Repeat CT abdomen showed multiple persistent low density hepatic lesions, the largest measuring 4.9 x 3.3 x 5.9 cm as well as extension of the portal venous thrombosis (Fig. 1A-B).
On examination of the cell block section, the liver abscess drainage consists of acellular debris and acute inflammatory cells (hematoxylin and eosin stain, original magnification x400).
