Magnetic Resonance Imaging Lesions in the Central Nervous System of a Dog with Canine Monocytic Ehrlichiosis
Figure 2
T2-weighted (a) TR = 3500, TE = 90), T1-weighted precontrast (b) TR = 588, TE = 15), and T1-weighted postcontrast (c) TR = 588, TE = 15) transverse plane images at the level of the thalamus in a dog with monocytic ehrlichial meningoencephalitis. A punctate T2 hyperintense lesion in the left dorsal aspect of the thalamus corresponds to a small cavitated region seen on T1-weighted images (white arrows). There is very subtle T1 hyperintensity of brain surrounding the cavitated region. There is little or no contrast enhancement of this lesion.
