(A) Mammographically clustered microcalcifications are visible in the MLO and medio-lateral views in the right breast (arrow) but were not visible in the CC view. The max diameter of calcified nodules was 0.68 mm. (B) Transverse chest CT scan adjusted to show the calcifications or the nipple (arrow), the calcifications were measured medial to the nipple (x = 25.93 mm). (C) The calcifications were calculated upper to the nipple (y = 36.35 mm). (D) The calcifications were measured higher to pectoralis major (z = 4.01 mm) and 15.10 mm below the skin surface. (E) Microcalcifications were visible on chest CT scans. (F) The calcifications were successfully removed and confirmed by intraoperative mammography. (G) 3D diagram of breast calcifications localized by chest CT scans. (H) Pathological analysis showing a diagnosis of a low-grade ductal carcinoma in situ (hematoxylin eosin stain, ×40). MLO: mediolateral oblique; CC: cranio-caudal; CT: computed tomography
