Figure 9. Ultrasonographic features of the Fistula Stage in GLM. (A) shows a duct-like hypoechoic structure beneath the nipple (N) extending toward the areolar skin. The inner wall of the duct is thickened (thin arrow), and a skin ulceration is visible at the areola (asterisk); (B) demonstrates an irregular sheet-like hypoechoic area extending from the glandular layer through the adipose tissue into the subcutaneous region, with a visible skin ulceration at the surface (asterisk).
