Fatty Infiltration Flashcards
what is fatty infiltration
Acquired, reversible condition, results in an intrascellular accumulation of triglyercides within hepatocytes
what condition is the patient in in fatty infiltration
Patient is usually asymptomatic
what are symptoms of fatty infiltration
Jaundice
· Nausea
· Vomiting
· Abdominal tenderness or pain
what blood tests are associated with fatty infiltration
· Normal to Increased hepatic enzymes,
· Increased Alkaline phos
·Increased direct bilirubin
what happens to the echogenicity of the liver in fatty infiltration
Echogenicity increases
Is there increased or decreased attenuation in fatty liver?
increased attenuation
what occurs to the appearance of borders in hepatic structures?
Impaired visualization of borders of portal/hepatic structures (secondary to increase attenuation)
Liver may _______in size
Increase (hepatomegaly)
what may the appearance of fatty liver be?
Patchy and inhomogenous
Is fatty infiltration always uniform?
No
what should be suspected in patients with masslike hypoechoic areas in typical areas of an echogenic liver
Focal sparing
where are the most common regions for focal sparing?
Anterior to the gallbladder
anterior to the portal vein
periportal region of medial segment of the left lobe of liver
what occurs in mild fatty infiltration
-Minimal diffuse increase in hepatic echogenicity with normal visualization of the diaphragm and intrahepatic borders
what occurs in moderate fatty infiltration
- increased echogenicity
- slightly impaired visualization of the diaphragm and intrahepatic vascular borders
what occurs in severe fatty infiltration
- marked increase in echogenicity
- decreased penetration of the right lobe
- decreased to poor visualization of the diaphragm and hepatic vessels
