A female spayed bearded dragon (Pogona vitticeps) of unknown age presented with a 48 h history of anorexia and lethargy. On presentation, the patient had a black beard, sunken eyes, and a full coelomic cavity on palpation, although no specific thickening or masses were noted. Diagnostic investigations were conducted in the form of radiographs and ultrasonography. The owner elected euthanasia due to deterioration in the patient's condition. Gross and microscopic postmortem examination revealed a torsion and volvulus of the gastrointestinal tract through a rupture in the mesentery, with marked red-black, segmental discoloration to the intestines. Limitations of this study include no further diagnostic tests other than imaging and decision to euthanize hindering the ability to explore surgical correction. To the authors' knowledge, this is the first reported case of intestinal torsion and volvulus through a mesenteric rupture in a bearded dragon.
