7.0-Tesla Tesla magnetic resonance imaging of granulomatous meningoencephalitis in a Maltese dog: a comparison with 0.2 and 1.5-Tesla

7.0-Tesla Tesla magnetic resonance imaging of granulomatous meningoencephalitis in a Maltese dog: a comparison with 0.2 and 1.5-Tesla

Journal of Veterinary Medical Science 71(11): 1545-1548

A 6-year-old, intact female Maltese dog was presented with generalized seizures. Based on the neurological and physical examinations, intracranial lesion was suspected. Magnetic resonance imaging (MRI) of the brain was performed at three different magnetic field strengths (0.2, 1.5 and 7.0 T). Diffuse hypo- and hyperintense lesions involving the left caudate nucleus and internal capsule to the cranial diencephalon were identified on T2-weighted images. The detailed anatomical locations, the inflammatory and hemorrhagic changes of the lesions could be detected more apparently at 7.0 T. Histopathologically, granulomatous meningoencephalitis (GME) was diagnosed. This is the first case describing histopathologically confirmed GME lesions using 0.2, 1.5 and 7.0 T clinical MR scanner.
