title: New preoperative MRI marking technique for a patient with ductal carcinoma in situ.
abstract: We herein present a case of non-palpable ductal carcinoma in situ (DCIS) treated with successful breast-conserving surgery (BCS) using MR markers made with commercially available materials in the supine position. The patient was a 40-year-old woman found to have a non-mass lesion by routine screening ultrasonography (US). The margin of the lesion was unclear by the US examination, whereas contrast-enhanced MR mammography (MRM) revealed a clear margin of the lesion. After the resection line was determined by under US guidance, the area was marked by original markers for MRI using the pills of Breath Care inside a Penrose drain. MRM was performed in the supine position (supine MRM), which is similar to the posture used for surgery. The lesion was located within the resection area, but it was not at the center of the resection area; thus, the resection lines were modified using information obtained by MRM. The histological evaluation of the BCS specimen demonstrated a wide extension of the DCIS. The lesion was located at the center of the resection specimen, and the surgical margin was free. In conclusion, since our procedure can be performed easily, it is useful for evaluating the extent of the lesion as determined by the US examination in difficult cases.
