Abstract
OBJECTIVE: The purpose of this study was to elucidate the sonographic characteristics of breast hamartomas. METHODS: Data and sonographic images of 14 breast hamartomas were retrospectively reviewed. RESULTS: All patients had clinically palpable lumps. The median patient age was 39.5 years (range, 24-60 years). Eleven (78.6%) tumors occurred in the right breast, and 3 (21.4%) were in the left. The median tumor size measured by sonography was 2.8 cm (range, 1.2-4.9 cm). The median longest transverse dimension-anteroposterior diameter ratio of the tumors was 2.44 (range, 1.52-3.73). All tumors were oval and compressible with transducer pressure. Thirteen (92.9%) tumors were well circumscribed with smooth tumor margins, and 1 (7.1%) had indistinct margins. The internal echo texture was hyperechoic in 6 (42.9%), mixed (heterogeneous) echogenicity in 5 (35.7%), and isoechoic in 3 (21.4%). Four (28.6%) tumors had echogenic halos, and 2 (14.3%) had anechoic halos. Ten (71.4%) tumors had no retrotumor acoustic phenomena. Two (14.3%) had bilateral edge shadowing; 1 (7.1%) had posterior enhancement; and 1 (7.1%) had a mixture of enhancement and shadowing. CONCLUSIONS: Breast hamartomas were well-circumscribed, solid, oval tumors without intratumor microcalcification. The internal echo texture of most hamartomas is either hyperechoic or composed of mixed echogenicity. Retrotumor acoustic phenomena were absent in most hamartomas.
