The aim of this study was to show and correlate the imaging features of breast masses, especially fibroadenomas, using sonoelastography. Two hundred thirty-five patients with 302 breast lesions referred for core needle biopsy participated in the study. All lesions appearing as solid masses on conventional US were included. Out of the included lesions (270), 115 (42.6%) corresponded to histologically confirmed fibroadenomas and 155 (57.4%) to lesions with histologically confirmed diagnoses other than fibroadenomas. These were further subdivided into fibrocystic changes, lesions with low malignancy potential, and malignant lesions. Fibroadenomas were also divided according to histological presentation into three subgroups to allow comparative study based on elastographic scores. All lesions were classified using a four-point scoring system based on ultrasound elastography imaging characteristics. Different presentations were observed for elastographic scores according to histological presentation of fibroadenomas, whereby fibroadenomas with benign characteristics tended to have elastographic classification similar to fibrocystic changes, and complex and hypercellular fibroadenomas had classifications similar to harder lesions. Fibroadenomas are generally classified as category 3 in the BI-RADS lexicon and are the most commonly found lesions in breast biopsies. Sonoelastography can provide additional information to conventional studies and be used as an auxiliary tool in assessing these masses in clinical practice.
