Section 1 – Quiz | |  |
A 60-year-old male had one painful, erythematous mass of the inferior abdominal wall for 3 months. He received a hernia repair surgery 1 year ago. Wound infection developed after the surgery, and an abscess was formed nearby. He received debridement, but there was only partial improvement. Under the impression of a residual abscess, ultrasound was arranged, revealin a hypoechoic lesion [Figure 1]a with peripheral hyperemia [Figure 1]b. A subcutaneous abscess with active inflammation was diagnosed. Furthermore, a hyperechoic structure was found in its center with diverging acoustic shadows [Figure 1c]. What is your impression about these findings in [Figure 1]c? | Figure 1: (a) The image was obtained by placing the transducer in the sagittal plane over the mass (arrowheads). (b) The image was obtained in the power Doppler mode showing hyperemia surrounding the mass. (c) The diverging artifacts (white arrows) behind the hyperechoic structure (black arrowhead) were observed
