Huge Extrapleural Hematoma Initially Diagnosed as Massive Hemothorax
Bibliographic record
Abstract
We report a 50-year-old man who presented with left chest pain after blunt thoracic trauma. A chest radiograph showed a fracture of the left 4th rib. Three days later, worsening chest pain and shortness of breath occurred. A repeated chest X-ray showed a complete opacity of the left hemithorax. The patient was reported to have a massive left hemothorax leading to a shift of the mediastinum to the right. Tube thoracostomy was performed immediately. However, only a small amount of blood-like fluid was drained and the left hemithorax still appeared as a near total opacity on the follow-up chest radiograph. These findings were interpreted as a massive clotted hemothorax. Surprisingly, an emergency video-assisted thoracic surgery (VATS) revealed no traumatic pleural collections but a huge pleural mass containing a large amount of dark, reddish blood clots. The blood clots were evacuated. No bleeding source was found. The patient made a good recovery and was discharged on the 3rd postoperative day.

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.
