An unusual presentation of a branchial cleft cyst in a 70-year-old
Bibliographic record
Abstract
Branchial cleft cysts are common congenital head and neck masses predominantly presenting in a pediatric setting. Most branchial cleft cysts do not provide a diagnostic challenge as they have consistent physical locations and clinical presentation. This paper describes a rare case of branchial cleft cyst isolated in the parapharyngeal space. To our knowledge, this is the oldest presentation of a parapharyngeal space branchial cleft cyst in the literature. A 70-year-old non-smoking gentleman presented with a subacute presentation of dysphagia and odynophagia. Physical examination revealed a right posterior oropharyngeal swelling. On imaging he was found to have a 4.6cm cystic, right parapharyngeal mass abutting the prevertebral fascia. Fine needle aspirate suggested benign pathology. Surgical resection was pursued and final pathology was consistent with a branchial cleft cyst. Benign congenital branchial cleft cysts should be considered in the differential diagnosis for parapharyngeal masses, regardless of age.

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.
