Objective:

To summarize and compare the ultrasonographic features of granulomatous lobular mastitis (GLM) and infiltrating lobular carcinoma of the breast (ILC) for improving the differential diagnosis of them.

Methods:

The ultrasound images of 28 GLM lesions and 58 ILC lesions in Peking Union Medical College Hospital were retrospectively analyzed. The clinical data and ultrasound images of the lesions were compared and analyzed between the two groups

including morphology

aspect ratio

boundary

halo

ductal dilatation

fluid area

calcification.

Results:

There w

ere significant differences between the two groups in clinical manifestations (age of onset

redness

swelling

heat and pain

etc.) and ultrasonographic features (morphology

internal catheter expansion

liquefaction area and calcification) (

P

＜0.05).

Conclusion:

Compared with ILC

GLM is more likely to appear with liquid area

duct dilatation

rich blood flow. Comprehensive analysis of ultrasound imaging and clinical manifestations helps to improve the differential diagnosis of them.
