In this series of papers on comments and illustrations of the World Federation for Medicine and Biology (WFUMB) guidelines on contrast enhanced ultrasound (CEUS) the topics of bacterial infections are discussed. Improved detection and characterization of common focal liver lesions (FLL) are the main topics of these guidelines but detailed and illustrating information is missing. The focus in this paper on infectious (bacterial) focal liver lesions is on their appearance on B-mode and Doppler ultrasound and CEUS features. Knowledge of these data should help to raise awareness of these rarer findings, to think of these clinical pictures in the corresponding clinical situation, to interpret the ultrasound images correctly and thus to initiate the appropriate diagnostic and therapeutic steps in time.

In this second part of the topic the hepatic pseudoaneurysm, hepatic infarction, and pylephlebitis are discussed as acute and potentially life-threatening hepatic vascular diseases. The focus is on their appearance on B-mode ultrasonography, duplex ultrasonography, and contrast-enhanced ultrasonography. Zahn’s pseudo infarction is an important differential diagnosis to wedge-shaped hepatic infarction in this context. Knowledge of the data should help raise awareness of these rare findings, to come up with relevant differential diagnoses in the corresponding clinical situation, to interpret the ultrasound images correctly and thus to initiate the appropriate diagnostic and therapeutic steps in time.
