MR imaging findings in delayed reversible myelopathy from lightning strike.
Delayed spinal cord injury following high-voltage electrical injury is a rare but well-documented phenomenon. The MR imaging features of this entity, however, have not been well documented. We report the MR imaging findings in a case of delayed sensory and motor deficits following a lightning strike. MR imaging revealed hyperintense signal within the cord on T2-weighted and STIR images extending from C1 to C3. Axial images localized the hyperintense signal to the posterolateral region of the spinal cord bilaterally. Follow-up MR imaging 6 weeks later demonstrated resolution of abnormal cord signal intensity.
