Cystic Malformation of Lower Female Genital Tract Resulting in Hydrops Fetalis: A Case Report
Bibliographic record
Abstract
Genitourinary tract malformations causing hydrops fetalis are rare. The authors report a case of a female delivered at 32 weeks gestational age following a prenatal diagnosis of an abdominopelvic cystic mass with hydrops fetalis. The neonate was persistently hypoxic with unstable cardiovascular status and survived only 7 days. At autopsy, a cystic malformation replaced the vagina and uterus, associated with lower vaginal atresia and anorectal agenesis. The cyst had interfered with the normal process of Müllerian duct fusion, leading to a longitudinal vaginal septum and bifurcation of endocervix, with absent uterus and fallopian tubes. The urinary bladder was compressed by the cyst, resulting in bilateral hydronephrosis. The cyst impeded the inferior vena caval and umbilical venous circulations and impinged upon the thoracic cavity with resultant pulmonary hypoplasia. This malformation, which might be termed "cystic dysplasia" of the vagina, represents an extreme form of hydrometrocolpos that resulted in hydrops fetalis.

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.
