RESUMO
Pulmonary tuberculosis (PTB) is the most common clinical presentation of tuberculosis. This study was carried out to appraise the radiological features of PTB in adult HIV-positive and HIV-negative pa-tients. The chest radiographs of the patients were evaluated in the tuberculosis, leprosy, and endemic disease (TBL) clinic, Ebonyi State University Teach-ing Hospital (EBSUTH), Abakaliki, south-eastern Nigeria, from April 2004 to June 2006. Of the total of 117 individuals studied, 68 (58.1) were males and 49 (41.8%) females, indicating a male preponderance of 1.4:1. Up to 49.6% of the subjects had PTB/HIV co-infection. The highest prevalence of PTB/HIV co-infection was recorded among males aged 3140 (12.8%), and females aged 2130 (11.1%). The com-monest radiological features observed were cavitory lesions (64.1%), patchy opacities (44.4%), and hilar opacities (38.5%). Bilateral cavitory lesions, patchy opacities and hilar opacities were more prominent than the right-sided or left-sided ones and appeared more frequently among individuals with PTB/HIV co-infection. Perihilar patchy opacities, consolidation and pleural effusion were seen in 19.6%, 6.0%, and 4.3% of all cases, respectively. There was no statisti-cally significant difference in the association between the radiological features and patient category (Ï2 = 17.74, df = 18, p = 0.47). The chest radiography re-mains an important tool in the diagnosis of PTB and will continue to provide essential information for the management and follow-up of patients
