    Dynamic Expansion and Contraction of Multiple Sclerosis T2-Weighted Hyperintense Lesions Are Present below the Threshold of Visual Perception

    Recognition of longitudinal imaging changes of MS lesions has substantial implications for clinical management, but changes may remain below the resolution of human perception. In this study, the authors demonstrated that T2-weighted hyperintense lesions undergo dynamic change on MRI, with predominantly enlarging or contracting characteristics, more frequently seen in untreated individuals.

    Macro- and Microstructural White Matter Differences in Neurologic Postacute Sequelae of SARS-CoV-2 Infection

    American Journal of Neuroradiology December 2024, 45 (12) 1910-1918; DOI: https://doi.org/10.3174/ajnr.A8481

    In this cross-sectional study, SARS-CoV-2 infection effects on GM/WM volume, WM microstructure, cognitive performance, and peripheral cytokine concentrations were investigated. The study found that the NeuroPASC group had larger global and regional (prefrontal cortex and hippocampus) cerebral WM volume, more self-reported PASC symptoms, more headaches, lower psychometric performance, widespread higher mean kurtosis in WM microstructure, and different cytokine concentration profiles compared with controls. The authors conclude that immune dysregulation following SARS-CoV-2 infection might result in cerebral WM macrostructural and microstructural injury causing NeuroPASC clinical signs and symptoms.

    Glial Fibrillary Acidic Protein Astrocytopathy: Review of Pathogenesis, Imaging Features, and Radiographic Mimics
    Dhruv Shetty, Sneh Brahmbhatt, Amit Desai, Girish Bathla, Suyash Mohan, Vivek Gupta, Neetu Soni, Prasanna Vibhute and Amit Agarwal
    American Journal of Neuroradiology October 2024, 45 (10) 1394-1402; DOI: https://doi.org/10.3174/ajnr.A8236

    Glial fibrillary acidic protein (GFAP) astrocytopathy is a CNS autoimmune inflammatory disorder characterized by specific antibodies targeting the intracellular filament protein in mature astrocytes. Neuroimaging findings include linear perivascular enhancement in the white matter extending in a radial pattern, periependymal enhancement, longitudinally extensive cord signal changes, intramedullary enhancement, optic neuritis, and papillitis.
