80
Q

fatty infiltration implies increased ___ accumulation in the hepatocytes and results from significant injury to the liver or a systemic disorder leading to impaired or excessive metabolism of fat.

A

81
Q

describe the sonographic findings for fatty infiltration of the liver

A

Moderate to severe fatty infiltration shows increased echogenicity on ultrasound. Enlargement of the lobe affected by fatty infiltration is evident. The portal vein structures may be difficult to visualize because of increased attenuation of the ultrasound. Increased attenuation also causes a decrease in penetration of the sound beam, which may be a clue for the sonographer to think of fatty liver disease. Fatty infiltration is not always uniform and may demonstrate areas of focal sparing. The most common areas of focal sparing are located anterior to the gallbladder and portal vein and the posterior portion of the left lobe.

Q

List the criteria that the sonographer should use to determine whether the mass is extrahepatic or intrahepatic

A

Intrahepatic masses may cause: displacement of the hepatic vascular radicles, external bulging of the liver capsule, or posterior shift of the IVC. Extrahepatic masses may show internal invagination or discontinuity of the liver capsule, formation of a triangular fat wedge, anteromedial shift of the IVC, or anterior displacement of the right kidney
