Plain-English summary
A 9-year-old mixed-breed dog was diagnosed with a brain tumor after showing signs of neurological issues. Imaging tests revealed a mass in the brain that was linked to a type of skin cancer called lymphoma. The tumor was located outside the brain tissue and had unclear edges on the scans. Unfortunately, the dog’s condition was serious due to the cancer spreading to the brain, and treatment options would depend on the overall health of the dog and the extent of the disease.

Abstract
We describe histopathologically confirmed intracranial metastasis of cutaneous lymphoma. In magnetic resonance (MR) images there was a heterogeneous, contrast-enhancing, extraaxial mass in the right parietal and piriform lobes at the level of the optic chiasm. Our MR imaging findings are consistent with reports in humans in that lymphoma masses have indistinct borders that are iso- to hyperintense relative to adjacent gray matter on T2-weighted images. Our report varies from findings in humans in that the mass was extraaxial, whereas masses reported in humans are intraaxial. Contrast enhancement can be heterogeneous, as in our report, or homogeneous.
