What are the CP and SF of hepatitis?
Fever, chills, marked increase AST, ALT, bilirubin - normal-appearing liver, increased portal wall echogenicity
Most common and second most common benign liver lesion?
- hemangioma 2. FNH
Sonographic features of FNH
hyperechoic/isoechoic, hypoechoic central stellate scar, peripheral and central blood flow, well defined margins
Is focal fatty sparing hypo or hyperechoic?
HYPOechoic
is focal infilatration hypo or hyperechoic?
HYPERechoic
Increases the risk of cirrhosis, portal HTN, and HCC
Hepatitis
Fecal oral route hepatitis
Hep A
contact with contaminated body fluid hepatitis
hep B
What is periportal cuffing and when is it found?
increased echogenicity of portal triads with hepatitis - “starry sky”
dark urine, elevated LFT, jaundice, fever, fatigue, chills are CP of what?
hepatitis
tapeworm from dog feces
hydatid/echinococcal
tumor marker for HCC and hepatoblastoma is?
AFP
most common mets to liver
colon, panc, breast, lung, GB, stomach
target or bulls-eye lesion
hepatic mets
liver pathology assossicated with Beckwith-Wiedemann syndrome
Hepatoblastoma
budd chiari leads to a reduction in the size of the
hepatic veins
m/c symptomatic pediatric vascular liver tumor
hemangioendothelioma
Fibrolamellar HCC
- better prognosis than HCC
- SF include calcs unlike HCC
- AFP values are NORMAL
- NO increased risk factors
recanalized paraumbilical vein is seen with which pathology?
Portal hypertension
Flow directions in the R/L portal veins with a TIPS
hepatoFugal
A recanalized paraumbilical vein will have flow in which direction?
hepatoFugal
a decrease in serum albumin suggests?
HCC
flow in the MPV is described as
phasic
caudate lobe enlargement is seen with which pathology?
cirrhosis
dark urine is found with which liver disease
hepatitis
True or false: Cavernous hemangiomas are hormone dependant
TRUE
True or false: Hemangioma, adenoma’s and FNH are all hormone dependant?
TRUE
True or false: hemangiomas cause a speed error artifact
FALSE
True false: Live Lipomas can cause a speed error artifact?
TRUE
true or false: calcifications are a common SF of HCC
FALSE
true or false: fibrolamellar carcinoma is encapsulated
TRUE
characteristics of hepatoblastoma
- increase AFP
- SF: calcs, ill defined, mixed echogenicities
- CP: failure to thrice, fever, anemia, jaundice
This is a common FUNGAL opportunistic infection in AIDs patients, CP’s are difficulty breathing, ever, dry cough. SF are: diffuse, tiny non-shadowing echo foci
Pneumocystis carinii
Pyogenic abscesses are fungal, parasitic or bacterial?
bacterial
Candidiasis and Pneumocystis carinii are fungal, parasitic or bacterial?
fungal
Amebiasis, hydatid, schistosomiasis are fungal, parasitic or bacterial?
parasitic
a positive indirect hemagglunation test is present in a patient with which pathology?
Amebiasis parasite
a child presents with convulsions, hypoglycemia, nose bleeds, lethargy what is the diagnosis based on these CP’s?
Glycogen storage disease - has SF of cirrhosis
ascites, GI bleeding, splenomegaly, varices are CP of what pathology?
Portal hypertension
ALP might be elevated with which pathologies?
cirrhosis, hepatitis, gallstones, mets
ALT may be elevated with which pathologies?
hepatitis, obstructive jaundice
AST may be elevated with which patholgies?
cirrhosis, fatty liver, hepatitis, mets
describe facts about Liver adenomas
rare, increased with birth control, can become malignant, non-specific sono appearance
