Normal liver:

In this sonographic image, note the normal echogenicity of the liver which is almost isoechoic with the parenchyma of the right kidney.

Diffuse fatty change of liver:

In this ultrasound image of the liver there is diffuse increase of liver echogenicity. The liver appears markedly hyperechoic as compared to renal cortex.

Diffuse fatty liver with focal fatty sparing:

In these 3 ultrasound images there is diffuse fatty change of liver with focal fatty sparing in the periportal region, just anterior to the porta hepatis. This is a typical site of focal fatty sparing. This is seen as a small hypoechoic region. Images taken with a Pie Scanner 100 Falco, by Dr. Joe Antony.

Focal fatty change of liver:

The above ultrasound image (left) shows a hyperechoic lesion of 4 x 3 cms. in the periphery of right lobe of liver. Color doppler scan shows absence of mass effect (vessels are not displaced by the lesion). This suggests focal fatty change of liver. Such lesions may change rapidly over time. Images taken using a Medison SA 8000 color doppler machine, courtesy of Dr. Arun Mahajan, Delhi, India.

3) Focal fatty change of the liver, a hitherto poorly recognized entity. (interesting insight into the causes of focal fatty change of liver).

Cirrhosis of liver with portal vein thrombosis:

This patient presented with distension of abdomen. Sonography of the abdomen showed: a) large ascites (fluid collection inside the peritoneal cavity). The anechoic fluid is seen surrounding the liver and the kidneys. b) There is also a moderate collection of fluid in the pleural cavity (pleural effusion). This is seen as fluid just above the diaphragm. c) Nodularity of the liver is present. This is seen as irregular surface of the right and left lobe, well outlined by ascitic fluid. d) There is also coarse echotexture of the liver with increased echogenicity. e) There is also relative increase in size of the left lobe of liver- the so-called volume redistribution in the size of liver. f) Lastly, Color Doppler imaging shows a thrombus in upper portal vein which appears moderately dilated (14.5 mm.). There is also evidence of splenomegaly. These ultrasound images are diagnostic of cirrhosis with portal vein thrombosis. Images courtesy of Gunjan Puri, MD, India.
