ABSTRACT
BACKGROUND: Endobronchial tuberculosis (EBTB) is a challenging diagnosis because of its varied clinical and radiological manifestations. Hilar asymmetry on chest radiograph (CXR) may be found in patient with EBTB but is often overlooked, which may lead to delayed diagnosis. CASE REPORT: We present five cases with EBTB. Clinicians failed to identify unilateral hilar abnormalities on CXR, and these patients were treated initially for pharyngitis, bronchitis, or pneumonia with no improvement. Subsequently, they visited the pulmonary clinic and bronchoscopy revealed endobronchial lesions and microbial/histopathological evidence of tuberculous infection consistent with EBTB. Anti-tuberculosis therapy resulted in complete clinical resolution in four of the five patients; one patient had persistent bronchial stenosis. CONCLUSION: Hilar asymmetry on CXR may occur with EBTB and may suggest this diagnosis in the appropriate clinical setting. Bronchoscopy has an important role in establishing the final diagnosis.
