Invasive
lobular carcinoma (ILC) is the second most common breast cancer after
invasive ductal carcinoma (IDC). The incidence of ILC has continuously
increased probably due to hormone replacement therapy. There were little
studies to compare the imaging findings of ILC and IDC according to BI-RADS.
The purposes of our study were to characterize the mammographic and MR imaing
features of ILC and to compare these imaging features with those of IDC.
Furthermore, the multiplicity and MRI diagnostic accuracy to detect the
multiplicity apart from the index mass were determined.
