Discordance of Twin Placentas for Multifocal Eosinophilic/T-cell Chorionic Vasculitis
Bibliographic record
Abstract
Eosinophilic/T-cell chorionic vasculitis (ETCV) is an idiopathic placental lesion characterized by chorionic vasculitis composed predominantly of eosinophils and CD3+ T lymphocytes. It usually presents as a unifocal lesion, but a subset have multifocal involvement. We report 4 Di-Di and 2 Di-Mo twins sharing fused placental discs with discordant circulatory involvement by multifocal ETCV. The findings are difficult to explain by sampling alone. The limitation of ETCV to 1 fetus's vascular territory in monozygotic twin pregnancies is difficult to explain but could provide insights into the fetal immune system and the etiology of ETCV.

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.
