Acute Retropharyngeal Calcific Tendinitis or Calcium Hydroxyapatite Deposits in Longus Colli Muscle
Bibliographic record
Abstract
Acute retropharyngeal calcific tendinitis, also called calcium hydroxylapatite deposition disease, is a little known entity that causes pain and neck stiffness associated with odynophagia. Radiographically, it manifested with calcium deposits and an edematization of retropharyngeal soft tissues. Retropharyngeal impacting typically occurs to the long neck muscle tendon insertion or longus colli, although it is rarely described, in the literature. We present a clinical case treated in the Department of Traumatology and Orthopaedic Surgery of Hospital Clinico Universitario of Santiago de Compostela (La Coruna, Spain), discussing the clinical-radiological characteristics and treatment according to the little existing literature on the subject. After the analysis of the data obtained from the review of this case, we can conclude that the most important element for the diagnosis of this entity is the knowledge of its existence and recognition of its characteristics in plain X-ray and CT. It is self-limited and her treatment consists of anti-inflammatory agents, non-steroidal and neck brace immobilization. J Med Cases. 2017;8(2):63-66 doi: https://doi.org/10.14740/jmc1650w

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.
