Fibrous Dysplasia of the Skull Base Presenting Acutely in an Adult
Bibliographic record
Abstract
Fibrous dysplasia (FD) of the bone is an idiopathic disorder in which bone-forming mesenchyme develops abnormally. Here, we describe an unusual case in an adult, with recurrent acute headache and third nerve palsy due to FD of the skull base and low-grade fibrosarcoma. A previously healthy 32-year-old female office clerk, presented with an eight day history of acute-onset, severe, right occipital and retro-orbital continuous headache, associated with nausea and vomiting. She had required dimenhydrinate, acetaminophen with 15 mg codeine, and meperidine with only mild relief of the headache. She also described a 5-day history of right eye ptosis which had progressed to eye closure by the time of presentation. She had otherwise been well, with no systemic or constitutional symptoms and no previous history of headaches.

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.
