Adenomyoepithelioma of the breast (AB) is rare. This study details its ultrasonography and mammography imaging characteristics, noting oval nodules and vascularized patterns are common, aiding radiopathologic correlation.
Area of Science:
- Radiology
- Oncology
- Pathology
Background:
- Adenomyoepithelioma of the breast (AB) is an uncommon biphasic tumor.
- Radiologic findings for AB are sparsely documented in literature.
Purpose of the Study:
- To analyze the characteristic imaging findings of Adenomyoepithelioma of the breast (AB) on ultrasonography (US) and mammography.
- To improve radiopathologic correlation for AB diagnosis.
Main Methods:
- Retrospective descriptive study of 13 histologically confirmed AB cases.
- Analysis of US and mammography findings using Breast Imaging-Reporting and Data System (BI-RADS).
Main Results:
- On US, lesions were typically oval nodules (12/13), often hypoechoic (8/13) and vascularized (11/13).
- Margins varied: circumscribed (8/13), angled (3/13), microlobulated (2/13).
- Complex solid-cystic echo patterns were observed in 5/13 lesions.
Conclusions:
- Imaging findings for AB are not specific.
- Familiarity with AB imaging characteristics is crucial for radiologists to facilitate accurate radiopathologic correlation.
