Imaging Features of Normal and Abnormal Lymph Nodes
2013 ACR Management System
TERMINOLOGY
Definitions
- "Incidental" lymph nodes are those discovered in patients who are undergoing imaging for unrelated reasons
- Lymph nodes are commonly visualized on every cross-sectional imaging exam and are overwhelmingly benign, although radiologist must play role in risk stratifying which lymph nodes require further work-up
ACR Recommendations 2013
- Incidental findings committee provided recommendations for management of lymph nodes encountered on imaging exams using clinical history, prior imaging exam data, and imaging findings
- Recommendations based on expert opinion and published evidence
- Goal is to risk stratify and identify those lymph nodes that require further work-up using combination of imaging characteristics, clinical history, patient risk factors, and prior imaging
CLINICAL IMPLICATIONS
