Chronologic changes in striatal lesions
| A: Progression pattern of striatal lesions* | ||
|---|---|---|
| Lesion | Initial Diffusion-weighted Imaging Study | Latest Diffusion-weighted Imaging Study |
| Asymmetric | 4 (50) | 1 (12) |
| Symmetric | 4 (50) | 7 (88) |
| B: Relationship between lesions† | ||
|---|---|---|
| Caudate Head Lesion | Initial Diffusion-weighted Imaging Study | Latest Diffusion-weighted Imaging Study |
| Without ipsilateral putaminal lesion | 4 | 0 |
| With ipsilateral putaminal lesion | 11 | 15 |
Note.—The evaluation of chronologic changes involved data from eight patients with striatal lesions who were examined with diffusion-weighted imaging more than twice.
* Data are the number of patients (n = 8). Data in parentheses are percentages.
† Data are the number of caudate head lesions with or without ipsilateral putaminal lesion.
