CT Scan

• On CT scan lung abscess is visualized as a rounded radiolucent lesion with a thick wall and ill-defined irregular margins, and is located within the parenchyma compared with loculated empyema, which may be difficult to distinguish on chest radiographs.
• Computed tomography (CT) lung is considered as the gold standard not only for the diagnosis of lung abscess but also for guiding therapeutic procedures such as trans-thoracic drainage of localized lung abscess .
• CT scan is very helpful in excluding endobronchial obstruction due to malignancy or foreign body and provides additional information about size and location of the abscess.
