Magnetic Resonance Imaging of Autoimmune GFAP Astrocytopathy

The imaging appearance prompted testing for anti-glial fibrillary acidic protein (GFAP) in the CSF, which was positive and confirmed the diagnosis of anti-GFAP astrocytopathy. (D) Sagittal T2-weighted imaging of the cervical spine and (E) thoracic spine reveals confluent and expansile T2-hyperintense cord signal abnormality (arrowheads). Brain magnetic resonance imaging (MRI) showed radial perivascular enhancement extending from the ventricles (Fig 1A, B) with FLAIR hyperintensity (Fig1 C).
