mammary layer, retromammary layer, subcutaneous layer

Coopers Ligament
Fat (JL PG 553)
Echogenic (JL p 552)
thin and consist of fat surrounded by connective tissue septa
the fatty tissue appears hypoechoic and the ducts, glands, and supporting ligaments appear echogenic
(MW pg. 550)
smooth walls, anechoic, posterior enhancement good through transmission
(MW breast slide #6)
Fibrocystic condition (EG pg 574)
(MW breast slide #11)
fibroadenoma
Smooth, rounded margins low level homogeneous internal echoes posterior enhancement typically hypoechoic but can be hyperechoic because of the fat within the breast (JL pg 5765)
Axillary (JL pg 554)
Invasive Ductal Carcinoma (JL pg 578)
attenuation of sound
irregular borders
inhomogenous low level internal echo patterns with calcification
retraction of the tissue secondary to tumor infiltration
provides early detection of breast carcinoma
Mid portion of rt medial and Lt lateral breast is annotated 3:00
Palpable lump
tail of spence
40
anterior perforating branches of the internal mammary gland (JL pg 553) (internal mammary supplies have the blood supply to the breast)
gynecomastia (MW pg 556 and google)
Irregular margins and taller than wide
large core needle biopsy of calcification
