Radiation neuropathy. Radiation neuropathy. A 69-year-old woman with a history of breast carcinoma and external beam radiation therapy 2 years before imaging presented with worsening right-arm sensory deficits. Coronal (A) and axial (B) 3D STIR SPACE images show a T2 hyperintense right-sided brachial plexus (arrows) with minimal linear enlargement in the area of the radiation field. No focal mass is visualized. S.K. Thawait et al. AJNR Am J Neuroradiol 2011;32:1365-1372 ©2011 by American Society of Neuroradiology
