Fig. 2. Pre-tracheal hydrodissection-assisted core needle biopsy (CNB) of entirely calcified nodule. (A) A 57-year-old female patient presented with an entirely calcified nodule (*) with dimension of 7×12×13 mm on the left side of the thyroid gland near the trachea. (B) Pre-tracheal hydrodissection was performed to create safe margin (dotted lines) between the trachea and the target nodule (*). (C) Two CNB specimen were acquired and underwent subsequent mammography magnification examination, which demonstrated a thick calcified line (arrow).
