Question of the Day
A 12-year-old miniature horse stallion is presented for inappetance and strange behavior. He typically lives in a pasture with a herd of seven other horses, including mares and foals, supplemented with round bales of grass hay.
Five days prior to presentation he had his feet trimmed and was subsequently very sore so was kept indoors, away from the herd, on 2.2 mg/kg of phenylbutazone once daily.
On examination he is head-pressing and obtunded. During the exam he goes down and has a seizure, and is then euthanized.
At necropsy the liver looks like the image below.
What histopathological finding is most likely to be described from this liver?
