To determine the etiologic orientations lung damage associated with HIV infection in children, we performed a prospective cross-sectional study in 91 patients followed at the Pediatric Hospital Charles de Gaulle to Ouagadougou from 1 January 2012 to 31 July 2013. It consisted in the clinical-radiological analysis of the different lesions observed before pulmonary call signs in children followed for HIV infection. The observed radiological lesions were most often diffuse and bilateral. This was broncho- pneumonia in 87.9% of cases and pleuro-pneumonia in 12.1% of cases. Parenchymal damages were dominated by interstitial opacities alveolar and alveolar-interstitial damages in respectively 29.7%, 24.2% and 12.1% of cases. The etiologies were mostly suspected bacterial pneumonia (62.8%), lymphoid interstitial pneumonia (17.6%), tuberculosis (4.4%) and pneumocystosis (3.3%). Chest radiography accessible to most patients should keep a place in the diagnostic approach. But in many cases it should be complemented with other complementary explorations in order to achieve a specific etiologic diagnosis and improve the treatment of pediatric AIDS.
