FCC

Fibrocystic Change

2

What is the most common benign diffuse breast condition?

Fibrocystic Change

3

What are the symptoms of FCC? (3)

1. Breast tenderness
2. Fullness
3. Nodularity

4

What age group does FCC typically occur in?

35-50

5

How does FCC appear on US? (2)

1. Multiple cysts of varying sizes in both breasts
2. Fibroglandular tissue

6

Fibroglandular tissue

Basket weave appearance with ductal prominence

7

What is related to FCC?

Simple cysts

8

What are simple cysts a result from?

Dilatation and effacement of the terminal duct lobular unit

9

What is the most common cause of breast lumps for 35-50 year old women?

Simple cysts
- single or multiple

10

How can a cysts be classified as simple?

It must satisfy all the sonographic criteria set forth
- anechoic
- well circumscribed
- thin echogenic capsule
- increased through-transmission
- thin edge shadows

11

What happens once a mass meets all the criteria for a simple cyst?

It is classified as BI-RADS 2

12

What is considered to be a complicated cyst?

A cyst that meets all the criteria of a simple cyst except that it contains low-level internal echoes or fluid–fluid or fluid–debris levels that can shift with changes in the patient's position

13

What are causes of internal echoes? (6)

1. Cell debris
2. Protein
3. Cholesterol
4. Blood
5. WBCs
6. Epithelial cells

14

Complex cysts

A cyst with thick walls or some discrete solid component
- eg) septa greater than 0.5 mm thick or mural nodules

15

What is the differential diagnosis for a cyst with a mural nodule? (4)

1. intracystic papilloma
2. Atypical ductal hyperplasia
3. Ductal carcinoma in situ
4. Papillary carcinoma

16

What is the differential diagnosis for a complex cyst? (5)

1. Hematoma
2. Fat necrosis
3. Abscess
4. Galactocele
5. Necrotic neoplasm

17

What kind of cyst is it if it is mobile?

Complicated cyst

18

What kind of cyst is it if it is not mobile?

Fixed cyst

19

What is the most common benign mass to develop in a lactating patient?

Galactocele

20

Where does galactocele form from?

The accumulation of milk distal to an obstruction in the terminal ductal unit

21

How does galactocele appear on the US? (2)

1. Round or oval circumscribed mass
2. Uni or multi lobular

22

What determines the mammographic and sonographic appearances for galactocele?

The age of the milk products contained in the galactocele

23

What happens as the age of the milk products contained in the galactocele ages?

The cyst increases in complexity

24

What do complex cysts develop? (2)

1. Echogenic foci
- due to separation of the fat components
2. Fat–fluid levels with the echogenic component layering in the nondependent portion

25

What happens when the milk curdles in a galactocele?

Leads to the development of a solid component within the cyst
- appearing as a solid echogenic mass

26

What can galactocele become?

Lipid (oil) cysts

27

Sebaceous cysts

Small, benign skin appendage masses that result from obstructed sebaceous glands

28

Where are sebaceous cysts located?

Inferior or medial margins of breast or near axilla

29

What is the shape and margins of a sebaceous cysts? (2)

1. Shape = round or oval
2. Margin = smooth with thin wall circumscribed margins

30

What is the echogenicity of sebaceous cysts? (3)

1. Anechoic
2. Internal echoes
3. Fluid fat levels
