摘要

Purpose

Contrast-enhanced magnetic resonance imaging (CE-MRI) is an essential imaging modality for planning breast cancer surgical procedures. However, CE-MRI findings in Paget’s disease of the breast (PD) have not been studied extensively. This study aimed to elucidate the CE-MRI findings of PD and assess their role in surgical treatment planning.

Methods

Twelve patients with PD who underwent surgery between 2011 and 2023 were retrospectively analyzed.

Results

The average patient age was 73.8 ± 14.3 years. CE-MRI detected enhanced areas in the nipple-areola complex (NAC) and/or surrounding skin in all patients. Additionally, 6 patients showed enhanced areas within the breast, suggesting ductal spread into the breast. Of these, 1 patient underwent breast-conserving surgery (BCS), and 5 opted for mastectomy. Pathology confirmed the extent of ductal spread of PD, as indicated by CE-MRI. Among the 6 patients who did not have an enhanced area in the breast, 3 underwent BCS or central lumpectomy including NAC, and 3 chose mastectomy based on the patient's preference, and no malignant foci were observed in the breast.

Conclusion

CE-MRI effectively evaluated the ductal spread of PD in the breast, demonstrating its utility in guiding the selection of surgical procedures.
