Imaging findings OR Procedure details
A list of 55 patients with a histological diagnosis of radial scar on core biopsy since the introduction of CESM into local practice in 2014 was obtained from the BreastScreen WA database.
Imaging of all 55 patients was reviewed and core biopsy histology of 9 patients who underwent CESM as part of their management pathways correlated with final pathology at excision (results are summarised in figure 1).
In the majority of patients radial scars were seen as stellate opacities on 2D mammography and DBT. CESM appearances included no, faint, stellate and nodular enhancement (Figs 2-6).
Three patients had no correlate on ultrasound and underwent first line stereotactic vacuum biopsy. Of the remaining six, three had ultrasound biopsies followed by vacuum biopsy due to inconclusive results. Only one patient of this small group had invasive malignancy at final surgery.
The ultrasound appearances of radial scars in our cohort were concordant with the literature, and included irregular mass lesions with or without shadowing, round mass lesions or focal shadowing alone (Figs 6,7).
