Prenatal Diagnosis of a Large Subchorionic Placental Cyst with Intracystic Hematomas
Bibliographic record
Abstract
A large intrauterine cyst containing a heterogenous mass was found by ultrasound in the placenta of a 35-year-old gravida 2 para 1 woman. The cyst, measuring 10.9 x 10.1 cm with a heterogenous mass shadow, was attached near the placental cord insertion site. The woman delivered a healthy female baby weighing 3,330 g by cesarean section without complication. A histopathological examination revealed that the lesion was a subchorionic cyst and contained an internal hematoma. Large subchorionic cysts are extremely rare, and secondary hemorrhage within the cyst has not been reported. In this article, we report the case of a woman with a large subchorionic cyst complicated by an intracystic hematoma and review its clinical significance.

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.
