Estudio del complejo aréola-pezón con resonancia magnética y microbobinas

Abstract

ObjectiveTo evaluate the use of magnetic resonance imaging (MRI) with microcoils in the study of the nipple-areolar complex and its importance in the examination algorithm in cases of clinically significant discharge (thelorrhagia). Patients and methodDescriptive study of a group of patients with single-pore nipple discharge by using commercially available microcoils, with and without contrast, in a magnetic resonator. Three-dimensional reconstruction of the findings, with the very high resolution provided by microcoils, was shared with the surgeon, and surgical resections were analysed with the pathologist, when indicated, from November 2013 to March 2015. ResultsTwenty-five patients were included. Of these, benign lesions were found in 15 patients (6 central papillary tumors, 4 galactoceles, 2 papillary proliferations without atypia, 1 cystic mastopathy, 1 abscess, and 1 fibroadenoma). Carcinomas were found in 9 patients (36%), mostly with micro papillary and cribriform patterns. Most nonmalignant lesions (papillary tumours) were associated with dilated ducts, with haematogenous or serous signs and filling defect due to proliferation and gadolinium enhancement. Most malignant lesions showed less dilated vessels, mainly with haematogenous signs and non-mass enhancement of clustered rings whose volume reconstructions showed them as «sponge or corals». ConclusionsThe method is simple and effective and could be used as a first line indication for the treatment of thelorrhagia and in the global examination of the nipple-areolar complex.
