Overview

Breast ultrasound is the first imaging modality in patients with palpable masses under age 40 years old and is adjunctive modality to mammography for patients older than 40 years. Breast sonography is a type of imaging used to confirm abnormal findings on mammography or MRI. Breast ultrasound improves breast cancer detection rate.

Ultrasound

Ultrasonographic finding of common breast lumps[4]
Types of breast lumps Characteristic findings
Cyst
  • Simple cyst: Well-circumscribed, anechoic contents, thin echogenic external capsule, enhanced through-transmission, subtle acoustic shadowing at the ages
  • Complicated cyst: Although not purely anechoic, diffuse echoes of low amplitude
  • Complex cyst: Well-circumscribed anechoic mass with solid components
  • Cysts with sediments: an anechoic mass containing sharp margins and posterior hyperechoic sediment
Abscess
  • Hypo-anechoic mass with irregular margins and peripheral hypervascularity
Mastitis
  • Subcutaneous and parenchymal edema with small fluid collection and diffuse hypervascularity
Galactocele
  • Moderately echogenic contents with fat spreading heterogenously in the liquid component
Seroma
  • Anechoic or diffuse low-level echoes or thin fibrin septation.
  • Blood presence may result in sediment, pseudonodule, wall-thickening, and coarse septa formation
Liponecrosis
  • A nodule with same feature as complex cyst
Hemangioma
Fibroadenoma
  • Classic fibroadenoma: Elliptic or lobulated shape, horizontal orientation, isoechoic or mildly hypoechoic echotexture, well-defined curvilinear margin with thin echogenic capsule, unaltered US beam transmission beyond the lesion, and subtle acoustic shadows on both sides of the nodule
  • Complex fibroadenoma: Heterogenous echotexture lesion with microcysts (apocrine metaplasia) or small hyperechoic areas (sclerosing adenosis)
Phyllodes tumor
  • Moderately hypoechoic nodules with pseudocapsule, without posterior acoustic shadowing, sometimes pseudocystic spaces are so compressed which seem like hyperechoic striations
Hamartoma
  • Heterogenous appearance with mixture of isoechoic (adipose tissue/glandular lobules) and hyperechoic areas (fibrous tissue)
Papilloma
  • Intraductal papilloma: Well-circumscribed subareolar duct ectasia with an iscoechoic, microlobulated surface on nodule
  • Intracystic papilloma: A cyst with prominent mass
Ultrasound image of breast abscess - The sonographic feature of breast abscess in lactating mother presenting with right breast lump.There is a lobulated collection with mobile echoes mainly in upper and inner quadrant; extending from 11 o'clock to 3 o'clock.

Ultrasound image of breast fibroadenoma -Oval shaped hypodense lesion, no internal vascularities seen on color Doppler. Source: Case courtesy of Dr Hani Salam, from Radiopedia
Ultrasound image of breastinvasive lobular carcinoma -There is a lobulated, hypoechoic lesion involving upper quadrants in the retro-periareolar region. Approximate size of the lesion is 58 x 47 x 25 mm. The lesion abutts pectoralis muscle. There are few tiny echogenic foci in the lesion - calcifications. Lesion shows angular margins. There is no posterior acoustic enhancement/shadowing/ significant vascularity. Rest of the breast shows predominantly fatty parenchymal echopattern. There is no ductal dilatation. There is no axillary or internal mammary adenopathy. Pectoralis muscle is normal. Source: Case courtesy of Dr Maulik S Patel, from Radiopedia
