case_images: (A) Clinical timeline of patient's procedures and DBS programming parameters following FUS and lead implantation. The patient's tremor was evaluated using the Clinical Rating Scale for Tremor (CRST) A subsection, which evaluates tremor, including those of the upper extremities. (B) "Archimedes spiral" drawings (right hand only) during the B subsection of the CRST assessment to evaluate hand tremor at each time point to demonstrate tremor progression over time after MRgFUS procedure. Spiral A is wide, compared to the narrow spiral B (acquired as part of the CRST B).

case_images: Her handwriting as well as her straight line and spiral drawing tests were markedly abnormal (Figure 1). The CRST A subscore was 30 at the time of presentation in 2015, reflecting her postural and kinetic tremors (Figure 1). At her last evaluation (16-month follow-up after DBS), she had consistent and effective tremor control, with a CRST score of 7 (Figure 1).
