50-year-old woman with history of left parieto-temporo-occipital glioblastoma multiforme and new abnormal enhancement on follow-up imaging after surgery and proton beam irradiation therapy. 50-year-old woman with history of left parieto-temporo-occipital glioblastoma multiforme and new abnormal enhancement on follow-up imaging after surgery and proton beam irradiation therapy. A, Arrows on this precontrast axial T1-weighted image illustrate the location of abnormal enhancement. B, Arrows on this postcontrast axial T1-weighted image illustrate the spreading wavefront appearance along one of the dominant borders of the lesion; subependymal involvement that extended up to involve the corpus callosum is also observed. Biopsy of a portion of the abnormality yielded recurrent tumor. Mark E. Mullins et al. AJNR Am J Neuroradiol 2005;26:1967-1972 ©2005 by American Society of Neuroradiology
