Case study of a rare occipital osteoma related to cranial trauma
Bibliographic record
Abstract
century coastal foraging society in California. His remains display a large ectocranial elevation on the occipital, measuring 23.3 mm anteroposteriorly, 25.3 mm mediolaterally, and is elevated to 20.1 mm. It is located along the superior nuchal line on the left side of the occipital and represents an extremely rare occipital localization of a particular type of trauma-related osteoma. In our prior study of Burial 280, trauma etiology was not considered; herein, we present evidence for such a cause. Such trauma-related neoplasms are sometimes called ballooned (or giant, depending on size) osteomas. The presence of this tumor appears to have resulted in asymmetrical cranial muscle use and consequent skeletal changes. This case study illustrates that cranial trauma may sometimes induce benign tumor elevations, rather than a depression or pronounced fracture.

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.
