Kaposiform Hemangioendothelioma Presenting Antenatally With a Pericardial Effusion
Bibliographic record
Abstract
We describe an infant presenting with fetal pericardial effusion requiring in utero pericardiocentesis. Important postnatal clinical features included recurrent pericardial effusion, progressive stridor, thrombocytopenia, anemia, and a mediastinal mass surrounding the heart and coronary arteries. Investigations and management consisted of repeat pericardiocentesis, platelet and red blood cell transfusions, laryngoscopy, creation of a pericardial window, and biopsy of the mediastinal mass. Diagnosis was made of Kaposiform hemangioendothelioma surrounding the base of the heart, trachea, and esophagus as well as Kasabach-Merritt phenomenon. The infant responded well to treatment with vincristine and prednisone.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
