Idiopathic mesenteric and omental steatitis in a dog

Journal of the American Veterinary Medical Association
Shinobu KomoriTetsushi Yamagami


A 2-year-old Miniature Dachshund was admitted to the hospital because of fever, frequent vomiting, and watery diarrhea. An intra-abdominal mass and a gastric ulcer were detected. At laparotomy, the omentum was yellow but not icteric, irregularly thickened, and fragile, and a large mass involving the root of the mesentery and the gastrosplenic ligament was found. The histopathologic diagnosis was steatitis, and the dog was treated with prednisolone and cyclosporine for 2.5 years. After 1.5 years, the abdominal mass was not detectable. The dog died suddenly from perforation of the small intestine caused by a foreign body. Necropsy revealed severe adhesions between portions of the small intestine, and cicatrization of the mesentery. Cause of the mesenteric and omental steatitis was not apparent.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
