Spinal cord infarction: MRI and MEP findings in three cases.

We report findings of magnetic resonance imaging (MRI) in three patients with spinal cord ischemia. While myelography was normal in all three patients, MRI found pathological signal increase on the T2-weighted images in each case. Signal changes in T1-weighted images of hemorrhagic infarction were seen in one patient, and gadolinium-DTPA enhancement because of a disturbed blood-tissue barrier was noted in another. Motor evoked potentials after transcortical magnetic stimulation showed normal latencies with very low amplitudes as a sign of axonal loss in ischemia of the spinal cord.
