Mystery Case: Migraine, hearing loss, and blurred vision in a young woman
Bibliographic record
Abstract
A 39-year-old previously healthy woman presented with a 3-week history of progressive frontal headaches that were of pulsatile quality, moderate severity, and associated with occasional photophobia and nausea.She denied a history of headaches and managed her pain without medication.She reported generalized malaise and perioral and bilateral hand paresthesia.At the time of assessment, she also endorsed diminished hearing and tinnitus in her left ear and intermittent blurry vision in both eyes.On physical examination, the patient was apathetic and in no apparent distress.She denied subjective cognitive deficits, but her Montreal Cognitive Assessment (MoCA) 7.1 score was 26/ 30 (producing only 8 F-words on verbal fluency, impaired abstraction, and missing a word on delayed recall).On cranial nerve inspection, her visual acuity was 20/20 in both eyes and confrontation visual fields were full.Pupils were of equal sizes, with no relative afferent pupillary defect on either side.Dilated fundus examination revealed 1 cotton-wool spot in the right eye and 2 cotton-wool spots in the left eye, with sheathing of a nasal retinal arteriole in the right eye (figure ,A).Extraocular eye movements were full, with normal saccades and smooth pursuit.There was no appreciable auditory loss on bedside testing, and the remainder of the cranial nerves were intact.Motor examination revealed normal muscle bulk and tone, power 5/5, and reflexes 2+ with normal plantar responses.Sensory examination was intact to pinprick and vibration.Cerebellar examination revealed no dysmetria and normal rapid alternating movements.Gait was intact. Questions for consideration:1. What further investigations might assist in making the diagnosis?2. What features would you expect to see on brain MRI? 3. What are the differential diagnoses to consider?

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.
