Spinal cord lesions in heat stroke.

G Delgado, T Tuñón, J Gállego

    Journal of Neurology, Neurosurgery, and Psychiatry
    |October 1, 1985
    PubMed
    Summary

    Classic heat stroke can cause severe spinal cord damage, leading to paralysis and autonomic dysfunction. This case highlights the extreme sensitivity of spinal motor and vegetative neurons to hyperthermia.

    Area of Science:

    • Neurology
    • Pathology
    • Environmental Medicine

    Background:

    • Heat stroke is a severe form of hyperthermia with significant morbidity and mortality.
    • Understanding the specific neuropathological consequences of heat stroke is crucial for clinical management.
    • This report details a fatal case of classic heat stroke, focusing on clinical and pathological findings.

    Observation:

    • The patient presented with flaccid quadriplegia, anhidrosis, and sphincter disturbance post-heat stroke.
    • Autopsy revealed severe pathological lesions primarily in the anterior and intermedio-lateral horns of the spinal cord.
    • Hyperthermia was identified as the sole demonstrated physiopathological mechanism.

    Findings:

    • The spinal cord's anterior and intermedio-lateral horns, containing motor and vegetative neurons, exhibited the most severe damage.
    • The clinical presentation correlated with the observed spinal cord pathology.
    • Hyperthermia was confirmed as the causative factor for the observed lesions.

    Implications:

    • Motor neurons and vegetative neurons within the spinal cord appear particularly vulnerable to extreme heat.
    • These findings suggest a specific neurotoxic effect of hyperthermia on spinal cord function.
    • Further research into the cellular mechanisms of heat-induced neuronal injury is warranted.
