Plain-English summary
An adult female Umbrella Cockatoo was brought in after experiencing severe bleeding from her eye due to a mass that had pushed through the cornea. Imaging showed a large tumor in the eye socket, which was later identified as osteosarcoma (a type of bone cancer) after surgery to remove it. The bird received radiation therapy over several weeks and initially recovered well. Unfortunately, she developed neurological signs and passed away two months after completing treatment. This case is notable as it represents the first reported instance of intraocular osteosarcoma in a bird and the use of surgery and radiation therapy for treatment.

Abstract
AbstractAn 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.
