Clear free fluid with through-transmission along the left breast's previous incisional scar site at the level of the fibroglandular/mammary region with the mentioned fluid seen freely peripherally surrounding the ipsilateral Cooper's ligaments (CL) and the mammary parenchymal tissues. The fluid measures approximately 2 cm in depth at the deepest pocket along the inner quadrant, 9 o'clock plane.
The rest of the breast tissues on both lateral and the axillary regions grossly look normal.
