Eight Cases of Severe Acute Respiratory Syndrome Presenting as Round Pneumonia

Abstract

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.
