RETURN TO ABSTRACT LISTING


Background
In the field of radiology, approximately 10% of practitioners specialize in abdominal radiology, and abdominal CT scans account for more than 40% of total CT scans in adult patients. These abdominal CT scans provide invaluable information about areas surrounding the abdominopelvic cavity and often reveal incidental findings in these areas. Notably, 28% of CT scans of the abdomen report incidental findings, many of which are nonabdominal. For instance, 3% of abdominal CT scans reveal incidental lung nodules, and 6% unveil bone findings. The management and follow up of these nonabdominal findings pose challenges for subspecialized abdominal radiologists.

Educational Goals / Teaching Points
Our objective is to review common nonabdominal incidental findings discovered on abdominal CT scans. We will provide abdominal radiologists with a systemic framework for selecting appropriate management strategies and follow-up plans.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
We will present a systemic approach to managing key nonabdominal incidental findings, including cardiac, pulmonary, bone, spinal, and soft tissue findings including Aunt Minnies. Examples include pulmonary nodules, coronary artery calcifications, abdominal wall lesions, and solitary and multifocal bone lesions.

Conclusion
Although radiology trends toward subspecialization, abdominal radiologists are likely to encounter nonabdominal incidental findings in their daily flow. Having a systematic approach will help in the identification and delivery of recommended follow-up.
