case_images: Based on the characteristic findings of dystonia, such as sensory tricks and early morning effect, cervical dystonia was diagnosed [Figure 1a and Video 1]. At 3 months postoperatively, neck pain had also improved, and the TWSTRS score was 0 points [Figure 1b]. 123I-IMP-SPECT showed reduced cerebral blood flow of extensive bilateral hemispheres from preoperative [Figure 2a] to 3 months postoperatively [Figure 2b].
case_images: Pre- and post-operative cerebral blood flow (123I-IMP-SPECT), 123IMP-SPECT showed reduced cerebral blood flow of extensive bilateral hemispheres from preoperative (a) to 3 months postoperatively (b).
