Abstract.

The aim of this study was to describe the imaging features of neuroendocrine differentiated breast carcinoma (NEDBC) and to correlate the radiological findings with the clinical and histopathological findings. A retrospective review of the mammograms of 1845 histopathologically proven breast cancer cases revealed five NEDBC. The clinical, imaging, and histopathological findings were analyzed. On mammography, a high-density mass was seen in all patients. The shape of the mass was round in 4 and irregular in 1 patient. The margins were spiculated in 2, indistinct in 1, microlobulated in 1, and partially obscured in 1 patient. On sonography, 4 patients had homogeneously hypoechoic masses with normal sound transmission. In 1 patient the mass was heterogeneously hypoechoic with mild posterior acoustic enhancement. The margins were microlobulated in 2, irregular in 2, and well-circumscribed in 1 patient. Neuroendocrine differentiated breast carcinoma should be included in the differential diagnosis of mammographically dense, round masses with predominantly spiculated or lobulated margins. Sonographically, they mostly present as irregular or microlobulated, homogeneously hypoechoic masses with normal sound transmission.
