Medial Lemniscus Tract Lesion After High Voltage Electrical Injury: A Case Report

High voltage electrical injuries can cause a variety of damages to the body, including the nervous system. Assessing the extent of this damage, especially in the central nervous system, can be difficult because clinical symptoms don't always match initial radiologic findings. This case report discusses a patient who suffered a high-voltage electrical shock and experienced sensory and motor deficits. Initial MRI scans did not reveal the full extent of the damage, but Diffusion Tensor Imaging (DTI) showed abnormalities in the medial lemniscus tract, a pathway crucial for sensory information. The patient underwent rehabilitation and regained some motor function, but sensory impairments, particularly in proprioception, persisted, hindering independent walking. This case highlights the importance of using advanced imaging techniques like DTI to assess the full extent of neurological damage after electrical injuries.

• 1
  Initial MRI scans of the spine and brain showed no definite abnormalities, despite the patient's significant neurological deficits.
• 2
  Diffusion tensor imaging (DTI) revealed absence of the right medial lemniscus tract, indicating damage to sensory pathways.
• 3
  Delayed cervical MRI showed spinal cord swelling and signal changes, confirming the progressive nature of the injury.
