case_images: (a) Before treatment, the wall of the left temporal artery of the patient has obvious thickening, and the cross-section of the blood vessel shows a hypoechoic halo and (b) the left thyroid parenchyma of the patient is diffusely reduced and uneven, and the parenchyma is rich in blood supply.

case_images: The temporal vessels revealed coarse and thickened (0.05 cm) intima of both temporal arteries and a halo in the transverse plane (Figure 1(a)). A nodule with regular margins was evident in the upper pole of the left lobe of thyroid (Figure 1(b)).
case_images: (a) The patient's left temporal artery trunk cross-section can be seen by ultrasound, the wall is thin (arrow) and the original halo sign disappeared and (b) the long-axis section of the left lobe of thyroid was seen through ultrasound, showing that the original obviously low and uneven echo changed to moderate echo.

case_images: The other vessels had not been affected by treatment (Figure 2(a)). Moreover, B-mode US of the long-axis section of the left lobe of thyroid revealed that the low and uneven echoes had become moderate (Figure 2(b)).
