Despite her low education, her former writing abilities were considered to be adequate when evaluated through a letter she had written 5 years before the onset of her symptoms (Figure 1).
Axial susceptibility-weighted image (A) discloses the old thalamic hemorrhage as diffuse hypointensity (arrow). Tractography obtained by placing seeds in the thalamus and the corresponding parietal lobe on each side, encompassing predominantly the posterior thalamic radiations, shows asymmetry, with decreased fibers on the left (dark orange) compared to the right (light purple) (B). Coronal T1-weighted inversion-recovery image (C) demonstrates the atrophy of the left mammillary body (arrow). 99mTc-HMPAO SPECT axial image (D) shows hypoperfusion in the left frontal and parietal cortices.

In addition, there was associated volume loss, which was more evident in a susceptibility-weighted image (Figure 2A). Diffusion tensor imaging revealed an asymmetry between the left and right posterior thalamic radiations (PTRs); specifically, the left PTR was smaller than the right PTR (Figure 2B). In addition, the left mammillary body was smaller than its counterpart in the right hemisphere (Figure 2C).
