WebMRI shows restricted diffusion (e.g., high signal on DWI; initially decreased signal on ADC maps, gradually normalizing, then high signal after 10 days); DWI and ADC normalize after 30 days Intraluminal thrombus and … WebIntroduction. The incidence of corpus callosum infarction is low. Giroud et al 1 reported its incidence was 2.7%, while Chrysikopoul et al 2 reported it as 7.9%. Corpus callosum infarction is often combined with other kinds of infarction, and it presents with diverse clinical manifestations, easily leading to missed or delayed diagnosis.
