Background
The presence of air in numerous locations (pleural space, peritoneum, parenchyma of various organs) is a cause for concern in the emergency setting. However, numerous benign conditions can result in air in unusual locations. It is important for the practicing radiologist to be aware of these pitfalls to avoid unnecessary alarm and to prevent additional unneeded imaging or procedures. The purpose of this presentation is to demonstrate numerous cases where air can present in unusual locations, which are associated with benign etiologies. Through this educational activity, we aim to help trainees and practicing radiologists alike to distinguish benign from pathologic entities of ectopic air.
