Abstract

A 3-year-old cockatiel was presented for evaluation of a buphthalmic right eye (OD). The history included a traumatic event 5 months prior to presentation, and the referring veterinarian diagnosed cataract and secondary glaucoma. Computed tomography of the bird's orbital region revealed a large right orbital soft tissue mass that extended lateral to the orbital rim with obliteration of the globe without bone involvement. There was also no evidence of metastatic disease within the lungs or any abnormalities within the celomic cavity, therefore enucleation was recommended to achieve a histopathologic diagnosis and prognosis, and to palliate the clinical signs. Final diagnosis was malignant intraocular teratoid medulloepithelioma.
