Abstract:
A five-year-old rabbit was evaluated for a 7 to 8 month history of regurgitation, weight loss, and hyporexia. Previously performed whole body radiographs, plasma biochemistry results and complete blood count revealed had no significant abnormalities. A computed tomography (CT) scan revealed a circumferential caudal esophageal thickening. The animal received supportive care until euthanasia was performed 6 weeks later. Caudal esophageal smooth muscle hypertrophy was diagnosed on necropsy. This case indicates that regurgitation can occur in rabbits and advanced imaging can investigate the underlying cause.
