Figure 1. Measurement of the width and length of the anterior limb of the internal capsule on magnetic resonance imaging (MRI). (A&B) On the axial plane of MRI, the width of the anterior limb of the internal capsule was shown. On the axial plane, the width of the anterior limb of the internal capsule was 2.4 mm–2.8 mm In one patient (A) and 3.7 mm–3.8 mm in another patient (B). (C&D) On the coronal plane of MRI, the length of the anterior limb of the internal capsule was shown. The length of the anterior limb of the internal capsule was 14.3 mm–15.2 mm in one patient (C) and 17.2 mm–18.4 mm in another patient (D).
Figure 2. Radiofrequency thermocoagulation in the anterior limbs of internal capsule. (A) The angle of anterior limbs of the internal capsule was shown for location of thermocoagulation. (B) Radiofrequency thermocoagulation was performed in the anterior limbs of internal capsule. (C&D) Eight days after the thermocoagulation, the thermocoagulation lesions were shown in the anterior limbs of the internal capsules.
