Plain-English summary
A 13-year-old neutered male cat was brought in after showing changes in behavior for a year, along with signs of a brain issue. An MRI revealed a mass on the right side of his brain that was pushing into the skull and expanding outside of it. The veterinarians performed surgery to remove the tumor, and the cat recovered well. A follow-up after a year showed he had no lasting neurological problems, and the tumor was identified as a grade 1 meningioma, which is a type of brain tumor.

Abstract
Meningioma is the most frequently observed primary brain tumour in cats. Usually, it is associated with an intracranial expansion with consequent brain compression, oedema and brain herniation. Typical features of feline intracranial meningiomas are hyperostosis of the adjacent bone and intratumoral mineralisation. We describe a 13-year-old male neutered cat with a 1-year history of behavioural change. At clinical and neurological examination the cat showed signs consistent with right-sided forebrain lesion. Magnetic resonance images showed a right-sided extra-axial contrast enhancing mass in the region of the frontotemporal lobe. The overlying bone of the calvarium showed a marked defect with extracranial expansion of the tissue. Surgery was performed and the tumour could be exposed by a right-sided temporal approach. After extension of the bony defect the mass could be removed properly. The cat recovered well from surgery and a 12-month follow-up showed no persistent neurological deficits. Histopathological assessment of the tumour revealed a transitional grade 1 meningioma. Despite osteolysis and extracranial expansion of the tumour differentials should include menigioma in feline intracranial neoplasms.
