Imaging from study of Guillain-Barré syndrome and visual impairment associated with emerging Oropouche virus lineage, Brazil, 2024. A) T2-weighted magnetic resonance imaging of lumbar spinal cord. Arrows indicate nerve root edema. B) T1-weighted magnetic resonance imaging of brain with contrast. Arrow indicates enhancement of right facial nerve. C, D) Optical coherence tomography of right eye (C) and left eye (D) revealed bilateral loss of ganglionic cells in the papillomacular bundle, shown in white on the circle graphic.
