acoustic enhancement and no edge shadowing. • Tiny specks of calcification are appreciated in the lesion. • No probe tenderness over the lesion.• Maintained nonchaotic vascularity in the substance and the

periphery of the lesion. • No perilesional stranding / satellite nodules appreciated. • The lesion rests on the pectoralis bed with maintained interface

and fat planes. • Mobility present on compression .
