: Introduction. Severe pulmonary involvement may occur after adenovirus infection and longstanding pulmonary sequelae may observe essentially bronchiolitis obliterans (BO). Objective. To evaluate the CT findings in children who had suffered adenovirus infection. Patients and method. We reviewed retrospectively the CT findings in 23 children with proven adenovirus infection, excluding those patients with other pulmonary diseases. Results. In all patients CT showed findings consistent with bronchiolitis obliterans, characterized by diffuse or multifocal air trapping with a secondary mosaic attenuation (23 patients), peribronchial thickening and decreased vascularization in the involved areas (23 patients), bronchiectasis (23 patients) and segmental atelectasis (19 patients). In 3 patients the collapsed lobe was resected and histology showed BO. Conclusions. CT was helpful in the study of patients who had suffered adenoviruses infection and showed findings consistent with BO in all of them. This infection could be related with a greater predominance of genome type 7h in South American countries. The amount of pulmonary collapse could be related with the more aggressive serotype of adenovirus in our country
