• Fig GI 70-1 Fatty infiltration. Sagittal scan demonstrates a diffuse increase in echogenicity of the hepatic parenchyma with marked attenuation of the sound beam.95

Fig GI 70-2 Focal fatty infiltration. Longitudinal scan shows a well-defined, densely echogenic focus within the liver.108

• Fig GI 70-3 Fibrosis. Diffuse increased echogenicity of the liver secondary to chronic hepatitis.

• Fig GI 70-4 Cirrhosis. Transverse scan shows a small, contracted liver (L) with increased echogenicity surrounded by ascitic fluid (arrow). (P, portal vein.)95

Fig GI 70-5 Cirrhosis with portal hypertension. Transverse scan shows multiple venous collaterals (arrowheads).95

• Fig GI 70-6 Kaposi sarcoma. Sagittal sonogram through the right upper quadrant shows abnormal heterogeneous increase in echogenicity of the liver, with multiple hyperechoic lesions throughout the hepatic parenchyma.109
