“…Calcification on MMG is reportedly rare in patients with NE-DCIS 1,7,9 , and our cohort showed the same trend, with no calci cation observed in any patient with NE-DCIS by MMG. In contrast, calci cation was observed in 43 60.1 patients with non-NE-DCIS, thus there was a significant difference in the rendering rate of calcification between NE-DCIS and non-NE-DCIS cases.…”

“…According to consensus MRI ndings for DCIS, the most common lesion is a non-mass-type 59 of patients , followed by mass-type 14 , and focus-type 12 7 . In our study, nonmass-type lesions were most common in patients with non-NE-DCIS 76.1 , and mass-type lesions accounted for only 16.9 .…”

Although we did not analyze the ultrasound ndings, hypoechoic lesions with a relatively distinct border are often found in NE-DCIS, with images characteristic of duct ectasia and lesions showing abundant blood ow on color Doppler imaging 1,5,7,9 .

Neuroendocrine ductal carcinoma in situ of the breast NE-DCIS was recently recognized as a special subtype of DCIS, although the diagnostic criteria for NE-DCIS are yet to be established. DCIS is defined as the immunohistochemical expression of neuroendocrine markers chromogranin A and / or synaptophysin in over 50 of tumor cells. Here, we investigated whether there are signi cant differences in magnetic resonance imaging MRI ndings between NE-DCIS and non-NE-DCIS. The study sample comprised 8 lesions in 7 patients with breast NE-DCIS and 71 lesions in 69 patients with non-NE-DCIS who underwent preoperative MRI and histopathological diagnosis at our hospital from June 2010 to June 2012. The patients were females aged 34-85 years. We examined the lesion type, pattern of time-signal intensity curve TIC on dynamic contrast-enhanced MRI DCE-MRI , presence or absence of bloody duct ectasia delineation, and presence or absence of calci cation on mammography MMG. Mass-type lesions were significantly more common in breast NE-DCIS than in non-NE-DCIS on MRI. On DCE-MRI, the TIC washout pattern was more commonly observed in NE-DCIS than in non-NE-DCIS, and although there was no signi cant difference in the rate of bloody duct ectasia delineation, it was relatively more common in NE-DCIS. MMG revealed a signi cant difference in calci cation between non-NE-DCIS 60.1 and NE-DCIS 0. Mass-type lesions and TIC washout pattern are signi cantly more common in patients with NE-DCIS than in those with non-NE-DCIS on MRI and DCE-MRI.
