📄 Abstract: Neuro-Behçet's disease (NBD) is a chronic heterogenous autoimmune disorder. It may involve central or pripheral nervous system but rarely shows spinal cord involvement (SCI). Bagel Sign is a unique sign of SCI due to NBD. It is a central T2W hyperintense lesion with a hypointense core on axial magnetic resonance imaging (MRI). This sign may be a complete or an incomplete ring with or without post-contrast enhancement. Here we report a patient with NBD whose primary presentaion was transverse myelitis. A 14-year-old patient was admitted due to triparesis and urinary retention. He had T2W hyperintensities from the left basal ganglion down to the T10 level. A similar anteromedial spot has been described in anterior spinal cord infarction which favors an ischemic pathogenesis for NBD. To our knowledge this is the first report of Bagel Sign and longitudinally extensive transverse myelitis with gray matter involvement.
