A diverse, multi-system spectrum of pathologies can be diagnosed or suspected by identifying abnormal air and its location on chest radiographs. The goal of this presentation is to expose the learner to many of the different manifestations of abnormal air seen on chest radiography to improve the learner’s diagnostic ability. The importance of maintaining a rigorous, systematic search pattern will also be reinforced, both by providing the search pattern followed by the authors and through the categorization of the diagnoses discussed.

a. Introduction to topic/goals. b. Reinforcement of search pattern with brief demonstration. c. Cases- majority of the presentation will follow a quiz-based format where the learner will be prompted with a question that is followed by the answer, the radiographic findings, and a teaching point. Correlation with advanced imaging, as indicated, will accompany the answer. Case examples will be categorized by location and will include, but are not restricted to: Mediastinum (pneumomediastinum, pneumopericardium, esophageal diverticulum), Lungs (pneumothorax, Macklin effect, empyema), Abdomen (portal venous gas, pneumoperitoneum, intramural gastric air, retroperitoneal air), MSK (vacuum phenomenon, paraspinal abscess), and Soft Tissues (subcutaneous emphysema, sternal dehiscence).
