Rare lymphatic malformation in an extreme premature infant: question
Bibliographic record
Abstract
Our patient was born to a healthy 35-year-old Asian mother. The pregnancy was uneventful until 25 weeks of gestational age (GA), when she had preterm prolonged rupture of membranes (PPROM). Ultrasound at that point showed a new finding (confirmed by MRI) of 4.7 x 4.1 cm heterogenous cystic skin-covered mass with areas of echogenicity on the posterior aspect of the fetus with blood flow to the mass and minimal vascularity overall. The male infant was delivered at 26 + 4 weeks by emergency caesarian section for fetal distress with birth weight of 720 grams. A significant finding was a massive swelling over the upper back with a firm central mass. Total size of swelling was 10.2 x 12.2 cm, central cystic mass was smaller (5.0 x 4.2 cm), firm in consistency, slightly mobile, non-pulsatile, non-compressible and non-translucent. Examination of mass did not cause changes in vital signs, thus the mass was considered as a painless malformation. • What is your diagnosis? • Which further investigations would you suggest? • Which subspecialties need to be involved in the management of this case?

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.
