Do simple liver cysts have malignant potential? Do they often cause problems such as bleeding or pain? Do simple cysts affect LFTs? US/CT/MRI? |
polycystic kidney or liver dz
No. No. No. anechoic, homogenously hypodense, T1-dark, T2-light, no contrast enhancement; no septae |
|
|
If a liver mass found on imagining has septae, is it likely to be a simple liver cyst?
|
No.
|
|
|
What is a hepatic hemangioma?
How do they typically show up on CT? U/S? Technetium-labeled RBC scan? Gold dx standard? Often needed? Is size of the Hemangioma an indication for surgical resection? |
Benign blood vessel neoplasm
centripital enhancement Nonspecifically hyperechoic "hot" MRI w/ contrast, shows filling from the outside in; no. No; unless there are Sx, leave it alone. |
|
|
What is Kasabach-Merritt syndrome?
|
Giant cavernous hemangioma + consumptive coagulopathy
|
|
|
Hepatocytes and Kupffer cells radially oriented, emanating from a central scar... this describes which dz?
Dx? - ever need to biopsy? Gender predominance? Associated with oral contraceptives? |
Focal Nodular Hyperplasia (FNH)
see the central scar - TC-sulfur colloid --> "hot" - CT/MRI - need for biopsy is rare, but you have to do it if you can't see the scar in any other way. women No |
|
|
Which liver tumor (benign) is associated with oral contraceptive use, and glycogen storage dz?
- Typically seen where in the lv? - risk of rupture / malig degener? - what is seen on US? - regress w/ discontinuation of estrogen? - require removal? - what is seen on hepatic angiography? - T2 MRI w/gadolinium? - does biopsy carry risks? |
Hepatic Adenoma
- single, right lobe - yes - hyperechoic - yes - yes, especially if pt plans on getting pregnant - radiating vessels - hyperintense - yes, can cause hemorrhage. |
|
|
Which liver malignancy occurs 70-90% of the time in the presence of HBV, HCV, cirrhosis?
- screening in high risk pts? - dx for larger lesions? - smaller lesions (1-2cm)? |
HCC (hepatocellular carcinoma)
- Alpha-fetoprotein lvls (AFP) + Ultrasound - CT "triple phase"; looking for rapid arterial enhancement with rapid washout - liver biopsy |
|
|
Are the following risk factors for HCC?
Cirrhosis HBV HCV HHC ALD NAFLD |
Yes, all are risk enhancers.
|
|
|
If a pt with stable cirrhosis begins to quickly decompensate, what might you worry about?
Other potential indicators of this dz? |
HCC.
abdominal pain, ascites, jaundice, weight loss |
|
|
What are negative prog factors of HCC?
Can HCC pts still qualify for a liver txplt? What does dz management depend on? |
Severity of liver disease
Tumor size Multifocality Pathologic grade Vascular invasion Metastases Comorbid illnesses Yes, if they're healthy enough and the cancer is small enough. Staging and prog. features. |
