Clear skin with uneven echogenicity in both breasts may be a breast enlargement or a normal breast, and should be judged in conjunction with other ultrasound descriptions. Clear skin on both breasts is a normal description, indicating no thickening, retraction, or lack of definition of the skin. Breast hyperplasia can be diffuse or limited. Diffuse hyperplasia appears on ultrasound as thickened glands with structural disturbances and uneven or thickened echogenicity; limited hyperplasia appears as hypoechoic or anechoic nodules. Uneven echogenicity may be caused by mild breast hyperplasia, but there are some normal women with inhomogeneous dense breasts, which show uneven echogenicity due to the presence of breast and glandular tissue in the breast. Patients are advised to combine other descriptions in the ultrasound report and their own symptoms such as breast swelling and pain before and during menstruation to determine whether they have breast enlargement, and to consult a medical professional for specific advice.
