Acute flaccid myelitis in a polio-like syndrome

摘要

A previously healthy 5-year-old boy was admitted for fever, vomiting, and dyspnea, evolving with masticatory automatism, areflexia, and asymmetric flaccid tetraparesis, with preserved sensitivity. Magnetic resonance imaging (MRI) of the spine showed areas with symmetrical T2 hypersignals bilaterally in the anterior horns of the spinal cord, without contrast enhancement, in a “snake eye” sign (Figure 1).
