| Summary: | The aim of this study was to evaluate the diagnostic value of the ultrasound B-mode
imaging in the differentiation diagnostics of solid lesions in the breast in relation to
the pathomorphological verification. From January to July 2010, 375 ultrasound breast
examinations were conducted. The study enrolled 80 women aged 17–83, with 99 solid,
focal lesions present in breasts, which were qualified for pathomorphological verification
on the basis of the ultrasound examination. All patients underwent: the interview, physical
examination, ultrasound examination and sonoelastography. The ultrasound features of
the lesions, their vascularization patterns in the Doppler examination as well as the adjacent
tissues were determined. Next, the focal lesions were categorized according to the
BIRADS-US classification. The obtained results were analyzed statistically. In the group
of 80 patients, 99 focal, solid lesions in breasts were visualized, including 39 neoplastic,
malignant lesions (group I) and 60 lesions of benign nature (group II). The malignant
lesions were often characterized by: greater size, irregular shape (34/39), prevalence of
the anteroposterior dimension over the lateral‑lateral dimension (22/39), acoustic shadowing
(20/39), the margins not well-circumscribed (37/39), spiculated margins (16/39)
and the presence of calcifications (14/39). The benign lesions were much more often
hyper- and isoechogenic (14/60). In group I the lesions more often demonstrated the
features of increased vascularization (29/39) and the presence of irregularly shaped vessels
(23/29). This vascularization more often originated in the adjacent tissues. In the
surroundings of the malignant neoplastic lesions, the presence of edema (16/39) and skin
thickening (6/39) occurred more frequently and the abnormal axillary lymph nodes were
more often diagnosed. The lesions of group I were assigned to the following BIRADS
categories: BIRADS-US 4 (9 lesions) and BIRADS-US 5 (30 lesions). In group II, there
was a prevalence of BIRADS-US 3 and 4 categories (58 lesions) and 2 lesions were classified
to BIRADS-US 5 category. In the statistical analysis of the models based on BIRADS
classification, it was demonstrated that BIRADS 4 showed the highest sum of sensitivity
and specificity values of 173.6% in differentiation of the character of focal lesions in the
breast (sensitivity 76.92%, specificity 96.67%). |
