Background
Abdominal wall hernias are a common occurrence that may develop emergent complications. They can also arise, although less commonly, from traumatic injury. It is important to recognize and successfully describe the appropriate findings that will help surgeons provide adequate treatment. Although abdominal hernias can often be identified clinically, imaging can be helpful in cases where the clinical picture doesn’t have a clear diagnosis. It is also useful in localizing the abdominal wall defect and the level of involvement of the abdominal organs.

Educational Goals / Teaching Points
The primary goal of this educational exhibit is to describe abdominal wall hernias with the target audience being medical students, radiology residents, and general radiologists. It includes a brief anatomical review of the abdominal wall musculature and internal organs. A small group of cases provide real-life examples of abdominal wall hernias, with emphasis in the emergency setting and some of them being hernias as a result of traumatic injury. A self-assessment quiz at the end of the presentation helps the viewer consolidate the learning points.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
Various modalities of imaging can be used to visualize abdominal wall hernias. In this exhibit CT is mostly emphasized, due to its ability to produce highly detailed images that will help the radiologist discern the location and contents of the abdominal hernias, as well as characterize abdominal wall defects with high specificity and sensitivity. Other radiologic findings that suggest complications, such as extravasation, can also be appreciated in these images. Imaging aids in identifying other traumatic injuries.

Conclusion
After viewing this exhibit, the reader will have reviewed some basic abdominal anatomy as well as explored the topic of abdominal wall hernias, especially in the emergency setting. They will also be familiarized with traumatic abdominal wall hernias. Though rare, these defects have serious consequences for patients if unnoticed. It should help the student, resident, and general radiologist to identify abdominal wall hernias, their contents, and describe the findings so they can better aid in the emergent management of such cases.
