P05.02: The congenital dorsal dermal sinus—antenatal detection with 2D/3D ultrasound and postnatal evaluation with MRI and CT
Bibliographic record
Abstract
Congenital dorsal dermal sinuses (CDDS) are posterior, midline, congenital malformations of the spine. They are a form of occult spinal dysraphism characterized by thin, epithelium-lined channels that open on the skin posteriorly as a variety of cutaneous lesions. We describe four cases in which the CDDS tract was detected antenatally in 3 cases with 2D and 3D ultrasound and its presence was suspected in one case of lumbar spinal dysraphism. All cases were evaluated postnatally with MRI, while postnatal CT was performed in selected cases to evaluate the severity and extent of the spinal dysraphism. Discussion on antenatal ultrasound diagnosis, the value of 3D ultrasound for assessing both the sinus tract and bony spinal dysraphism are discussed and correlated with antenatal MRI and postnatal imaging.

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.
