Figure

  • Fig. 1. Sagittal (A) and axial (B, C3 level) images from cervical spine T2-weighted magnetic resonance imaging. An extensive syrinx had developed within the spinal cord (from C2 to T10) (arrows). Median somatosensory evoked potentials (SEPs) (C) were normal for N9 but small for N13 and N19. The tibial SEP (D) was normal for P37 bilaterally in the lower limbs. *Represent the locations of each potential.
