Every once in a while it is advisable to test ourselves on our retained knowledge. We work hard and often our information, hard won by hours of study, fades and gets lost. Here is a quick simple review of some of our breast anatomy and of a few of the common pathologies that plague the breast.
Good luck and I hope this turns out to be a good review for everyone. Please choose the BEST answer.QUIZ
A lesion located in the upper
outer quadrant of the R breast would be described as being at:5 o’clock
2 o’clock
10 o’clock
7 o’clock
8 o’clock
Montgomery’s tubercles are usually found:
On the nipple
On the lateral border of the
breastIn the TLDU
On the skin of the areola
In the Ampulla
An inverted nipple
Always indicates breast cancer
Sometimes indicates breast
cancerNever indicates breast cancer
Usually indicates breast cancer
Is a rare occurrence
Compression of the breast is most effective when applied to the
Medial/Lateral aspect
Inferior/Superior aspect
Medial/Superior aspect
Inferior/Lateral aspect
Lateral/Superior aspect
The normal breast may have
5-10 lobes
15-20 lobes
25-30 lobes
30-40 lobes
More than 40 lobes
The structure that gives the breast its support and shape is called the
Montgomery ligament
Cooper’s ligament
Fibroglandular tissue
Adipose tissue
Pectoral Fascia
The breast extends vertically from the
1st to 9th rib
2nd to 9th rib
2nd to 6th rib
3rd to 10th rib
Manubrium to Xiphoid process
The thickest portion of the breast is the
Areola
Nipple
Tail-of-Spence
IMF
Deep Fascia
Cooper’s Ligaments attach anteriorly to
Deep Fascia
Fascia of the skin
Posterior breast surface
Parenchyma
Fatty tissue
The fatty tissue of the breast is generally………… and appears on the mammogram as areas of………….OD
Radiolucent/lower
Radiopaque/higher
Radiolucent/higher
Radiopaque/lower
Fatty tissue does not image well in film/screen mammography
Typically, a patient with dense fibro-glandular tissue throughout the entire breast is age
Under 20 yrs.
Over 50 yrs.
Over 70 yrs.
Under 40 yrs.
Between 50 and 69 yrs.
Typically, glandular tissue is mainly in the…………..of the breast tissue
Medial/LI quadrant
Central/UO quadrant
Medial/LO quadrant
Central/UI quadrant
Central/LI quadrant
Lymph drainage from the medial ½ of the breast tends to be through the
Sternal nodes
Transpectoral nodes
Axillary nodes
Apical nodes
Cutaneous plexus
Immediately behind the nipple the main duct widens to form the
Lobule
Ampulla
TLDU
Segmental duct
Branching duct
The anatomy of the breast which acts as the milk-producing element is the
Ampulla
Segmental duct
Lobule
Lactiferous sinus
Montgomery’s tubercles
In the image below we are visualizing
- Calcified vessels
- DCIS
- Egg shell calcification
- Casting calcifications
- Calcified fibroadenoma
The TLDU consists of
Mammary ducts/extralobular terminal duct
Intralobular terminal duct/segmental ducts
Extralobular terminal duct/lactiferous duct
Acini/lactiferous duct
Extralobular terminal duct/Intralobular terminal duct
A patient begins HRT 6 months before her current mammogram. The image
is likely to beUnchanged
Higher in glandular tissue
Lower in glandular tissue
Higher in adipose tissue
Easier to interpret
If the mammogram shows the patient’s breast tissue is less than 25% mammographically dense, this patient is most likely
Taking estrogen
Older than 60yrs.
Younger than 20yrs.
Older than 35yrs.
A low cancer risk
A lactating patient is scheduled for a routine screening mammogram
The test should be postponed because of breast sensitivity
Radiation does not affect lactation the test should be done
The patient should come fully involuted and the test should be done
The test should be rescheduled because of increased cancer risk
The test should be rescheduled because of the greatly increased density of involuted
breasts
A patient that is not on HRT has gone through the onset of menopause 1 year prior to her current mammogram. The current mammogram is most likely to be
Unchanged
Higher in glandular tissue
Lower in glandular tissue
Lower in adipose tissue
Easier to interpret
Which of the following will affect the ratio of glandular tissue to the total breast tissue
Genetic predisposition
Body Fat : Body Weight
Weight gain and/or Weight loss
I
I & II
II & III
I, II & III
A lactating patient is scheduled for diagnostic mammogram to assess a symptom
The test should be postponed until the patient stops breast feeding
The patient should wean her child and have the test
The mammographer should perform spot views only
The test should be rescheduled due to highly dense breast tissue
The patient should breast feed immediately before the appointment and the test should be done
A nulliparous patient has
Never given birth to a child
Had 1 child
Never produced viable offspring
Had 1 full pregnancy
Had at least 1 miscarriage
An asymptomatic patient presents with an oval, lobulated, indistinct mass with no halo
If the lesion is lucent it likely benign
The lesion is suspicious of malignancy
All oval lesions are benign
The absence of a halo indicates cancer
All lobulated lesions are suspicious
The lesion in the following image suggests
DCIS
A malignant type tumor
A cystic type lesion
A benign type lesion
A smooth mobile lesion
The calcifications in the image bellow:
- Are typically benign
- Are egg shell type
- Are typical of fibroadenoma
- Are smooth
- Are typically malignant
The characteristics of a malignant stellate tumor include
Spicules bunched together
A central dense mass
Tumor and spicules similar in size (e.g. Larger tumor/longer spicules)
Long wispy spicules
I
I, II & IV
II & III
I, II, & III
II & IV
The calcifications in the image below have the typical appearance of
An oil cyst
Plasma cell mastitis
DCIS
Lipoma
Calcified artery
The calcifications in the imagebelow have the typical appearance of
- An oil cyst
- Plasma cell mastitis
- DCIS
- Lipoma
- Calcified artery
31. A mammogram shows a low density radiopaque lesion. It is lobulated and has a halo demonstrated along one border only. The next step should be
- Pneumocystography
- U/S
- Biopsy
- Nothing, the lesion is benign
- FNA
32. The lesion in the image below has the typical appearance of
- A Cyst
- LCIS
- An Oil Cyst
- Invasive Ductal Ca
- A Lymph node
