Plain-English summary
A 5-year-old neutered male Beagle mix had been having seizures for five days and had been showing weakness on the right side of his body for one to two months before that. A special imaging test called computed tomography revealed a mass outside the brain that was causing changes to the skull. The dog underwent surgery to remove the mass, which was found to be a meningioma, a type of tumor that can occur in the brain. This case shows that changes to the skull, known as hyperostosis, can also happen in dogs with meningiomas, not just in cats. The treatment involved surgery, which was necessary to address the tumor.
Abstract
A 5-year-old neutered male Beagle mix dog had a 5-day history of generalized tonic-clonic seizures. Before the seizures, the dog had a 1-2-month history of progressive right hemiparesis. In computed tomography images, a presumed extraaxial mass with hyperostosis and destruction of the skull covering the mass were identified. Surgical excision was performed and the histopathologic diagnosis was meningioma. Hyperostosis is frequently associated with feline meningioma, but this report documents that hyperostosis may also occur secondary to meningioma in the dog.
