(A) Straightening of a mildly tortuous duct and gland during intraductal probing. The duct is noticeably tortuous in image before probing (black lines closely parallel the central ducts). (B) 4 mm probe has been advanced and is visualised within the duct tract. Note the duct and gland appear significantly straighter and the interglandular connective tissue area (arrows in A–C) seems reduced. (C) Immediately after probe withdrawal, persistent straightening of the proximal duct and gland. (D) At 2-month follow-up. The same gland with configuration of gland and interglandular tissue restored to near pre-probing appearance suggesting interglandular tissue is spongy, able to be compressed and re-expand allowing duct and gland flexibility.
