Figure 2 :a-f Magnetic resonance imaging of elder brother: (a) T1w sagittal flexion; (b) T2w sagittal flexion showing reversal of cervical curvature with prominent epidural space from C3-C6 levels; (c) T1w sagittal post contrast in neutral position demonstrates no abnormal enhancement; (d) T1w sagittal post contrast in flexion position demonstrates intensely enhancing epidural space; (e) T2w axial at C5 level shows cord atrophy; and (f) T1w axial post contrast showing abnormal enhancing epidural space
