A Case Report of Two Patients with Delayed Complications after Hepatic Injury Detected by the High-density Imaging of Multidetector Row Computed Tomography

Abstract

This report presents useful images of high-density imaging (collimation, 3mm) by multidetector row computed tomography (MDCT) in two patients with blunt hepatic injury, resulting from the use of the multidynamic phase scan method, or dripinfusion cholangiography (DIC). The data were visualized on a workstation (ZioM900, Ziosoft Inc., Tokyo). A liver pseudoaneurysm was identified with MDCT in a 21-year-old male on the 14th day following an injury in a by motorbike accident. The pseudoaneurysm gradually faded out in 3 weeks. In a 24-year-old male, 7 days after a motor accident injury, a huge liver pseudoaneurysm was identified with MDCT. The pseudoaneurysm involved the fistula to the hepatic vein (HV) and HV-portal shunt. In addition, bile leakage from the disinsertion of the left hepatic duct was identified on the 14th day with DIC-MDCT.
