title: Pretreatment and posttreatment radiography in patients with pulmonary tuberculosis with and without human immunodeficiency virus infection.
abstract: OBJECTIVE
  The purpose of this study was to determine differences in pretreatment and posttreatment radiographic findings in pulmonary tuberculosis (PTB) patients with and without human immunodeficiency virus (HIV) infection.
  
  
  METHODS
  All patients were reviewed in terms of pre- and posttreatment radiographic findings comparing non-HIV-related versus HIV-related PTB.
  
  
  RESULTS
  Among 177 PTB patients, 38 (22%) were HIV seropositive and 139 (78%) were HIV-seronegative. The most common radiographic finding in non-HIV-related TB was reticular infiltration (66.2%), whereas the miliary pattern was the most common radiographic finding in HIV-related TB (34.2%). Radiographic findings in HIV related TB significantly presented with higher prevalence of the miliary pattern (P < 0.0001) and lower prevalence of reticular infiltration (P < 0.0001), cavitation (P = 0.003), and mass-like lesions (P = 0.039) compared to non-HIV-related TB. During the posttreatment period, normal chest radiographs were significantly present in the patients who had HIV-seropositivity, the miliary pattern, and sputum negative for acid-fast bacilli during the pretreatment period (P < 0.05).
  
  
  CONCLUSIONS
  Pretreatment radiographic features of HIV-related TB had a significantly higher prevalence of the miliary pattern and lower prevalence of reticular infiltration, cavitation, and mass-like lesions. HIV-related TB and the miliary pattern seen by pretreatment radiography were significantly associated with normal chest radiographs during the posttreatment period.
