The white liver sign refers to a spontaneously hyperdense appearance of the liver on non-injected abdominal CT [1]. The accumulation of substances in the liver, such as iron in hemochromatosis, copper in Wilson’s disease, or drugs such as amiodarone, can result in diffusely increased attenuation of the liver parenchyma [2] (Fig. 1), as compared with the spleen and surrounding tissue. In the presence of a white liver sign, the attenuation value of the liver is about 110 HU, while the normal mean liver attenuation is approximately 55 HU (Fig. 2) [2‐5].
