In lung ultrasound, a chest wall abscess (US) appears as a localized collection of pus within the soft tissues of the chest wall. This condition, often resulting from infection, trauma, or postsurgical complications, typically presents as a hypoechoic or anechoic mass with irregular borders, potentially containing internal echoes or septations. The presence of fluid-fluid levels, gas, or debris within the collection further supports the diagnosis, and Doppler imaging may reveal peripheral vascularity.
Diagnosing a chest wall abscess via ultrasound is crucial in medical practice for guiding drainage procedures and monitoring treatment response. Its proximity to the lung necessitates careful differentiation from pleural effusions or lung consolidation, which can present similarly. Ultrasound offers a non-invasive and real-time method for accurate assessment and management of these infections.
