EP15.27: Rare case of fetal esophageal duplication cyst discovered in pregnancy: a case report
Bibliographic record
Abstract
A 27-year-old healthy primigravida was referred for a fetal multicystic lesion in retrocardiac position measuring 2.6 x 1.6 x 1.3 cm. This lesion was discovered fortuitously upon 36 weeks' ultrasound for gestational diabetes. Fetal growth, amniotic fluid and wellbeing were normal. Anatomic scan was normal at 20 weeks and otherwise normal at time of referral. Fetal echocardiography showed a compressive effect on the left atrium without any outflow obstruction. MRI was performed and described an oval cystic lesion of 3,9 x 1,9 x 2 cm in the mediastina in close contact with the descending aorta, left atrium and pulmonary veins. Differential diagnosis at this time included a cystic lymphangioma and an esophageal cystic duplication. Labour was induced at 39 weeks for gestational diabetes and the patient had a vaginal delivery of a 3,390-kg baby girl with Apgar score of 9-10. The baby was observed in the neonatal intensive care unit for hemodynamic evaluation and was stable without any respiratory support. A cardiac ultrasound done shortly after birth didn't reveal any flow obstruction. The mass was reevaluated by MRI 3 days after birth and the esophageal cystic duplication is now the favored diagnosis with the oblong character and the absence of invasion of adjacent space. The next evaluation by MRI is planed at 2 months of age. This is a rare case of prenatal diagnosis of an esophageal duplication cyst since it is usually diagnosed in infancy. Prenatal diagnosis allowed proper and timely imaging after birth. Please note: The publisher is not responsible for the content or functionality of any supporting information supplied by the authors.

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.
