Fig. 2. The left image (A) shows the patient and symptomatic area from a longitudinal transducer position. Color Doppler sonogram (B) demonstrates soft tissue edema (asterisk) above the mastoid process (curved arrow), a 1.19×0.61-cm reactive upper posterior mastoid lymph node (arrowhead) with a marked hilar vascularity (arrow) and no ultrasound signs of suppuration. The oval shape of the node corresponds to reactive lymphadenitis. Depth of ultrasonography is 3.0 cm.
