Summary
A rare case of diffuse axonal injury (DAI) occurred in a teen after a jet ski accident, despite no initial head trauma. Delayed symptoms and full recovery highlight the need for monitoring after high-velocity incidents.
Area of Science:
- Neurology
- Trauma Medicine
- Radiology
Background:
- Diffuse axonal injury (DAI) is typically associated with direct head trauma.
- High-velocity accidents can cause significant internal injuries.
Observation:
- A 16-year-old female sustained bilateral lower extremity fractures from a jet ski accident.
- No immediate signs of head trauma were present.
- Coma developed 30 hours post-accident, with MRI confirming DAI.
Findings:
- This case presents an unusual instance of DAI without direct head impact.
- Delayed onset of neurological symptoms (coma) was observed.
- The patient experienced a full recovery without sequelae.
Implications:
- Patients involved in high-velocity accidents require observation for DAI, even without initial head injury signs.
- This case expands the understanding of DAI mechanisms and presentation.
- Early recognition and monitoring are crucial for managing potential DAI after trauma.
