Abstract
A 67-year-old male presented with shortness of breath, irregular heart rhythm, and swollen legs, which had started 4 months previously. He had a previous history of simultaneous quadruple aortocoronary bypass and Ravitch-type repair of the pectus excavatum (Figure 1A) 6 years previously, with successful postoperative course. An electrocardiogram showed atrial fibrillation. Chest pain was absent, and all vein grafts were intact on coronary angiography. Chest computed tomography showed a partially calcified mediastinal mass measuring 6 cm in size (Figure 1B), compressing the right ventricle (Video 1) and right pleural effusion. A transthoracic echocardiogram showed that cavity size and systolic function of the right ventricle were reduced by the mass and also that the inferior vena cava was dilated consistent with increased right atrial pressure. Left ventricular systolic function was preserved. We excised the mass, which had a hard shell (Figure 1C), and performed intraoperative electrical cardioversion. Rhythm was successfully reverted, and the postoperative course was uneventful. The patient was asymptomatic with regular pulse 3 months after surgery. Histological examination indicated chronic hematoma. This late presentation may represent a chronic expanding hematoma (1). Most cases of chronic chest hematoma have been reported in the context of trauma (2) or surgery for tuberculosis (3, 4).

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
