Plain-English summary
A 12-year-old cat was brought in with signs of neurological issues due to a brain tumor called a meningioma, which was causing abnormal bone growth in the skull. Imaging tests showed that the tumor was pushing into the skull, leaving only a thin layer of bone intact. The veterinarian performed surgery to remove the tumor and the affected bone, which led to a significant improvement in the cat's symptoms. After five months, there were no signs of the tumor returning, and the cat was doing well.

Abstract
Skull hyperostosis is a frequently recognised feature of meningioma in feline and human patients, occurring at a frequency of around 4.5% of human cases. Evidence of osteolysis with extension of meningioma into, and in some cases through, the region of skull hyperostosis is much less commonly described in human patients. Here we present a 12-year-old cat with marked skull hyperostosis secondary to an intracranial meningioma, with magnetic resonance imaging and computed tomography evidence of tumour extension into the skull, centrally within the region of hyperostosis. Only a thin layer of bone was remaining between the mass and the extracranial region. Surgical resection of the region of skull demonstrating tumour invasion and the underlying mass resulted in good resolution of clinical signs and no post-surgical recurrence of meningioma within the 5 months follow-up period. Histopathological examination confirmed the mass to be fibroblastic meningioma.
