Limy bile syndrome in a dog.

A 11-year-old spayed female golden retriever was examined because of lethargy, anorexia, vomiting and abdominal pain. Plain abdominal radiography showed a uniform radiopacity of the gallbladder. Ultrasonography demonstrated hyperechoic material in the gallbladder lumen associated with an acoustic shadow and findings consistent with acute pancreatitis. Fine-needle aspiration of the bile revealed bacterial cholecystitis. Following cholecystectomy, it was apparent that the gallbladder was filled with a semi-solid, pasty-like greenish-brown material composed of 80% calcium carbonate, consistent with a diagnosis of 'limy bile'. After surgery and medical treatment, the dog's condition improved. Two months after discharge, the dog had fully recovered a good appetite and no relapse has been observed after 11 months of follow-up. To our knowledge, this is the first report of limy bile syndrome in a dog.
