An atypical case of proventricular dilatation in a Red-and-green Macaw (Ara Chloropterus)

Abstract
A Red-and-green Macaw (Ara chloropterus) was presented with regurgitation and passage of undigested seeds in the feces. Radiographic examination revealed dilatation of the proventriculus. Contrast radiography was performed and revealed that the proventricular dilatation and associated clinical signs resulted from circumferential thickening of the proventricular wall leading to severe narrowing of the lumen of the proventriculus. Testing for parrot bornavirus (PaBV) was negative. After the initiation of antimicrobial treatment because of suspected bacterial overgrowth, all clinical signs resolved two weeks after the start of the treatment, and radiographs taken four months after initial presentation revealed a normal appearance and size of the proventriculus. In the present case, bacterial proventriculitis associated with hyperplasia of the proventricular wall was put forward as a final but presumptive diagnosis highlighting the need to differentiate bacterial proventriculitis from other causes of proventricular dilatation in macaws.
