Abstract: Objective To study the clinical features,bronchoscopy manifestations,CT manifestation,and prognosis of active caseation endobronchial tuberculosis(EBTB). Methods Clinical symptoms,chest X-ray/CT manifestations and fiberoptic bronchoscopic findings of 72 cases diagnosed with EBTB were analyzed retrospectively. Results Main features were as followed: stimulating cough,non-specific fever,increased risk of lung infection,high sputum positivity,increased erythrocyte sedimentation rate(ESR) and C-reactive protein(CRP).CT is less effective than bronchoscopy to diagnose this type of EBTB.Active treatment could yield a positive result. Conclusion Active caseation endobronchial tuberculosis EBTB has specific clinical features.Bronchoscopy is the key method for detection.Active treatment may improve the outcome,however,difficulties are still existing in treating active caseation endobronchial tuberculosis.
