Abstract
Fibromatosis colli is a rare, benign mass of the sternocleidomastoid muscle (SCM), typically diagnosed in infants between weeks 1 to 8 of life. Physical examination of the infant will exhibit a firm lump on the affected side of the neck. The mass is typically unilateral and may be accompanied by torticollis. We present two cases of infants with fibromatosis colli. Sonographic examination is the preferred initial non-invasive diagnostic procedure, with 100% sensitivity. Ultrasound can confirm the diagnosis, avoiding unnecessary invasive interventions. Early diagnosis can prevent complications such as plagiocephaly, facial asymmetry, and scoliosis. We aim to provide the tools necessary to recognize fibromatosis colli by describing three key sonographic appearances. We will present two separate cases that demonstrate these findings and discuss how to sonographically rule out the many differential diagnoses.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
