Intracystic mural nodules of the breast: benign versus malignant; a multidisciplinary imaging and management approach

This case report illustrates the presence of intracystic mural nodules within the breast, a benign proliferative disorder associated with the fibrocystic spectrum: papillary apocrine metaplasia. The aim of this paper is to provide a comprehensive understanding of the physical and histological attributes of benign intracystic mural nodules, and the ability to distinguish these from a malignant papilloma and carcinoma. Also, the technical and patient considerations, as well as the appropriate imaging and interventional methods required to ensure correct patient management pathway are discussed, extending into an analysis of the psychological effects felt by patients undergoing assessment.
