Vasospasm following low-velocity penetrating pediatric intracranial trauma
Bibliographic record
Abstract
BACKGROUND: BB guns or non-powder guns created in the modern era are able to reach exceedingly fast velocities as a result of advances in compressed-gas technology. While missile penetrating trauma has been well documented in neurosurgical literature, penetrating intracranial injury secondary to non-powder guns, along with their associated complications and treatments, is not well described, and even less so in the pediatric population. CASE PRESENTATION: Here, we describe an unusual case of a 6-year-old Indigenous child who was accidentally shot with a BB gun to the head. He subsequently developed delayed acute right-sided weakness due to symptomatic vasospasm. His symptoms resolved following hypertensive therapy, balloon angioplasty intervention, and intra-arterial milrinone therapy. CONCLUSIONS: This case highlights the unique complication of delayed symptomatic vasospasm in a child following a non-missile intracranial penetrating injury. Intracranial vasospasm needs to be considered in the presence of delayed neurological deficit given its potential reversibility. This case also emphasizes the importance of gun safety and education when handling and storing these potential weapons around children.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
