Purpose: To evaluate the ultrasonographic (US) features that are helpful in differentiating malignancy from benign tumor for non-palpable, oval, circumscribed breast lesion.
Materials and Methods: During about 30 month period, 14 non-palpable, oval, circumscribed breast cancers in 14 patients were found from 2151 US-guided core biopsies. Fourteen malignant tumors were ten invasive ductal carcinomas, two mucinous carcinomas and two ductal carcinoma in situ. Twenty-five benign tumors in 25 patients (23 fibroadenomas, 2 intraductal papillomas) were included for control groups. US images more than 3 different planes per one lesion were saved as a bitmap file. The images of the 39 lesions were randomized and two radiologists analyzed according to the BI-RADS lexicon without knowledge of the pathology and decisions were reached by consensus. The shape (oval, round, irregular), orientation (parallel, not parallel), margin (circumscribed, indistinct, angular, microlobulated, spiculated), boundary (abrupt interface, echogenic halo), echo pattern (anechoic, hyperechoic, complex, hypoechoic, isoechoic), posterior acoustic features (no posterior, enhancement, shadowing, combined pattern) and surrounding tissue (duct changes, cooper’s ligament changes, edema, architectural distortion, skin thickening or retraction) of the tumor were provided. The US findings were compared between benign and malignant tumors.
Results: Echogenic halo was more common in malignant tumor (7/14, 50%) than in benign tumor (2/25, 8%) (p=0.005). The shape, orientation, echo pattern, posterior acoustic features, and surrounding tissue of the tumor were not different in those two groups.
Conclusion: There is a tendency for a circumscribed cancer to combine with an echogenic halo. It is helpful to search for an echogenic halo to identify a cancer for evaluation of non-palpable, oval, circumscribed breast lesion.
