Clinical presentation and MRI findings in invasive cribriform carcinoma of the breast / 实用放射学杂志

ABSTRACT

Objective To analyze MRI features of invasive cribriform carcinoma of the breast,and to improve the diagnostic accuracy of the disease.Methods MRI of 10 cases with biopsy-proved invasive cribriform carcinoma of the breast in our hospital were analyzed retrospectively.Results 10 cases with invasive cribriform carcinoma of the breast showed unclear boundary.Lesions showed isointensity on T1 WI,and hyperintensity on T2 WI partially with point-like low signal intensity.After contrast administration,the lesions showed heterogeneous enhancement,most of which showed point-like low signal intensity in the lesions,which may be the characteristic manifestations of invasive cribriform carcinoma of the breast.The patterns of time-signal intensity curves were washout type and platform type.Five cases had lymph node metastasis,which may due to the overexpression of PR.Conclusion MRI plays an important role in the diagnosis of invasive cribriform carcinoma of the breast.There is a promising benefit of this radiation-free technique for selecting the optimal therapeutic regimen for this disease.
