidneys - polycystic

Sometimes small pieces of pancreatic tissue are seen in diverse places like the submucosa and muscle of nearby alimentary tract, liver, gall bladder, spleen and mesentery
Occurs in dog and cat

-*Occurs in calves, dogs (German Shepherd Dogs are the prevalent breed) and cats
-*Endocrine part of the pancreas seems unaffected
-===Clinical signs===
-*[[EPI|Exocrine pancreatic insufficiency]]
-*Occurs at about one year of age
-*Onset often preceded by another illness
-===Gross appearance===
-*Pot-bellied appearance on external view
-*Intestines are distended by bulky fatty ingesta
-*Lack of fat in the mesentery and rest of the abdomen
-*The pancreas appears extremely thin and almost lace-like, is sparse and pink, easily visible due to lack of fat
-*The hypoplastic pancreas may be inconspicuous at laparotomy or post mortem examination owing to its small size
-===Microscopic appearance===
-*Tiny lobules with glandular cells, some appear to be undergoing regression, hence the alternative view that the [[Pancreas - Anatomy & Physiology|pancreas]] is normal at birth but undergoes progressive regression - [[Pancreas Degenerative - Pathology#Juvenile pancreatic atrophy|juvenile atrophy]]
-*Hypoplastic parenchymal cells do not usually contain lipofuscin, which can be seen in atrophic cells
