Questions With Verified Answers
Simple cysts may regress after menopause, but may perisist in women taking _______.
HRT
Result from obstructed lactiferous ducts due to fibrosis or proliferative changes in the duct
epithelium. Or can result from hormonal dilatation.
Cysts
Mammographic appearance of a cyst. (4)
1. Round or oval
2. Smooth (circumscribed) margins
3. Radiopaque - Water Density
4. Halo Sign (lucent rim of fat)
Sonographic appearance of a cyst
Round or oval, anechoic, well circumscribed, *acoustic enhancement, may have edge shadowing,
occasionally lobulated, compressible, no internal doppler signal.
These three criteria are required to classify a cyst as "simple"
Three criteria required for a cyst to be classified as simple.

Artifacts within a cyst may be caused by... (9)
1. TGC
2. Overall gain
3. Focal position
4. Small size
5. Superficial location (use standoff)
6. Deep location
7. Side or grating lobe artifact
8. slice (section) thickness artifact
9. Volume averaging artifact
Types of non-simple cysts ((5)
1. Complicated cysts
2. Complex cysts
3. Clustered microcysts
4. Septated cysts
5. Calcified cysts
, Cyst containing homogeneous low level internal echoes with fluid-fluid or fluid-debris levels which
react to gracity. Malignancy is 0-1.4%.
Complicated cyst
Refer to chart on page 75 to list the types of complicated cysts and their contents.
Do it.
No Doppler flow will be detected within the debris of a __________ cyst.
Complicated
_________ can reveal the true nature of the complicated cyst.
Cytology (upon aspiration)
Cysts which contain a solid component.
Complex Cyst -- **managed differently than complicated cysts due to higher malignancy rate.
What is the malignancy rate for a complex cyst?
23%
Cyst with partial or total wall calcification.
Calcified cyst
Cyst that contains one or several internal septations.
Septated cyst
Commonly seen as fibrocystic changes on mammography and sonography. May be difficult to
distinguish from a hypoechoic mass.
Clustered microcysts
A milk filled cyst caused by the obstruction of a lactiferous duct. Usually ass'd with childbirth, affecting
both breast feeding and non breast feeding mothers.
Galactocele
A galactocele is typically located where?
The subareolar region
A galactocele may be what echogenicity?
Hypoechoic to isoechoic -- but will be homogeneous, wil enhance, and will have no Doppler signal.
What else may be present with a galactocele?
Dilated ducts, mastitis, abscess
Results from an obstructed sebaceous gland associated with the skin of the breast.
Sebaceous cyst
