Giant cell arteritis or tension-type headache?: A differential diagnostic dilemma
Bibliographic record
Abstract
Giant cell arteritis (GCA) or Temporal arteritis (TA) is an autoimmune disease and the most common type of vasculitis in the elderly. It causes inflammation of the medium and large arteries in the upper part of the body. GCA is an under-recognized cause of head aches in the elderly, especially when it presents itself with atypical features, resulting in delayed or incorrect diagnosis. Since GCA is a treatable condition, an accurate diagnosis is crucial to prevent the most serious complication of CGA, permanent vision loss. The diagnosis can be further complicated as GCA may present with features of other painful neurological conditions. The present case is an 81-year-old woman diagnosed with GCA, who initially presented with features similar to tension-type headache. Due to overlapping features of these conditions, the diagnosis of GCA was delayed, resulting in irreversible vision loss. Although previous research highlights diagnostic dilemmas featuring GCA and other disease states, this case is exclusive in describing a unique dilemma where tension-type headache mimics GCA.

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.
