Benign lesion evaluation: Factors causing the "Stiff Rim" Sign in Breast Tissues using Shear-wave Elastography.

CONCLUSIONS:: The "stiff rim" sign can be helpful for differentiation between benign and malignant lesions. Older patients with a "stiff rim" sign whose benign masses are deep, poorly defined, heterogeneous and have a positive CDFI should be examined more closely to avoid unnecessary false-positives.
ADVANCES IN KNOWLEDGE:: 1.The "stiff rim" sign can be helpful for differentiation between benign and malignant lesions. 2.Positive CDFI, poorly defined margin, heterogeneous internal components , deep depth and older age were significantly associated with the "stiff rim" sign in benign breast lesions.
