Cerebellar Focal Granulomatous Meningoencephalitis in a Dog: Clinical Findings and MR Imaging

Abstract

The authors encountered a dachshund dog, presenting vestibular disorder. On magnetic resonance (MR) imaging, a mass showing isointensity on the T1‐ and T2‐weighted images and enhanced by contrast medium, was observed in the right cerebellum. In addition, the periphery of the mass showed isointensity on the T1‐weighted image and hyperintensity on the T2‐weighted image, suggesting sever oedema. Although the dog underwent surgery, it died. The mass was diagnosed pathologically as a granulomatous meningoencephalitis.
