Sudden Death of a Young Man by Acute Hemorrhagic Leukoencephalitis
Bibliographic record
Abstract
We report a case of acute hemorrhagic leukoencephalitis in an adult man with a prodrome of "feeling unwell" two days prior to this death. At autopsy, external examination revealed minor external injuries including contusions on the scalp and left thigh and abrasions on the forehead and right eyebrow. Gross examination of the brain after coronal sectioning revealed multiple petechial hemorrhages in the white matter in the cerebral hemispheres, corpus callosum, basal ganglia, brainstem, and cerebellum. Microscopic examination of these lesions revealed demyelination, hemorrhage, and necrosis with fibrin exudation in a perivenular distribution with radial extension into the white matter. The remainder of the autopsy was unremarkable. This case highlights the death of a young man by a rare fatal complication of a natural disease only identified by a singular set of gross and microscopic findings at autopsy in circumstances that would otherwise suggest a nonnatural death. The case demonstrates the importance of a thorough autopsy in settings where the clinical history, scene, and circumstances may be misleading or absent.

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.
