Intermittent Colic and Intussusception Due to a Cecal Polyp in a Rabbit

A 9-year-old male rabbit was presented for chronic intermittent anorexia and colic. A small abdominal mass was evident on palpation, and ultrasonography demonstrated a luminal mass and small intussusception in the distal cecum. Surgical resection of the distal third of the cecum was performed and histologic examination yielded a diagnosis of an inflammatory fibroid polyp. Although reported as causing intussusception in humans and other animals, the authors are unaware of any reports in pet or laboratory rabbits. The etiology and histogenesis of inflammatory fibroid polyps are still unclear.
