From: Can DWI-MRI be an alternative to DCE-MRI in the diagnosis of troublesome breast lesions?
A 31-year-old female presented with right breast lump and pain. Mammography (A) showed two large retroareolar well-defined lesions of mixed densities predominantly hyperdense, and ultrasound (B) showed right retroareolar large well-defined mass of mixed echogenicity predominantly hypoechoic with posterior acoustic shadowing. Sonomammography revealed BIRADS 3. MRI axial images showed right large well-defined retroareolar mass showing heterogeneous signal on T1 (C) with elements of hyperintensity and intermediate signal on T2 WIs (D). MRI axial dynamic THRIVE sequence and subtraction image (E) showed right retroareolar well-defined mass with marginal contrast uptake. Time/signal intensity analysis (F) of ROI showed continuous rising curve pattern (type I) with SI % of 35%. Diffusion sequence b 850 (G) and post-processing ADC map (H) showed mixed signal intensity with foci of restricted diffusion in the right retroareolar mass. ADC value for ROI was 0.9 × 10−3mm2/s. DCE-MRI revealed BIRADS 2, but DWI-MRI gave suspicious findings BIRADS 4. Pathology revealed fibroadenoma
