case_images: Moment of triggering and postoperative MRI. Distal interphalangeal joint of the triggering finger (arrow) flexed at pre-symptomatic condition (A). 2 months after the onset of dystonia, distal interphalangeal joint of the triggering finger remained extended due to dystonia at the moment of triggering (B). T1-weighted head MRI on the day of the surgery showing coagulated lesion (arrow) on the left thalamus (C).

case_images: Within two months after the onset of right index finger stiffness, the severity and frequency of the stiffness rapidly progressed, resulting in near-impossible depression of the trigger (Figure 1AB and Video 1). Four months after the onset of her symptoms, the patient underwent stereotactic radiofrequency thermal ablation of the left VO-thalamotomy for focal hand dystonia (Figure 1C).
