Wire Localization of Nonpalpable Breast Lesion with Magnetic Resonance Imaging

Abstract

INTRODUCTION: The Magnetic Resonance Imaging (MRI) has a sensitivity of almost 100% in invasive breast cancer visualization and it s well recommended for patients with dense breasts, high risk for breast cancer, to stage patients with breast cancer, to investigation of multicentricity and to investigation of occult breast carcinoma. However, isn t indicated as mammary method of routine screening. REPORT: SSA, 34 years, with an unespecific palpable area of 60mm in left breast on phisical exam, ultrassound core biopsy of a lump with 13mm x 12 mm diagnosed breast cancer in left side. The left breast tumor hasn t translation in mammogram and MRI was performed to avaliate the size of the tumor, which revealed a lesion of 90mm in left side, with rapid and early enhancement and wash-out curve. In rigth side, in retroareolar region showed a non-mass like enhancement and BI-RADS-MRI 4B. The lesion was needled by MRI because has not translation by another imaging method and the surgical anatomopathological showed usual ductal hyperplasia, microcysts and focal adenosis, without evidence of microcalcifications. DISCUSSION: MRI is a precious method in the preoperative evaluation of young patients with breast cancer, showing some lesions not visualized in other imaging methods and can be used in mammotomy guided biopsies and pre surgical wired localization.
