Q

cirrhosis

A

a chronic, degenerative disease of the liver where the hepatic lobes are covered with fibrous tissue.
the parenchyma degenerates, and the lobules are infiltrated with fat.
(80% of cancer is from this)

Q

hepatic abscess

Study These Flashcards
A

a pus-filled mass in the liver

24
Q

pyogenic abscess

Study These Flashcards
A

a pus-filled pocket of fluid that can form from infection in the blood, abdominal infection, or an abdominal injury that has become infected.

25
hepatic candidiasis
in infection within the liver where a certain yeast fungus called candida is present.
26
amebic abscess
caused by the protozoan parasite, entamoeba histolytica. parasites enter the liver via the portal vein.
27
echinococcal cyst
parasitic tapeworms that are common in sheep-herding areas in the world; most commonly found in people under the age of 20.
28
schistosomiasis
the most common parasitic infection due to bad water
29
Hematoma
swelling or clotting within the liver tissues
30
cavernous hemangioma
benign tumor of the liver
31
liver cell adenoma
benign nodule in the liver that contains hepatocytes; usually solitary. - 90% are found in women on long-term birth control - has a halo
32
focal nodular hyperplasia
second most common benign hepatic mass; contains all cellular elements of normal liver, but lack normal structure.
33
Lipoma
rare fatty tumor in the liver (AKA: angiomyolipoma)
34
Hepatocellular carcinoma (HCC)
most common primary malignant liver tumor
35
metastasis
where cancer spreads to other parts of the body; this is where it effects the tissue, but comes from another primary site
36
Hemangiosarcoma
a rare, but aggressive malignant tumor in the liver - exposure to chemicals
37
liver transplantation
the surgical removal of a liver with the intent of replacing it with another, more healthy liver.
38
what are some complications of a liver transplant?
- rejection (fluid) - thrombosis - biliary stricture - infection - neoplasia
39
what are some reasons someone might need a liver transplant?
- hepatitis C - cirrhosis - biliary atresia in infants
40
mild (grade 1) of fatty infiltration
minimal diffuse increase in hepatic echogenicity with normal visualization of diaphragm and intrahepatic vascular borders.
41
moderate (grade 2) of fatty infiltration
increased echogenicity with slightly impaired visualization of diaphragm and intrahepatic vascular borders.
42
severe (grade 3) of fatty infiltration
significant increase in echogenicity of the liver parenchyma, decreased penetration of the posterior segment of the right lobe of the liver, and decreased to poor visualization of the diaphragm and hepatic vessels.
43
what are 4 causes of fatty infiltration of the liver?
1) obesity 2) excessive alcohol intake 3) diabetes 4) pregnancy
44
polycystic liver disease
a rare genetic disorder characterized by mutations in genes encoding for proteins involved in the transport of fluid and growth in the epithelial cells of the liver.
45
autosomal dominant; afffects mainly females over 50
polycystic liver disease
46
polycystic liver disease on ultrasound
multiple cysts throughout the liver.
47
criteria for a cyst
- well-defined edges - filled with fluid - posterior enhancement - thin, echogenic walls
48
what is usually the cause of portal hypertension?
cirrhosis
49
what is the most common type of glycogen storage disease?
type 1 or Von Gierke disease - this is where abnormally large amouts of glycogen are deposited in the liver and kidneys.
50
present with hepatomegaly, and increased echogenicity, 40% with adenomas
glycogen storage disease
51
ultrasound indicator of diffuse liver disease
gallbladder walls are super thick; looks like a donut
52
lab values for cirrhosis patients
elevated AST, ALT, and Bilirubin
53
symptoms of cirrhosis
- N/V - weight loss - anorexia - jaundice - dark urine - clay-colored stool -varicosities
54
causes of cirrhosis
- alcohol abuse, infection, or viral hepatitis
55
what are the most common metastatic cancers?
colon, breast, and lung
