Plain-English summary
Two adult cats from the same litter were diagnosed with brain tumors called meningiomas. One cat had a tumor near the brainstem and was treated with radiotherapy, while the other had surgery to remove a tumor affecting different parts of the brain. Both cats had a type of meningioma that is generally considered low-grade. This case highlights the possibility of genetic factors contributing to these tumors in cats, which has not been widely reported before.

Abstract
Case summary In this report we describe the occurrence of intracranial meningioma in two adult cats from the same litter. The location of the meningioma varied: one tumour was at the level of the brainstem, and the other was affecting the temporal and piriform lobes. The cat with the brainstem meningioma was treated with radiotherapy and the littermate had a rostrotentorial craniectomy for tumour removal. Both cats had a histopathological diagnosis of grade I meningioma of a predominantly fibrous subtype. Relevance and novel information Cases of familial meningioma in cats have not previously been described in the veterinary literature. However, familial meningioma is well described in humans and it is possible that cases are underestimated in animals. We discuss the possible genetic background and other causes, as well as challenges we may face in veterinary medicine in identifying these associations.
