Abstract
Zenker’s diverticulum is mimicking thyroid nodule on ultrasonograhy (US). Therefore, it has risk of fine needle aspiration (FNA) on that lesion. There are only four case reports in the literature of fine needle aspiration of Zenker’s diverticula masquerading as a thyroid nodule. We report a case of Zenker's dverticulitum suspected to be a thyroid nodule on US and performed US-guided FNA with examination of cytology in this patient. A 53-yr-old woman was referred to our center for FNA of a thyroid nodule. The thyroid US demonstrated a 1.3 × 1.6 cm, poorly-defined nodule containing multiple echogenic foci in the posterior medial aspect of the left thyroid. We performed US-guided FNA on that lesion. Papanicolaou stain showed squamous epithelial cells and numerous bacilli. We diagnosed this patient as having a Zenker’s diverticulum, and this was confirmed by esophagram. doi:10.4021/jmc635e

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 it
