Summary of the five patients
| Patient/ sex | Age (years) | Rate of onset | Sensory level1-150 | MRI | Disc disease | Nerve conduction studies/EMG | Outcome |
|---|---|---|---|---|---|---|---|
| 1/F | 14½ | 30 minutes | T10 | Anterior cord hyperintensity T9–conus | Yes | Anterior horn cell fallout | Poor |
| 2/F | 15 | 6 hours | T9† | Anterior and right posterior cord hyperintensity; distal thoracic cord | No | Anterior horn cell fallout left > right; most severe L3–S1 | Moderate left leg most weak |
| 3/M | 14 | 30 minutes | L1 | Hyperintensity anterior distal thoracic cord; right > left | No | Anterior horn cell fallout L5–S1; right > left | Moderate right leg most weak |
| 4/M | 16 | 10 minutes | T6/7 | Hyperintensity anterior cord T3–6; left > right | Yes | Early evidence of anterior horn cell fallout | Moderate |
| 5/F | 15 | “Seconds to minutes” | T11 | Hyperintensity anterior-central cord T9–conus | Yes | Not done | Poor |
