Sonographic features of XXXX .

@entity1 @entity4607 @entity5 @entity0
OBJECTIVE: The purpose of this study was to elucidate the sonographic characteristics of @entity0 . METHODS: Data and sonographic images of 14 @entity0 were retrospectively reviewed. RESULTS: All @entity1 had clinically palpable lumps. The median @entity1 age was 39.5 years (range, 24-60 years). Eleven (78.6%) @entity5 occurred in the right breast, and 3 (21.4%) were in the left. The median @entity5 size measured by sonography was 2.8 cm (range, 1.2-4.9 cm). The median longest transverse dimension-anteroposterior diameter ratio of the @entity5 was 2.44 (range, 1.52-3.73). All @entity5 were oval and compressible with transducer pressure. Thirteen (92.9%) @entity5 were well circumscribed with smooth @entity5 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%) @entity5 had echogenic halos, and 2 (14.3%) had anechoic halos. Ten (71.4%) @entity5 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: @entity0 were well-circumscribed, solid, @entity5 without intratumor microcalcification. The internal echo texture of most @entity4607 is either hyperechoic or composed of mixed echogenicity. Retrotumor acoustic phenomena were absent in most @entity4607 .
