Spine MR imaging of a 35-year-old man with Zika virus infection and Guillain-Barré syndrome presenting with progressive ascending paralysis that evolved to respiratory distress and decreased level of consciousness. The patient had skin rashes preceded by flulike symptoms 1 week before the development of neurologic symptoms. Postcontrast enhancement is seen in the cauda equina nerve roots (arrows) on sagittal (A) and axial (B) T1-weighted spine images following gadolinium-based contrast agent injection. Axial gradient-echo T2-weighted (C) and FSE T2-weighted (D and E) spine images reveal hyperintensity (arrow) in the anterior horns of the cervical (C) and thoracic spinal cord (D).
