Plain-English summary
A 10-year-old female yellow-naped Amazon parrot was brought to the vet due to symptoms like anemia, weight loss, and regurgitation. Tests showed thickening of the intestines and a type of cancer called diffuse intestinal T-cell lymphosarcoma. The parrot was treated with a chemotherapy plan, but unfortunately, it did not help. Sadly, the decision was made to euthanize her, and the cancer was confirmed during a post-mortem examination.

Abstract
A 10-year-old, intact, female yellow-naped Amazon parrot ( Amazona ochrocephala auropalliata) was examined because of anemia, lymphocytic leukocytosis, regurgitation, and weight loss. A positive fecal occult blood and monoclonal globulinopathy were present. A distended proventriculus and diffusely thickened loops of small intestine with irregular luminal surfaces were identified with contrast radiography and contrast computed tomography. A micro positron emission tomography scan was performed with 18 F-fluorodeoxyglucose. Diffuse intestinal T-cell lymphosarcoma was diagnosed based on histopathology and immunohistochemistry of full thickness small intestinal biopsies. The patient was treated with a multidrug chemotherapy protocol with little to no effect. Euthanasia was elected, and intestinal lymphosarcoma was confirmed on histopathology of necropsy intestinal samples; no other organs demonstrated neoplastic infiltration. To the authors' knowledge, no reports are currently available detailing the clinical presentation or diagnosis of diffuse intestinal T-cell lymphosarcoma in any avian species.
