Single-Voxel Proton Magnetic Resonance Spectroscopy Findings at 3 Tesla in a Dog With Gliomatosis Cerebri.

ABSTRACT: Gliomatosis cerebri (GC) represents an antemortem diagnostic challenge in the absence of histopathology. Proton magnetic resonance spectroscopy (1H-MRS) features of the disease in humans include elevated myo-inositol (mI)-to-creatine and decreased N-acetyl-aspartate (NAA)-to-creatine ratios. Brain 1H-MRS findings at 3 Tesla (3 T) field strength in dogs with GC have not yet been described. A 12-year-old West Highland White Terrier was presented with a progressive history of multifocal encephalopathy. A 3 T MRI revealed a diffuse, bilateral, ill-defined, intra-axial white matter lesion that was T2W and FLAIR hyperintense, T1W iso- to hypointense, showed no contrast enhancement, and was associated with moderate mass effect. 1H-MRS with voxel positioning at the left parietal area showed highly
