Mediastinal Abscess Following Endobronchial Ultrasound Transbronchial Needle Aspiration in a Patient With Sarcoidosis
Bibliographic record
Abstract
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive procedure with a low rate of complications. It is used in the diagnosis of malignant and benign disease such as sarcoidosis. We report a case a 42-year-old man who had undergone EBUS-TBNA for diagnosis of mediastinal and hilar lymph node enlargement. Sarcoidosis was diagnosed on cytologic examination. Three weeks after the procedure, he developed a mediastinal abscess secondary to EBUS-TBNA. Sarcoidosis may be a risk factor for mediastinal infection complication. A local immune defect related to sarcoidosis may explain this risk. Our case underlines the importance of considering and recognizing this complication, and its possibility should be taken into account when undertaking the procedure for benign disease.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
