Figure 12: A 25-year-old male patient presented with fever and right upper quadrant pain. Ultrasound showing hypoechoic lesion in the liver (white arrow, a). Contrast-enhanced ultrasound of the same lesion showing no enhancement of the lesion at 25 s (white arrow, b) after contrast injection (arterial phase). Contrast-enhanced ultrasound of the same lesion showing mild peripheral enhancement at 85 and 160 s (white arrow, c and d) (portovenous and delayed phases) suggesting abscess. Later, the diagnosis is confirmed by aspiration and culture showing growth of Klebsiella
