FIG 1. August 1994. Sagittal fast spin-echo T2-weighted (5000/112/2) (TR/TE/excitations) image shows enlarged and inhomogeneously hyperintense spinal cord from the cervico-occipital junction to the upper dorsal region (A). Sagittal spin-echo T1-weighted (460/17/2) images with gadopentate dimeglumine show peripherical enhancement (B). After seven days of corticosteroid therapy, spinal cord enlargement has decreased (C). Eight months later (April 1995), the cord is normal (D)
