Fig. 10From: MRI features of myelin oligodendrocyte glycoprotein antibody disease: a descriptive study—how it differs from neuromyelitis optica spectrum disorders and multiple sclerosisAtypical presentations of MOGAD. a The case illustrates isolated aseptic meningitis in a 20-year-old man with MOG antibody disease. Axial post-contrast T1 weighted MR image shows contrast enhancement in the left frontal and parietal lobes. b The case illustrates isolated unilateral limbic encephalitis in a 54-year-old man with MOG antibody disease on relapse. Axial T2 FLAIR MR image shows hyperintensity in the left hippocampal region. c Axial ASL image of the aforementioned case of isolated unilateral limbic encephalitis in a 54-year-old man with MOG antibody disease shows increased cerebral blood flow in the left mesial temporal lobeBack to article page
