Subsequent precontrast MRI demonstrated T1 and T2 hyperintense abnormalities in the caudate nucleus portion of the right basal ganglia (Figure 1).
MRI brain postcontrast T1-weighted axial spin echo image. Arrows highlight hyperintense signal abnormalities in the right basal ganglia with no change in enhancement postcontrast.

Postcontrast MRI of the brain showed no abnormal enhancement excluding the possibility of a mass lesion (Figure 2).
MRI brain with diffusion-weighted axial image. Arrows highlight the corresponding right basal ganglia with no hyperintense signal abnormality to suggest ischemia.

Diffusion-weighted MRI brain images did not reveal any abnormal restricted diffusion in the right basal ganglia which excluded ischemia (Figure 3).
