Pancreatolithiasis and pancreatic pseudobladder associated with pancreatitis in a cat.

Pancreatolithiasis has been documented to occur naturally in humans and cattle. It has been associated with chronic pancreatitis in humans, and, when found, it may signify the presence of chronic pancreatic disease. This is the first report of a case involving a cat that had both an apparent obstruction with pancreatolithiasis as well as concurrent evidence of chronic pancreatic changes on histopathological evaluation. Additionally, this case documents the presence of a suspected congenital abnormality of a feline exocrine pancreas.
