Oesophageal muscular hypertrophy and pulsion diverticulum in a Friesian horse
Bibliographic record
Abstract
SUMMARY A 13‐year‐old Friesian stallion was referred for evaluation of acute coughing and bilateral nasal discharge. Thoracic radiographs revealed dilation of the terminal portion of the oesophagus, forming a thin‐walled outpouching containing soft tissue opaque material and gas. A diagnosis of oesophageal obstruction with an impacted diverticulum was made. Caudal oesophageal muscularis hypertrophy and an impacted oesophageal diverticulum were found on postmortem examination. Histological abnormalities included a thick caudal oesophageal tunica muscularis and an oesophageal diverticulum composed of mucosa, submucosa and adventitia. Muscular hypertrophy of the oesophagus with diverticulum formation should be considered in Friesian horses presenting with clinical signs of oesophageal obstruction. In this case, thoracic radiographs contributed to a premortem diagnosis, guided medical management and provided information on prognosis. Thoracic radiography can be used as a complementary test in the diagnosis of oesophageal obstruction when endoscopy is available and is a useful diagnostic alternative when endoscopy is not an option.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
