Plain-English summary
An adult female Umbrella Cockatoo was brought in with bleeding from her eye due to a large mass inside her eye socket that had broken through the cornea. Imaging showed the mass was invading the area around her eye but hadn’t spread to the bone or brain. The veterinarians performed surgery to remove the mass, which was found to be osteosarcoma (a type of bone cancer), and treated her with radiation therapy over six weeks. Although she initially recovered well, she sadly passed away two months later with neurological signs.

Abstract
An adult, presumed intact female Umbrella Cockatoo (Cacatua alba), presented with acute hemorrhage from an intraocular mass that perforated through the right cornea. Computed tomography scanning revealed a large soft tissue mass in the right orbit, invading and displacing the globe laterally, and destroying the scleral ossicles. There was no evidence of bony changes of the orbit or extension of the mass into the optic nerve or brain. Exenteration and mass removal were performed, and osteosarcoma was diagnosed via histopathology. Radiotherapy was delivered with an orthovoltage unit to a total dose of 68 Gray delivered in 17 fractions over 6 weeks. The bird recovered well from treatment, but died 2 months after the last radiation session with neurological signs. Necropsy was not performed. To our knowledge, this is the first case of an intraocular osteosarcoma reported in a bird, and the first case of attempted treatment of osteosarcoma in a bird by a combination of surgery and radiation therapy.
