A Tracheobronchial Tuberculosis Patient With Diffuse Nodules in the Tracheobronchial Mucosa Observed by Bronchoscopy Misdiagnosed as Lung Infection
Bibliographic record
Abstract
Tracheobronchial tuberculosis (TBTB) is a special form of pulmonary tuberculosis (TB) whose major feature is the infection of the tracheobronchial tree by Mycobacterium tuberculosis . TBTB is diagnosed on histopathological examination of bronchoscopically obtained specimens showing granulomatous inflammation with caseation necrosis and/or positive acid-fast bacilli culture on the microbiological exam. Before bronchoscopy, TBTB is easily misdiagnosed as other lung diseases. This case presentation reports a patient with stable stage pulmonary tuberculosis (PTB) initially misdiagnosed as lung infection before bronchoscopy. Furthermore, sputum smears do not reveal acid-fast bacilli. After being bronchoscopied, the patient showed diffuse nodules in the tracheobronchial mucosa. Sputum culture by rapid liquid method shows positive Mycobacterium tuberculosis . This case can easily be missed diagnosis. It is necessary that bronchoscopy can be a routine means to screen TBTB among the patients with retreated PTB. One rare case was reported. Bronchoscopy showed the presence of diffuse miliary nodules in the mucosa of bilateral bronchi. Pathological examination revealed caseating necrotic granuloma. Mycobacterium tuberculosis was detected by rapid liquid culture. Our case was extremely difficult to diagnose the TBTB without abnormal chest X-ray or computed tomography manifestations. By regular anti-TB treatment with 9 months course, the patient was finally cured with negative Mycobacterium tuberculosis and almost normal tracheobronchial mucosa.

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.
