Purulent Pericarditis Following Endobronchial Biopsy of Lymph Node (4R)
Bibliographic record
Abstract
BACKGROUND: Purulent pericarditis is a rare but life-threatening complication of endobronchial ultrasound-guided fine-needle aspiration (EBUS-FNA) of intrathoracic lesions. CASE SUMMARY: A 65-year-old man with hypertension and hearing loss presented with an aggressive case of purulent pericarditis leading to cardiac tamponade post-EBUS-FNA of a station 4R lymph node. Transthoracic echocardiogram demonstrated fibrinous stranding and tamponade physiology. Pericardiocentesis drained over 500 mL of purulent fluid positive for Streptococcus mitis. The patient was successfully managed with a prolonged course of culture-guided intravenous antibiotics. DISCUSSION: To our knowledge, this is the first reported case of S. mitis purulent pericarditis post-EBUS-FNA. TAKE-HOME MESSAGE: This case highlights the differential diagnosis of chest pain in patients undergoing EBUS-FNA and the utility of transthoracic echocardiography in the diagnosis of effusion-constrictive pericarditis.

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.
