Abstract

|
We present two cases of focal fat deposition developed at the posterior area of the segment IV in the liver, following gastrectomy in patients with gastric cancer. There was no focal lesion in this area of the liver at preoperative computed tomography (CT) in both cases, and the aberrant right gastric vein (ARGV) was found on the retrospective review of this CT. After gastrectomy, a focal, low-attenuating lesion was developed in this area on a follow-up CT in both cases, which was confirmed as a focal fat deposition, by other imaging studies. In addition to its typical imaging findings, confirmation of the presence of the ARGV also supported this lesion to be a focal fat deposition. Furthermore, understanding of our cases may be of help to prevent us from unnecessary invasive procedures, such as liver biopsy.
