1

Solid liver lesions in older patients are more likely to be what?

Malignant with metastases more common than primary liver cancer in the absence of liver disease

2

WHat are solid liver lesions in patients with chronic liver disease more likely to represent?

Primary Liver Cancer rather than metastases or benign tumour

3

What is the most common solid liver tumour in non cirrhotic patients

Hemangioma (benign)

4

Name 4 benign liver tumours

Hemangioma
Focal nodular hyperplasia
Adenoma
Liver cysts

5

Name the 2 main types of malignant tumours

Primary liver cancers
Metastases

6

What are the 2 types of Primary liver cancers

Hepatocellular carcinoma
Cholangiocarcinoma

7

What is the commonest liver tumour

Hemangioma

8

Describe a hemangioma

A vascular tumour
Usually single and small
Well demarcated capsule
Usually asymptomatic

9

How do we diagnose a Hemangioma

Ultrasound is key
CT
MRI

10

What is the treatment for hemangioma

No treatment

11

Describe a focal nodular hyperplasia

enign nodule formation of normal liver tissue
congenital anomaly

12

What is the classic appearance of a focal nodular hyperplasia

A central scar through the middle of the mass

13

Who is more likely to have a focal nodular hyperplasia

Young and middle aged women

14

What type of response is a focal nodular hyperplasia?

A hyperplastic response to abnormal arterial flow

15

How can we diagnose a focal nodular hyperplasia

Ultrasound
CT
MRI
Fine needle aspiration

16

What is the treatment for Focal nodular hyperplasia

No treatment
No change is required for pregnancy or hormones

17

What is a hepatic adenoma

Benign neoplasm composed of normal hepatocytes with no portal tract, central veins or bile ducts

18

Who is more likely to get hepatic adenomas?

Women

19

What are hepatic adenomas associated with

The contraceptive hormones - mostly oestrogen

20

What are the symptoms of hepatic adenoma

Usually asymptomatic but may have RUQ pain

21

How might hepatic adenomas present

Rupture, haemorrhage or malignant transformation

22

Where are hepatic adenomas most commonly found

In the right lobe in young women

23

How can regression of hepatic adenomas occur

If the oral contraceptive is discontinued

24

How can we diagnose hepatic adenoma

US
CT
MRI
FNA

25

What is the treatment for hepatic adenomas

Stop the hormones and observe every 6 months for 2 years
If there is no regression then surgical incision may be appropriate

26

What liver structures do adenomas contain

Purely hepatocyte tumours

27

What liver structures do focal nodular hyperplasias contain

All of the liver ultrastructure - RES and bile ductules

28

What type of benign tumour imay bleed

Adenoma

29

What type of benign tumour has the risk of developing into a malignant tumour

Adenoma

30

How can you describe both adenomas and focal nodular hyperplasia

Hypervascular
