Summary

Serum S100B protein levels may indicate cerebral herniation in trauma patients. Extracerebral sources also contribute to S100B levels, particularly during organ harvesting.

Area of Science:

  • Neurology
  • Biochemistry

Background:

  • Protein S100B elevates in serum and cerebrospinal fluid (CSF) during neurological diseases.
  • The role of S100B in cerebral herniation and extracerebral sources remains understudied.

Observation:

  • A multi-trauma patient experienced cerebral herniation and underwent organ harvesting.
  • Serial serum S100B levels were monitored during herniation and subsequent extracerebral surgery.

Findings:

  • Serum S100B peaked just before cerebral herniation, suggesting a primary cerebral origin.
  • S100B levels increased during organ harvesting, indicating extracerebral protein sources.

Implications:

  • Serum S100B may serve as a biomarker for cerebral herniation in trauma.
