Ultrasound appearance of breast fibroadenoma

A woman's breast is a very soft place. It is not only a symbol of femininity, but also an important part of the body for women to raise the next generation, because when a woman is pregnant and giving birth, her breasts will secrete milk for the baby to drink. However, older women are more likely to develop breast fibroadenoma, a benign tumor disease on the breast. So how does breast fibroadenoma appear on ultrasound?

Generally, no special preparation is required and the examination can be carried out at any time.

Clinical significance

A nodule was accidentally found in the breast. It has a capsule, a smooth surface, a hard texture, but can slide, and is round or oval in shape. Single disease is common, but multiple diseases may also occur. Ultrasound showed that the tumor was round or oval in shape, low-echoic, homogeneous, capsule-encapsulated, and movable. The color Doppler peak is 15-30 cm/s, and the resistance index is 0.5-0.6. Based on the above characteristics, the diagnosis is generally correct. Atypical fibroadenomas should be differentiated from breast cancer. If there are difficulties, a needle biopsy is still necessary.

The patient lies in supine position or lateral position when necessary, with arms raised to fully expose the breast. Direct examination is performed with longitudinal, transverse, and oblique scans of each quadrant of the breast. If a lump is found, its size is measured, and its shape, location, boundary, presence of capsule, internal and posterior echoes are observed. The probe is used to apply pressure or the patient is asked to change position, and attention is paid to any changes in the shape of the lump. Color Doppler is used to observe whether there are blood flow signals inside and around the lump.
