Overview
CT is helpful in differentiating the cavitation of abscess that cannot be clearly delineated on the chest radiograph from empyema and other cavitary lesions.[1]
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. [2]
- 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 .[3]
- 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.[4]
