In this case severe staetosis of the liver is seen. The density of the liver is -9 HU in the selected region. The liver parenchyme appears hypodens compared to the normal intrahepatic vessels.
Steatosis of the liver is caused by abnomal accumulation of trigliceride within the hepatocystes, it can have a variety of different etiologies. The most frequent underlynig causes are alcohol abuse and obesity. It is also known that along with chemotherapy, many drugs can induce fatty degeneration of the liver. On ultrasonography the ehogenicity of the liver increases with fat deposition, hence the echogenicity can be compared to that of the kidneys, and spleen. On CT a threshold attenuation of 40 HU is generally used, below which the liver can be considered steatotic.
