Diffusion-weighted imaging for parasternal lymph nodes in breast cancer: report of two cases

Magn Reson Med Sci. 2011;10(1):53-7. doi: 10.2463/mrms.10.53.

Abstract

We report 2 cases of primary breast cancer with swelling of the parasternal lymph nodes detected on diffusion-weighted imaging (DWI) as small parasternal nodules. After neoadjuvant chemotherapy, DWI showed disappearance of one node but a focus of subtle signal hyperintensity in the other. DWI findings correlated with the results of conventional breast contrast-enhanced magnetic resonance imaging before and after neoadjuvant chemotherapy.
