X-ray computed tomography of brain tumors in cats.

X-ray computed tomography (CT) was used to depict intracranial space-occupying lesions in 5 cats. Computed tomographic findings were confirmed by surgical biopsy in 2 cases and at necropsy in 3 cases. The detailed anatomic information provided by CT scans facilitated surgical removal of a brain tumor in 2 cats, and allowed accurate tumor localization and dose optimization for radiation therapy in 1 cat. It was concluded that CT provides information required for accurate diagnosis and treatment of feline brain tumors.
