Abstract:
A 1.5-year-old male Siberian Husky dog was presented with a history of progressive twitching and tetraplegia. The dog was humanely destroyed and at necropsy examination an incidental intramural white lesion measuring 10 × 15 × 5 mm was observed in the gallbladder. Histologically, the mass consisted of pancreatic tissue located in the tunica adventitia of the gallbladder. Immunohistochemistry revealed that the islets of Langerhans were positive for insulin, but negative for glucagon. In addition, the dog had non-suppurative meningoencephalitis associated with canine distemper virus infection. The gallbladder lesion was consistent with pancreatic choristoma and is the first case described in a canine gallbladder.

Diseases of the Liver and Gallbladder
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...
Pancreatic Juice and Secretion
When acidic chyme from the stomach enters the duodenum, it triggers the release of secretin, a hormone that prompts pancreatic juice secretion. After a fatty meal, cholecystokinin, another hormone, stimulates gallbladder contraction and enhances enzyme-rich...
Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
