title: CT findings of pulmonary tuberculosis and tuberculous pleurisy in diabetes mellitus patients.
abstract: OBJECTIVE
  We aimed to assess computed tomography (CT) findings of pulmonary tuberculosis (TB) and TB pleurisy in diabetes mellitus (DM) patients and to evaluate the effect of duration of DM on radiologic findings of pulmonary TB and TB pleurisy.
  
  
  METHODS
  Ninety-three consecutive patients diagnosed as active pulmonary TB with underlying DM were enrolled in our study. As a control group, 100 pulmonary TB patients without DM were randomly selected. TB patients with DM were subdivided into two subgroups depending on diabetes duration of ≥10 years or <10 years. Medical records and CT scans of the patients were retrospectively reviewed and compared.
  
  
  RESULTS
  Bilateral pulmonary involvement (odds ratio [OR]=2.39, P = 0.003), involvement of all lobes (OR=2.79, P = 0.013), and lymph node enlargement (OR=1.98, P = 0.022) were significantly more frequent CT findings among TB patients with DM compared with the controls. There were no statistically significant differences in CT findings of pulmonary TB depending on the duration of DM.
  
  
  CONCLUSIONS
  Bilateral pulmonary involvement, involvement of all lobes, and lymph node enlargement are significantly more common CT findings in TB patients with underlying DM than in patients without DM. Familiarity with the CT findings may be helpful to suggest prompt diagnosis of pulmonary TB in DM patients.
