Abstract: Objective To evaluate MRI characteristics of solid papillary carcinomas (SPCs) in situ of the breast.Methods A retrospective study included 5 patients with pathologically confirmed SPC in situ was performed.MRI data before operation including conventional MRI,dynamic contrast enhanced MRI (DCE-MRI) and DWI were analyzed.Results All the lesions showed iso/hypointensity on T1 FSPGR sequence,iso/hyperintensity on FSE T2WI sequence and STIR sequence.Mass enhancements were observed for all lesions with oval or irregular shapes on DCE-MRI.The margin of lesions were circumscribed,and internal enhancements were homogeneous or heterogeneous.Time intensity curve appeared a rapid increase in initial contrast phases and platform or outflow types in delayed phases.All the lesions on DWI showed slightly hyperintensity with the ADC value range from 1.34 × 10-3 mm2/s to 1.96)× 10-3 mm2/s.Conclusion MRI manifestations of SPC are characteristics,which may provide valuable information to distinguish SPC in situ from other invasive breast carcinomas.
