Abstract
A 64-year-old man was referred to our hospital with high fever and right upper abdominal pain. Dynamic computed tomography (CT) scan revealed a 60×40-mm abscess in the right lobe of the liver. B mode and color doppler ultrasonography (US) imaging of the abdomen could not depict the abscess as clearly as the CT. An 81-mm hypervascular lesion was observed in segment 5/6 during the early vascular image of contrast-enhanced US performed using Sonazoid®. A 50.2×39.7-mm defect, which was considered to represent necrosis and cavity of the abscess, was clearly depicted during the Kupffer image of imaging. Percutaneous transhepatic drainage of the abscess was performed safely under contrast-enhanced US guidance (during the Kupffer image of imaging). The size of the abscess and the clinical healing course were tracked using the Kupffer-image imaging data. This case suggests that contrast-enhanced US with Sonazoid® is an excellent modality for treatment and follow-up of a liver abscess.
