Plain-English summary
A group of 46 cats with confirmed brain tumors underwent MRI scans to identify the characteristics of different types of tumors. The most common tumor was meningioma, which appeared as ovoid shapes with strong contrast enhancement, while gliomas showed ring enhancement and caused more swelling in the surrounding brain tissue. MRI successfully detected tumors in 98% of the cats, and experienced reviewers could identify the tumor types based on the MRI images about 82% of the time. This study highlights how effective MRI can be in diagnosing brain tumors in cats and understanding their specific types.

Abstract
The purpose of this retrospective study was to determine the magnetic resonance imaging (MRI) characteristics of feline brain tumors and to determine whether these characteristics can be used to accurately predict the histologic diagnosis. MRI scans of 46 cats with histologically confirmed brain tumors were reviewed, including 33 meningiomas, 6 lymphomas, 4 gliomas, 2 olfactory neuroblastomas, and 1 pituitary tumor. MRI features including axial origin, shape, location, signal intensity, contrast enhancement, peritumoral edema, and mass effect were reviewed and characterized for each tumor type. Tumor shape, axial origin, contrast enhancement, and degree of peritumoral edema aided in the identification of tumor type. Meningiomas were always extra-axial and were most often ovoid with marked contrast enhancement and mild peritumoral edema. Gliomas were always intra-axial with ring enhancement and generally caused more peritumoral edema than other tumors. The brain tumor was detected on MRI in 45 (98%) cats. Two blinded independent reviewers correctly identified 82% of all of the tumor types on the basis of MRI appearance alone. Thus, MRI is an excellent diagnostic tool for the detection of brain tumors in cats, and it provides important information to aid in the diagnosis of tumor type.
