Figure 5.
Evolution pattern of an increasing white matter lesion and an increasing contrast enhanced lesion. (A) Post-contrast coronal T1-weighted image shows a solid enhanced nodular lesion in the right temporal lobe. (B) Axial T2-weighted image shows a local white matter lesion in the right temporal lobe. (C-F) In the following two magnetic resonance imaging examinations, the contrast enhanced lesion extended successively, accompanied by extending of the white matter lesion. (C) The contrast enhanced lesion in the right temporal lobe extended to form an enhanced nodular lesion with a necrotic center. (D) The local white matter lesion in the right temporal lobe extended to form a moderate white matter lesion. (E) The enhanced nodular lesion with a necrotic center in the right temporal lobe continued to extend to be a larger size. (F) The moderate white matter lesion in the right temporal lobe extended to form a diffuse white matter lesion.
