OBJECTIVE: We describe the sonographic appearance and vascularization of three types of @entity5 , including @entity8146 , @entity24429 , and @entity14972 , and we determine whether vessel density and peak systolic shift can distinguish these @entity5 from @entity2695 and differentiate between the subtypes of these three entities. SUBJECTS AND METHODS: Our study included 16 @entity1 with @entity5 , other than @entity2695 , who were to undergo biopsy. We used gray-scale sonography to identify @entity730 , to evaluate the borders of the lesions to determine whether they were poorly defined or well defined, and to determine the echogenicity relative to the surrounding soft tissue. Doppler sonography served to determine the number of vessels per square centimeter and the peak arterial Doppler shift. Sonographic findings were compared with the final diagnoses established by biopsy. RESULTS: The final diagnoses included five @entity8146 , six @entity24429 , and five @entity28222 . @entity8146 and @entity24429 were ill defined compared with @entity28222 that were well defined. Only one @entity5 , a @entity8146 , fulfilled the diagnostic criteria of @entity2695 . @entity24429 and @entity28222 were the least vascularized, with the lowest vessel density (zero to two vessels per square centimeter) and a relatively low systolic Doppler shift (0.7-1.0 kHz). CONCLUSION: The @entity5 , @entity24429 , and @entity28222 -were distinguishable from @entity2695 on Doppler sonography in all cases except one @entity8146 . Unlike @entity2695 , these lesions should be investigated by biopsy or excision.
