Abstract
Reversible cerebral vasoconstriction syndrome (RCVS) is typically presented with severe headaches where, vascular imaging demonstrates multiple intracranial arterial narrowing. Variable triggers are related to RCVS, such as serotonin agents and bromocriptine. Thus, a detailed medication history is important. Subarachnoid haemorrhage (SAH) is not uncommon in RCVS. Repeat vascular imaging at 2-3 months with complete reversal of the narrowed vessels confirms the diagnosis of RCVS. The authors present a case where use of triptan along with multiple psychotropic medications, was associated with RVCS. Neuroimaging demonstrated focal SAH and diffuse beaded appearance involving the intracranial vasculature. The patient improved clinically with oral nimodipine treatment. Repeat angiography and a follow-up transcranial Doppler showed complete resolution of vasoconstriction. In the setting of acute severe headache, with any 'red flags', it is important to evaluate the medication use and other precipitating risks for RVCS. Vascular imaging is the key for diagnosis.

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 it
