Ruptured jejunal diverticulum in a 7‐month‐old domestic shorthair cat

Abstract

A 7‐month‐old, female, entire, domestic shorthair presented for acute onset vomiting and anorexia for 24 hours. Radiographs were concerning for mineralised foreign body and peritonitis due to decreased serosal detail and mineral opacities not associated with the lumen of the intestines. An abdominal ultrasound confirmed the presence of a mass or foreign body with a scant amount of fluid in the caudal abdomen. A celiotomy was performed revealing a 3 cm diameter mass at the antimesenteric border of the jejunum with adhered omentum to the jejunal wall. Resection and anastomosis were performed, and the cat recovered uneventfully. The mass was found to be a ruptured jejunal diverticulum. To date, there are few congenital diverticula reported in cats, and to the authors’ knowledge, no previous reports of ruptured diverticula in cats.
