Purpose:Complex sclerosing lesions (CSL) of the breast are the result of entrapment and distortion of benign ductal and lobular components by fibroelastotic scars. They often mimic invasive breast carcinoma (IBC) on imaging and pathologic examinations resulting in misdiagnosis. This study is to compare the magnetic resonances imaging (MRI) and pathologic features of those lesions. Materials: 27 cases of surgically excised and pathologically confirmed CSL cases and 33 IBC cases that also have MRI available are identified from our hospital database. The patients demography, pathologic and MRI features are analyzed and compared. Results: The average patient age for the CSL group is 45.7±8.4 years and the IBC group is 57.8±14.2 years (p=0.000). The average diameter of CSL is 1.19±0.64cm and invasive carcinoma is 2.14±1.35cm (P=0.001). Similarly, 59.3% of CSL and 69.7% of IBC cases are described on both image and pathology reports as "ill-defined" or "speculated". Comparing MRI features of the 2 groups, we found that 25 out of 33 IBC cases (75.8%) showed low signal intensity while only 13 out of 27 CSL cases (48.1%) showed low intensity on T1W (p=0.027). No statistical differences between the two groups on sagittal T2-weighted (T2W) signal intensity (p=0.386) and on short inversion time inversion recovery (STIR) (p=0.093). 19 out of 27 CSL cases (70.4%) showed type I time intensity curve (TIC) pattern and 7 out of 27 CSL cases (25.9%) showed type Ⅱ TIC patterns while 20 out of 33 IBC cases (60.6%) showed type Ⅲ TIC pattern (p = 0.000). The mean apparent diffusion coefficient (ADC) value for CSL group is 0.00137 mm2/s and for IBC group is 0.00104 mm2/s (P=0.003). In addition, 3 out of 33 IBC cases showed rim enhancement while non CSL cases did. Conclusions: Our data suggest that compare to CSL, IBC tend to occur in older women with larger lesional diameter. IBC often have lower signal intensity on T1W imaging, less than 0.0012 mm2/s ADC value and mostly type Ⅲ TIC pattern. While T2W and STIR data as well as the image shape or boarder of the lesions are less useful in distinguishing the CSL from IBC.
