Abstract
Introduction Tuberculosis remains a major cause of death worldwide despite a decline in incidence in recent years (1). It is estimated that there were 9.6 million new cases of tuberculosis [...]
Asymptomatic pulmonary tuberculosis (PTB) mimicking lung cancer is rare and has been documented in few studies. Accurately diagnosing this atypical disease remains an enormous challenge for clinicians. The aim of the present study was to characterize asymptomatic patients with PTB who were initially diagnosed with lung cancer according to their chest computer tomography (CT) or whole-body [sup.18]F-fludeoxyglucose-positron emission tomography-computer tomography (PET-CT) presentations. The clinical characteristics and radiographic features of patients with PTB were analyzed and compared to those of patients with lung cancer. In patients with PTB, all lesions exhibited suspected malignant signs on chest CT and the maximum standard uptake value ([SUV.sub.max]) of PET-CT imaging was between 2.65 and 10.9. Compared with lung cancer, the factors associated with PTB included an age Key words: pulmonary tuberculosis, lung cancer, computed tomography, positron emission tomography, clinical characteristics, early diagnosis
