A case of cesarean scar ectopic: a rare but important form of ectopic pregnancy
Bibliographic record
Abstract
Abstract Introduction This is a case of a 35-year-old G4P3 female with history of one prior cesarean section who presented to the emergency department with vaginal bleeding. She was found to be pregnant, and an ultrasound identified a cesarean scar ectopic pregnancy. Methods This is a case report and brief review of the literature. Conclusion Cesarean scar ectopic is a rare form of ectopic pregnancy that implants within the myometrium at the site of a prior cesarean section scar. It carries the potential for serious maternal morbidity and mortality, including complications like uterine rupture, life-threatening hemorrhage, and need for hysterectomy. All sonographers who scan patients in first-trimester pregnancy should be aware of the criteria to diagnose this entity, as cesarean scar ectopic can otherwise be confused with cervicoisthmic pregnancy or spontaneous abortion in progress.

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.
