A Case of Asymmetric Nipple Enhancement as an Imaging Precursor to Invasive Ductal Carcinoma.

ABSTRACT

On multidetector computed tomography (CT), it is important to scrutinize the imaged portions of the breasts. In recent years, the dramatic rise in CT imaging has led to the increased detection of incidental breast lesions. We describe a case of invasive ductal carcinoma that presented as stage IV cancer, and retrospective review of prior imaging study revealed asymmetric nipple enhancement on a trauma protocol CT chest acquired three years earlier. This report highlights the importance of being attentive to breast abnormalities on CT performed for indications other than breast disease and additionally focuses on the approach to address abnormal enhancement of the nipple areolar complex (NAC).
