Distinct MRI pattern of “pseudoresponse” in recurrent glioblastoma multiforme treated with regorafenib: Case report and literature review

Abstract

Abstract Antiangiogenic agents can induce a distinct MRI pattern in glioblastoma, characterized by a decrease in the contrast enhancement on T1‐weighted images and a simultaneous hyperintensity on T2‐weighted or fluid‐attenuated inversion recovery images.
