Conflict of interest The authors have no conflict of interest to disclose. A maximum diameter of 2. Color Doppler however is not conceived as a stand-alone examination, but associated with B-mode ultrasound that is quite ecogrqfia as a diagnostic tool, often not requiring Doppler informations. In the first studies it was emphasized as signals were more numerous and stronger in breast tumors [1,2]. Fibroadenomas fibroadenoa a spectrum of features from the well-circumscribed discrete oval mass hypo- or isodense to the breast glandular tissue, to a mass with macrolobulation or partially obscured margin.

Color Doppler ultrasonography for treatment response prediction and evaluation in breast cancer. Here below are presented examples where Color Doppler is valuable.

Ultrasonography of the male breast. Please review our privacy policy. National Center for Biotechnology InformationU. Inflammatory disease Ultrasonography using Color Doppler can depict vascularization in thick-walled cysts, allowing the distinction between old fibrotic cysts with low level internal echoes and abscesses or infected galactoceles, where wall hyperemia is associated with fluid-debris ecogrfaia levels.

Lymphomas may develop multiple feeding vessels that however usually enter through the hilum of the lymph-nodes. Fibroadrnoma color Doppler ha molte altre applicazioni nella valutazione delle patologie della mammella femminile e maschile, che vengono esaminati nel presente articolo. The lesions are not fixed to the surrounding parenchyma and slip around under the palpating hand, hence the colloquial term a breast “mouse”.

Malignant tumors had a tendency to show increased vascularization Fig. Phyllodes tumors Phyllodes tumors are rare fibro-epithelial neoplasms; they may be classified as benign, borderline or malignant according to histological assessment of mitotic index, stromal hypercellularity and pleomorphism, and well circumscribed or invasive borders [6—8]. Ecoyrafia image shows a hypoechoic lesion, with irregularly shaped, acoustic enhancement, within which no vessels were observed at color Doppler but US increased vascularity ecogdafia the mass A, B.

Has color Doppler a role in the evaluation of mammary lesions?

When found in an adolescent girl, the term juvenile fibroadenoma is more appropriate. Incidence decreases after 40 years 4. Sommario Il color Doppler ha un ruolo nella valutazione delle lesioni mammarie? J Magn Reson Imaging. They are benign lesions with minimal or no malignant potential. Fibroadenomas Fibroadenomas that have high stromal cellularity or containing adenosis complex fibroadenomas often show internal vascularization at Color Doppler, differently from the fibrosclerotic or hyalinized ones that may show small peripheral vessels but not internal flow.

Treatment is usually surgical and ranges from simple excision to subcutaneous mastectomy with reconstruction. The efografia is believed to be an end-organ hypersensitivity to normal levels of gonadal hormones. Loading Stack – 0 images remaining.

Giant fibroadenomas of the breast Juvenile or giant fibroadenoma is a rare pathology usually presenting in adolescent and young girls 10—18 years old that is characterized by massive and rapid enlargement of an encapsulated mass [8]. Axillary lymph-nodes The diagnostic value of ultrasonography and color Doppler combined with fine needle aspiration FNA cytology for the detection of non-palpable axillary lymph node metastases in breast cancer patients has a high sensitivity and specificity when there are suspicious features.

US image shows a hypoechoic lesion, with irregularly shaped A ecogrzfia color Doppler shows vessels with irregular course, sinusoids, and arteriovenous shunts B, C. It is the most common breast mass in the adolescent and young adult population 1,3.

A schematic review of color Doppler diagnostic criteria, indicating a benign or malignant lesion, are described. Open in a separate window.

In other instances US may find a complex mass with solid and cystic components Fig. You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Color Doppler ultrasonography permits to assess the features and evolution Fig.

Phillodes tumors scografia B-mode appares as a solid, omogeneous lesion A. The vessel architecture of malignant tumors is known from pathologic studies: Due to their hormonal sensitivity, the fibroadenoma commonly enlarges during pregnancy and involute at menopause. Journal List J Ultrasound v. US scan reveals a hypoechoic mass Fig.

US image shows fibroadejoma hypoechoic lesion, with irregularly shaped, acoustic enhancement, within which no vessels were observed at color Doppler but US increased vascularity around the mass. Cysts Cysts can be divided in: Focal fibrocystic disease may present as a mass or focus lesion sometimes mimicking a malignant breast lesion [6,7]. The evaluation of tumor response to neoadjuvant chemotherapy by means of physical examination, ultrasonography, and mammography has limitations on the basis of its morphological approach and the impossibility of distinguishing residual caner from fibrosis.

Has color Doppler a role in the evaluation of mammary lesions?

Predicting clinical behaviour of breast phyllodes tumours: Typically seen as a well-circumscribed, round to ovoid, or macrolobulated mass with generally uniform hypoechogenicity. Color Doppler ultrasound has many other useful applications in the evaluation of diseases of the female and male breast, that are reviewed in the paper. Articles Cases Courses Quiz. Calcification may also present as crushed stone-like microcalcification which makes differentiation from malignancy difficult.

When a lesion has the typical features of a fibroadenoma on ultrasound and there are no clinical red flags they can be safely followed clinically. Malignant tumors have a tendency to show increased vascularization, but avascular tumors may be found as well as hypervascular benign tumors.

These lesions are easily biopsied under ultrasound guidance.
