Apport de l’IRM dans les écoulements mamelonnaires pathologiques : analyse de 50 cas

Abstract

PurposeTo determine the role of MRI in the evaluation and management of patients with suspicious nipple discharge and normal mammographic and US evaluation. Patients and methodsA total of 50 patients with suspicious nipple discharge and normal mammographic and US evaluation prospectively underwent MRI. The first 16 patients underwent routine breast MRI, while MR-ductography with image fusion at the console was added for the last 34 patients. ResultsIn 22 of 25 high-risk and malignant lesions, MRI showed enhancement whereas it was normal in three cases. In 25 benign cases (resolution of discharge/benign non-proliferative breast disease), MRI was negative in 22 cases and falsely positive in three cases. ConclusionIn this clinical setting, MRI shows excellent sensitivity, PPV and NPV. A negative result on MRI would support clinical follow-up as opposed to surgery.
