Between June 2009 and August 2010, the World Health Organization (WHO) declared a pandemic of the influenza H1N1 virus. Until June 2010, there were 3,572 confirmed cases of influenza AH1N1 virus respiratory infection in Colombia, with 239 deaths. Objectives: To describe the radiological studies of a group of 38 patients with a confirmed influenza A(H1N1) respiratory infection diagnosis who required hospitalization. The radiology results were correlated with clinical symptoms. Methodology: Medical records and image studies retrospective analysis of a 38 patient cohort with confirmed influenza A H1N1 infection diagnosis, who were hospitalized at the Universitario Mayor - Méderi Hospital in Bogota, Colombia between June 2009 and March 2010. Patients were divided into two groups according to the need for ventilatory support during hospitalization. The image studies were reviewed by two radiologists with thoracic radiology experience. Results: Radiographs, the findings were consolidation and ground glass images. In the group requiring mechanical ventilation, all radiographs were abnormal. Conclusions: In our series, the image study findings were correlated with the severity of the clinical symptoms. Among the patients requiring mechanical ventilation, the thoracic lation had radiological alterations at admission. The most common radiographic finding in the group of patients who required mechanical ventilation was basal parenchymal consolidation.
