Cystic endometrial hyperplasia and chronic endometritis in a chinchilla
Bibliographic record
Abstract
CASE DESCRIPTION: A 4-year-old nulliparous sexually intact female chinchilla (Chinchilla lanigera) was evaluated because of a 2-month history of blood being sporadically observed in its cage. CLINICAL FINDINGS: Results of physical examination of the chinchilla were unremarkable except for the presence of blood-stained fur around the perineum. There were no external lesions to account for the bleeding. Findings on urinalysis, bacteriologic culture of urine, and whole-body radiography were unremarkable. The chinchilla's littermate had been evaluated because of similar clinical signs 2 years earlier, and these signs resolved following ovariohysterectomy. TREATMENT AND OUTCOME: Ovariohysterectomy was performed, and gross changes were not observed in the reproductive tract. However, microscopic examination revealed multifocal cystic dilation of the endometrial glands, foci of microhemorrhage, and chronic suppurative inflammation consistent with a final diagnosis of cystic endometrial hyperplasia and chronic endometritis. Clinical signs did not recur. CLINICAL RELEVANCE: Cystic endometrial hyperplasia has been documented in a variety of animals, but to the authors' knowledge, this was the first reported case in a chinchilla. Cystic endometrial hyperplasia and chronic endometritis should be considered as a differential diagnosis in an adult sexually intact female chinchilla with a history of suspected hemorrhagic vaginal discharge, suspected hematuria, or hemorrhage from an unknown source.

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.
