Abstract:
Objective To explore the relationship between the classification and imageology,the dynamic changes of bronchoscopy and CT features of endobronchial tuberculosis(EBTB).Methods CT findings and bronchoscopic findings in 48 cases with EBTB proved by sputum culture , bronchoscopic biopsy and surgical pathology were analyzed.The classification,dynamic changes and CT characteristics were also evaluated.Results Bronchoscopic results showed 13 of edematous-hyperemic type, 8 of caseous nocrosis type, 5 of fibrostenotic type, 2 of tumorous type, 6 of granular type, 7 of ulcerative type and 7 of mixed type. CT manifestations in different types were intersected,including thickened bronchial wall (64.6%) , bronchial stenosis (41.7%) , aerated bronchus sign ( 37.5% ) ,intra-luminal nodules ( 25% ), bronchial structure with obstructive atelectasis ( 37.5% ) and pneumonia (25% ) .The corresponding rate between bronchoscopy and CT was 83.3% in detecting diseases.19 cases were followed-up by bronchoscopy during the initial 1~5 months of treatment,and 12 cases (3 edematous-hyperemic,4 caseation,3 ulcerative,2 mixed type) were resolved or healed without sequelae,6 cases changed into the other type,4 cases changed into the fibrostenotic type, 2 cases remained in a fibrostenotic state in spite of drug therapy.28 cases were followed-up by CT during the initial 1~5 months of treatment, and 20 cases (6 edematous-hyperemic,4 caseation,3 ulcerative, 1 granular,2 fibrostegnotic 1 tumorous,3 mixed type) were improved,6 cases changed into the other type,2 cases turned into the fibrostenotic type, 2 cases did not improve despite antituberculosis chemotherapy.CT correlated well with fibrobronchoscope(88.5%) in predicting the therapeutic outcome of EBTB.Conclusion CT as a non-invasive method has high clinical value in observing the evolution , predicting the complications and evaluating the therapeutic effect of EBTB.
