Background
Air is a common finding on ultrasound examinations, which range from benign to emergent etiologies. Though artifact from air is often seen as a barrier to ultrasound imaging, understanding how to identify and create a diagnostic approach to air on ultrasound examinations is important for making both expected and unexpected diagnoses.
Educational Goals / Teaching Points
This exhibit demonstrates cases of air on ultrasound with detailed descriptions of etiology, methods of detection, and relevant findings. The clinical implications and management for each case are also reviewed to promote successful identification of air on ultrasound and management approaches, which can be urgent or emergent.
Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
This exhibit will highlight the key findings and review the subsequent diagnostic steps in cases of air on ultrasound. The cases include both benign and pathologic cases, with particular attention to critical findings and common pitfalls.
Conclusion
Detection of air on ultrasound and identification of underlying etiology are important for guiding the clinical team toward next steps and management decisions.
