Spontaneous Spinal Epidural Hematoma in an 11-Month-Old Girl
Bibliographic record
Abstract
An 11-month-old girl was admitted for a 2-month history of regression of motor milestones and lateralizing neurologic findings. Tests for hypercoagulability were all within normal limits except for a moderately elevated fibrinogen level. Urine and blood cultures were negative for growth. Complete MRI of the spine revealed a well-defined extradural inhomogeneous signal intensity extending from C(4) to T(3) suggestive of a subacute hematoma with evidence of evolving hemorrhagic change. There was no evidence of underlying arterial venous fistula or malformation. She underwent a cervicothoracic laminoplasty and evacuation of the hematoma. The clot was confirmed to be a hematoma on pathologic investigation. She made an uneventful recovery with gradual return of neurologic function. This case represents the longest known duration between initial symptoms and definitive management of spontaneous spinal epidural hematoma.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
