Resolution of Spontaneous Spinal Epidural Hematoma Without Surgery
Bibliographic record
Abstract
STUDY DESIGN: Case report. OBJECTIVE: To report two cases of spontaneous spinal epidural hematoma that completely resolved, clinically and radiographically, without surgical treatment. SUMMARY OF BACKGROUND DATA: The treatment of spinal epidural hematoma is usually surgical. Spontaneous spinal epidural hematoma is an uncommon phenomenon and may be of uncertain cause. METHODS: One patient with acute onset of complete quadriplegia and another with complete paraplegia caused by spontaneous spinal epidural hematoma were treated without surgery. RESULTS: Both patients recovered nearly completely with respect to their neurologic function at 3-month follow-up. No source of hematoma was ever identified. CONCLUSIONS: Spontaneous spinal epidural hematoma should be considered in the differential diagnosis of sudden onset of spinal cord compression in association with back pain. Patients initially presenting with severe neurologic dysfunction are potential candidates for conservative management if they demonstrate rapid and progressive improvement in neurologic function. Patients treated in this manner can have nearly complete restoration of function.

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.
