Clinical Clues

  5. Imaging supports concurrent pancreatic, intestinal, and biliary inflammation.
  6. This combined inflammatory syndrome is known as feline triaditis.

Diagnosis

Feline Triaditis

This case is most consistent with Feline Triaditis because the cat has simultaneous pancreatic, intestinal, and hepatobiliary abnormalities with a compatible clinical picture. The most important clues are the jaundice, abdominal pain, and multi-organ ultrasound changes, which make a single isolated GI disorder less likely.
