Retropharyngeal Hematoma Secondary to Vomiting in a Healthy Adult: A Case Report
Bibliographic record
Abstract
Nontraumatic spontaneous retropharyngeal hematoma is rarely encountered. Clinical diagnosis of retropharyngeal hematoma can be difficult and may be infrequently misdiagnosed with acute pharyngitis. A careful history taking is also an important process to diagnose this disease entity. Because of its rarity and difficulty of early diagnosis, retropharyngeal hematoma may rapidly progress to airway compromise. A 51-year-old woman suddenly developed neck pain and dyspnea after vomiting. Examination showed anterior bulging of the posterior oropharyngeal wall without ecchymosis around neck. No underlying medical conditions, medications, or trauma were found. Cervical magnetic resonance imaging revealed retropharyngeal hematoma collection from nasopharynx to laryngopharynx. We report a case of spontaneous retropharyngeal hematoma with increased intrathoracic pressure caused by vomiting. J Med Cases. 2015;6(2):81-83 doi: http://dx.doi.org/10.14740/jmc2038w

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.
