Left pleural empyema

Axial computed tomography (CT) scan of the chest (A) and coronal reformat (B) in a patient with left pleural empyema caused by Group A Streptococcus. CT scans show several left apico-lateral and left medial, paracardiac loculations of pleural effusion with internal septations with contrast-enhancing pleural and adjacent compressed lung (dashed arrow). An accompanying unrelated right transudative pleural effusion is also present: an example of Contarini's condition. Arrows in the coronal reformat shows a liver abscess.
