Spontaneous Rupture of Fetal Sacrococcygeal Teratoma
Bibliographic record
Abstract
With recent advances in technology, fetal sacrococcygeal teratoma is being diagnosed increasingly during the early prenatal period by ultrasound examination. In addition, early detection of tumor related complications such as polyhydramnios, congestive heart failure, hydrops, hemorrhage, urinary tract or bowel obstruction can be followed closely in utero. Active prenatal management can improve fetal perinatal outcome by allowing planned delivery for neonatal surgery [Chisholm, C.A. et al.: Am J Perinatol 1999;16:47-50] or in some cases, fetal intervention. Additionally, families can be counseled appropriately regarding the range of outcomes. We report a case of fetal sacrococcygeal teratoma Type I diagnosed at 20 weeks with a prominent vessel supplying the tumor mass. At 23 weeks, there was a sudden appearance of an additional lobular mass, consistent with intrauterine spontaneous ruptured of a sacrococcygeal teratoma mass.

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.
