title: Mammographically screen-detected asymmetric densities with architectural distortion and normal ultrasound at assessment: Value of MRI as a problem-solving tool.
abstract: Four cases are presented in which asymptomatic clients from an Australian mammography screening programme (BreastScreen ACT) were recalled for assessment of an asymmetric density with possible architectural distortion. In all four women, mammographic work-up was equivocal and ultrasound showed no suspicious correlate for biopsy. It was then doubtful as to whether any significant lesion was present. In all four cases, MRI revealed the presence of malignancy. Breast MRI can be a useful problem-solving tool in the work-up of such cases.
