Cerebral Sinovenous Thrombosis Masquerading as Migraine
Bibliographic record
Abstract
Headaches are common during childhood and a common pediatric presentation to emergency departments (EDs). The most common diagnoses for acute headache in the pediatric ED are viral upper respiratory tract infection with fever, sinusitis, and migraine, accounting for 70% to 75% of presentations; serious neurologic diagnoses are rare. Most literature recommends against neuroimaging for uncomplicated headache given the absence of any other signs or symptoms associated with causes of intracranial pathology and the presence of a normal physical examination. Cerebral sinovenous thrombosis (CSVT) is a rare entity whose diagnosis relies heavily on neuroimaging and which carries high morbidity and mortality if untreated. Pediatric CSVT has yet to be presented in the emergency medicine literature. We report the case of a child who presented to the pediatric ED with headache, which was complicated by background difficulties with aggression and other behavioral issues. This case illustrates an extremely rare ED presentation of CSVT masquerading as migraine headache and discusses the diagnostic dilemma of neuroimaging.

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.
