Intra-arterial milrinone may differentiate fulminant RCVS from vasculitis
Bibliographic record
Abstract
A 39-year-old woman taking a monoamine oxidase inhibitor presented with a 1-week history of severe non-thunderclap headache and visual field deficits. Brain CT showed infarcts in both parietal lobes, with narrowing of intracranial vessels on CT angiogram (figure 1), suggesting either vasculitis or reversible cerebral vasoconstriction syndrome (RCVS). Despite treatment with both methylprednisolone and nimodipine, she experienced progressive aphasia and right leg weakness. She underwent an urgent cerebral angiogram (figure 2), during which intra-arterial milrinone reversed both the vasoconstriction and its symptoms, thereby confirming RCVS. Intra-arterial milrinone may be useful to differentiate vasculitis from RCVS1 and may serve as a treatment for RCVS, but requires prospective evaluation.

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.
