Diagnosis With Brief Discussion
- Diagnosis
- Endobronchial tuberculosis
- Radiologic Findings

Fig 2. CT scan reveals diffuse bronchial wall thickening in the right bronchus with RUL atelectasis.

The patient underwent sputum lab and bronchoscopy and was diagnosed with endobronchial TB.
- Brief Review
- Bronchial stenosis occurs in 10%–40% of patients with active tuberculosis and is due to direct extension from tuberculous lymphadenitis by means of endobronchial or lymphatic dissemination. The main radiographic features of proximal airway involvement are indirect, including segmental or lobar atelectasis, lobar hyperinflation, mucoid impaction, and postobstructive pneumonia. At CT, airway involvement can manifest as long segment narrowing with irregular wall thickening, luminal obstruction, and extrinsic compression.
