The authors describe a particular ultrasound finding which can sometimes be observed in the echographic picture of diffused hepatic steatosis and which was seen by these Authors in 117 out of 312 patients affected by steatosis. This finding consists of the presence of one or more hypoechoic focal areas situated at the IV-V and/or II-III segment level surrounded by widespread increase in echogenicity of remaining parenchyma, which is typical of "bright liver". These areas, which can easily be mistaken for neoplastic formations, were instead seen to be limited areas of normal liver parenchyma free of fatty infiltration. In those patients presenting valid reasons for suspecting the presence of primary or secondary neoplastic formations, the Authors believe that echographic examination of these areas should always be accompanied by more invasive methods in order to confirm or exclude the possible presence of neoplastic formations with certainty. On the contrary, in those patients where no such diagnosis is suspected, it should prove sufficient to monitor these areas by means of ultrasounds.
