title: [Intraocular osteosarcoma in a dog].
abstract: The present case describes the diagnostic and therapeutic procedure of a dog with an intraocular osteosarcoma. According to the results of the diagnostic imaging studies, the tentative diagnosis of an intraocular neoplasm with perforation of the globe and orbital invasion of the tumour was made and an orbital exenteration was performed. The histopathological diagnosis of the extracted organ implied an intraocular, extraskeletal osteosarcoma. Seventy-seven days later the patient displayed an acute paraparesis. Clinical and diagnostic reevaluation using magnetic resonance imaging (MRI) was performed and the dog was euthanized at the owner's request. By means of MRI and necropsy, an additional axial osteosarcoma of the 6th lumbar vertebra and a malignant melanoma of the right tonsil were diagnosed.
