Epikrise:
Liver abscess in a 54 y male patient with immunosuppression (kidney transplantation) and bile duct stenosis. On presentation the patient was septic. Ultrasound shows a 3.5 cm anechoic lesion with some inner echogenic structures. After contrast injection the typical thin hypercontrasted margin can be seen in the arterial phase.

For better visualization due to didactic reasons the playback speed got reduced to 50-75%.
