Overview
CT
On Computed tomographic scan, empyema is seen as a lung mass whose cavity is regular with smooth and regular lumen and well-defined boundary. The shape changes with change in patient's position.[1] Mass on CT scan may resolve on antibiotics. The split pleura sign on CT scan is present (most reliable sign to differentiate empyema from lung abscess where it is absent).[2]
