Breast ( Images ) Flashcards
Layers of breast tissue ( superficial to deepest layer)
Subcutaneous layer
Mammary layer
Retromammary layer
Pectoralis muscles
The hypochoic pectoralis muscle is seen between the retromammary layer and the ribs.
Mastitis.
may appear as ill-defined areas of echogenicity with diffuse edema and hypochoic fluid within the subcutaneous tissue that outlines the fat lobules.
Breast abscess. This 6.8 cm complex mass was diagnosed as a breast abscess and was noted in a patient with coexisting mastitis.
Lipoma
appearing as an oval hyperechoic mass is noted just under the skin.
The hypochoic pectoralis muscle is seen between the retromammary layer and the ribs.
Subcutaneous fat is hypochoic, whereas Cooper’s ligaments appear echogenic within the subcutaneous layer
Metastatic spread of breast cancer to the opposite breast.
B, Image of one of the masses shows a solid mass with an irregular, poorly defined margin and heterogeneous echogenicity.
These lesions were all metastatic lesions from the opposite breast, likely from an alternative route of lymphatic spread across the midline.
Ultrasound image of a growing palpable mass in a teenage female.
This was one of several similar masses.
Fibroadenomas are frequently multiple and often run in families.
Note the hypochoic, homogeneous echogenicity of the mass, and the low-level posterior acoustic enhancement and edge refraction.
Biopsy needle can be seen.
Seroma.
This (noninfected fluid collection) has been repeatedly aspirated in this patient with previous silicone implants that ruptured.
Note the thick septations
Ruptured silicone breast implants.
A, Mammogram showing retroglandular implant with extracapsular silicone
B, Ultrasound image of the same case showing typical
“snowstorm” appearance of free extracapsular silicone
C, Ultrasound image of normal intact silicone implant. Note the anechoic appearance of the silicone and the double echogenic margin of the implant perpendicular to the incident sound waves
D and E, Two ultrasound images of the same silicone breast implant taken at separate times showing intracapsular rupture.
D, Note the echogenic fibrous capsule that is no longer a double line, but only a single line. Note the nonparallel echogenic interfaces within the silicone. These interfaces represent portions of the collapsed and ruptured envelope surrounded by silicone still contained within the fibrous capsule. Compare this appearance with
(E), the same patient at an earlier time, showing the double echogenic interface
Postsurgical breast scar causes interruption in the ultrasound beam at the site of the scar (area of shadowing).
Lumpectomy site after radiation demonstrates an irregular area that appears to be “masslike” without defined borders in the breast.
Fibroadenoma
Malignant thyroid solid mass with spiculation.
Fibroadenoma.
Smooth, ovoid, solid mass with a low-level internal echo pattern.
Lactating breast abscess shows a diffuse mottled appearance of the breast with irregular margins and posterior enhancement.
Suspicious microcalcifications (DCIS) and occult infiltrating ducal carcinoma.
image of pleomorphic (irregular shapes) suspicious microcalcifications identified on screening mammogram in this asymptomatic young woman.
Infiltrating lobular carcinoma.
Papillary carcinoma.
Medullary carcinoma.
Sonogram depicts lobulated mass with ill-defined margins, low-level internal echoes, and a small amount of posterior acoustic enlargement.
Mucinous (colloid) carcinoma.
Tubal carcinoma
Sonogram depicts 0.7-cm, solid, hypochoic mass with irregular, poorly defined margins and posterior acoustic attenuation–common features of carcinoma.
