title: CT of Atypical and Uncommon Presentations of Hepatocellular Carcinoma.
abstract: OBJECTIVE
  The purpose of this article is to familiarize radiologists with uncommon presentations of hepatocellular carcinoma (HCC) with an emphasis on the CT spectrum of atypical appearances.
  
  
  CONCLUSIONS
  HCC is the fifth most common neoplasm worldwide and the second most common cause of cancer-related death. In many cases, HCC can be confidently diagnosed with noninvasive imaging. However, there are numerous unusual appearances of HCC with which the radiologist must be familiar.
