Acute disseminated encephalomyelitis (ADEM) in a 16-year-old male with a recent history of short febrile illness followed by acute quadriparesis. Sagittal T2W image of the cervicothoracic spine (A) demonstrates multiple poorly defined short segment areas of hyperintensity involving the cervical and thoracic spinal cord (arrows). Axial T2W image of the cervical cord (B) shows that the lesion is involving less than two-thirds cross-section of the spinal cord (arrow). Axial T2W image of the brain (C) of the same patient reveals asymmetrical confluent areas of altered hyperintense signal in bilateral periventricular and subcortical white matter
