Ultrasound demonstrated a poorly defined focus of mixed echogenicity located behind the areolus. Within the mass an anechoic region is seen superficially. The mass has internal vascularity and the anechoic region has increased vascularity seen peripherally. The subcutaneous tissues are thickened, hyperechoic and also demonstrate increased vascularity.
Right breast for comparison showing normal thickness of subcutaneous tissues and absence of hypoechoic breast bud.
