Anti-glial fibrillary acidic protein antibody and anti-aquaporin-4 antibody double-positive neuromyelitis optica spectrum disorder: A case report

Figure 1 Patient's first brain magnetic resonance imaging. A-D: Four slices of T1-weighted imaging showing low signals in the medulla oblongata; E-H: Four slices of T2-fluid attenuated inversion recovery showing high signals in the medulla oblongata.

Figure 2 Patient’s first brain magnetic resonance imaging. A-D: Four slices of diffusion-weighted imaging showing slightly high and equal signals in the medulla oblongata; E-H: Four slices of apparent diffusion coefficient showing normal value in the medulla oblongata.

Figure 3 Patient’s second brain magnetic resonance imaging. A-D: Low signal intensity on four slices of T1-weighted imaging in the medulla oblongata; E-H: High signal intensity on four slices of T2-fluid attenuated inversion recovery in the medulla oblongata.

Figure 4 Patient’s second brain magnetic resonance imaging. A-D: Slightly high and equal signal intensity on four slices of diffusion-weighted imaging in the medulla oblongata; E-H: Four slices of apparent diffusion coefficient showing normal value in the medulla oblongata.
