ABSTRACT
Objective:
To explore MRI manifestations of breast encapsulated papillary carcinoma (EPC).Methods:
Data of 18 women with EPC confirmed by surgery and pathology were retrospectively analyzed. Pure EPC (n=7) and EPC with invasion or ductal carcinoma in situ (DCIS) (n=11) were compared.Results:
All 18 EPC presented as masses, and 5 were accompanied by non-mass enhancement. Totally 11 masses were mixed cystic-solid and 7 purely solid, 10 were round/oval and 8 were irregular, 11 were margins circumscribed and 7 were irregular. The median apparent diffusion coefficient (ADC) value of the solid part of EPC was 1.12×10-3 mm2/s. The time-intensity curve (TIC) of EPC was washout in 13 cases and plateau in 5 cases. Delayed-enhancement capsules were observed in 15 masses, included 13 masses showing hypointense capsules on T2WI. The adjacent vessel sign (AVS) was present in 16 masses. No significant difference of clinical nor MRI features was found between pure EPC and EPC with invasion or DCIS.Conclusion:
MRI findings of breast EPC were of certain characteristics, commonly manifested by mixed cystic-solid mass with circumscribed margin, delayed-enhancement capsules presenting hypointense on T2WI, washout TIC type and AVS positive.
