Plain-English summary
A 6-year-old mixed breed dog was diagnosed with a meningeal osteosarcoma, a type of bone cancer affecting the protective membranes of the brain. The dog showed neurological symptoms, likely due to a mass pressing on the brain. This tumor was found attached to the cerebellum and was made up of abnormal cells. Unfortunately, the details of treatment and outcome were not provided, but this case is significant as it is the first reported instance of this type of tumor in a pet.

Abstract
A meningeal osteosarcoma was diagnosed in a dog displaying neurologic signs compatible with a space-occupying cerebellar lesion. Gross lesions, restricted to the brain, consisted of a solitary, compressive mass attached to the dura mater overlying the left cerebellum. The mass was composed of single and multinucleated, atypical polygonal cells that lined or rested within lacuna surrounded by eosinophilic, mineralized matrix. The matrical component stained dark green-yellow to blue with Movat's pentachrome stain, deep blue to red with Heidenhain aniline blue stain, and brown-black with Von Kossa stain. Results of these stains were interpreted as tumor osteoid. Foci of dural mineralization and osseous metaplasia were present at the point of tumor attachment. The microscopic observations were interpreted as an osteosarcoma of extraskeletal origin. To our knowledge, these findings represent the first documented case of a meningeal osteosarcoma in a domestic animal species.
