[Spiral CT evaluation in diagnosis of endobronchial tuberculosis].

OBJECTIVE
To determine the value of spiral CT in diagnosis of endobronchial tuberculosis (EBTB) after analysing the spiral CT appearance.


METHODS
Retrospective analysis of CT signs in 13 cases who were finally pathologically found suffering from EBTB via biopsy with bronchoscope.


RESULTS
Five cases have signs of bronchial structure with obstructive atelectasis and pneumonia. Two cases have signs of irregular bronchial wall. Four cases have signs of scattering dot and patchy increase density in lung fields. Two cases' bronchi and lung tissues are normal.


CONCLUSION
CT examination can determine the site and extent of EBTB and help the localization of bronchoscope.
