case_images: (A) Before treatment: left temporal artery ultrasonography features before steroid therapy showed a hypoechogenic halo of the temporal artery >0.5 mm in thickness. (B) Before treatment: left temporal artery ultrasonography features before steroid therapy showed a hypoechogenic halo of the temporal artery in longitudinal (left) and transverse (right) view (B-mode ultrasound).. Abbreviation: B-mode, brightness-mode.

case_images: We found a hypoechogenic halo of the left temporal artery >0.5 mm in thickness (Figure 1A and B).
case_images: Before treatment, left temporal artery color duplex ultrasonography features before steroid therapy showed a hypoechogenic halo of the temporal artery and the presence of turbulent flow; longitudinal (left) and transverse (right) view.

case_images: Moreover, left temporal artery Doppler signal showed the presence of turbulent flow (Figure 2).
case_images: Posttreatment left temporal artery color duplex ultrasonography, transverse (left) and longitudinal (right) view, showed disappearance of hypoechogenic halo of the temporal artery and of turbulent flow; longitudinal and transverse view, respectively.

case_images: As seen in Figure 3, the halo sign and the turbulent flow disappeared (left temporal artery).
case_images: (A) In the left side: before treatment, longitudinal view of right temporal artery CDU features before steroid therapy showed a hypoechogenic halo of the temporal artery and the presence of turbulent flow and weak flow because of the presence of halo sign corresponding to edema of artery wall (measured ~9 mm superior edema wall's thickness and 8.2 mm inferior edema wall's thickness). (B) Posttreatment, longitudinal and transverse view, respectively, of right temporal artery CDU showed reduction of halo sign and turbulent flow and a stronger flow than before treatment that corresponds to a significant reduction of edema of artery wall (measured ~0.45 mm superior edema wall's thickness and 0.3 mm inferior edema wall's thickness).. Abbreviation: CDU, color duplex ultrasonography.

case_images: The right temporal artery showed a marked reduction of halo sign, as seen in Figure 4A (before treatment) and B (after 7 days of treatment).
