OBJECTIVE: The purpose of this study was to describe the radiographic findings and evolution of round pneumonia found in eight patients with confirmed severe acute respiratory syndrome (SARS). CONCLUSION: SARS may present as round pneumonia on chest radiographs initially or during the treatment course. It may remain unchanged for up to 9 days before evolution to ill-defined air-space opacities. Radiologists and physicians should consider the possibility of "SARS pneumonia" when spherical air-space opacities are noted on chest radiographs of febrile patients.
