11) Women, Men, and Children Flashcards
Women’s imaging
- Mammography and the female breast
- Gynecological conditions
- Obstetrical conditions
Breast cancer
- Leading cause of non-preventable cancer death in women
- 180,000 cases per year; 46,000 deaths
Risk of breast cancer increases with
- Age, especially after 40
Mammography can detect
- Presence of early breast cancer at the non-palpable stage
Mammography cannot rule out breast cancer in a patient with
- Palpable mass or other abnormality on clinical examination
- Basically it can rule in cancer, but it cannot rule it out
Screening mammography
- Performed on asymptomatic women to detect unsuspecting cancer at an early age
Diagnostic mammography
- Problem-solving mammography
- Performed to evaluate abnormal clinical findings
There is general agreement that all women over the age of 50 should have
- Annual screening mammograms (some sources say over 40)
A mammogram consists of two views of each breast
- Mediolateral oblique (MLO)
- Craniocaudad (CC) view
The augmented breast poses problems with mammography
- Implant can obscure up to 85% of the tissue
- MRI can be done in these patients
- Ultrasound can be performed to evaluate implant leakage
Risk factors for breast cancer
- Maternal relative with breast cancer
- Longer reproductive span
- Obesity
- Nulliparity
- Later age at pregnancy
- Atypical hyperplasia
- Previous breast or uterine cancer
Breast Imaging Reporting and Data System (BIRADS) defines five type of margins
- Circumscribed
- Obscured
- Micro-lobulated
- Ill-defined
- Spiculated
Circumscribed margins
- Well defined
- Sharply demarcated with an abrupt transition between the lesion and the surrounding tissue
Microlobulated margins
- Small undulating circles along the edge of the mass.
Obscured margins
- Hidden by superimposed or adjacent normal tissue
Ill-defined margins
- Poorly defined and scattered
Spiculated margins
- Marked by radiating thin lines
BIRADS assessment categories
- Category 0-5
Category 0
- Need additional imaging evaluation
Category 1
- Negative
Category 2
- Benign finding
Category 3
- Probably benign finding
- Short interval follow up suggested
Category 4
- Suspicious abnormality
- Biopsy should be considered
Category 5
- Highly suggestive of malignancy
- Appropriate action should be taken
A spiculated, dense mass especially when not palpated is almost always
- Carcinoma
Skin calcifications
- Typical lucent center
- Polygonal shape
- Not in the breast parenchyma, but may project as such on a mammogram
Vascular calficifications
- Seen as parallel tracks or linear tubular calcifications that run along a blood vessel
Coarse or popcorn-like calcifications
- Typically found in involuting fibroadenomas
- Fibroadenomas usually regress with menopause and microcalcifications will develop into coarse macrocacifications
Rod-shaped calcifications
- Typical of secretory disease but not of breast cancer
- Usually >1mm, occasionally branching, and may have lucent centers
- Form in debris that collects in the duct lumen or cause an inflammatory reaction around a duct
Round calcifications/smooth round calcifications
- Associated with a benign process
- May vary in size in a cluster
- When <1mm they are often found in the acini of lobules
- When <0.5mm the term punctate is used
