Abstract

A geriatric male great horned owl (Bubo virginianus) that was a resident at a raptor center was presented for examination because of stridor and weight loss. Results of physical examination, diagnostic imaging, and biopsy were consistent with disseminated lymphoma involving the oropharynx, neck region (including thyroid and parathyroid glands), keel, spleen, and liver. Attempts to treat the owl with chlorambucil failed, and the owl was euthanatized 5 months later. Neoplastic cells from this owl were immunoreactive to CD-3 antibody, suggesting the lymphoma was of T-cell origin.
