Incidental Liver Findings on Cross-sectional Imaging

Area of Science:

• Radiology
• Hepatology
• Medical Imaging

Background:

• Incidental hepatic findings are frequently detected during imaging of non-liver areas.
• Radiologists must effectively triage these findings for appropriate further evaluation.
• Distinguishing benign from potentially malignant lesions is crucial.

Purpose of the Study:

• To review common benign hepatic entities seen on various imaging modalities.
• To outline imaging features indicative of malignancy or requiring further investigation.
• To propose algorithms for guiding radiologist recommendations on incidental liver findings.

Main Methods:

• Review of common benign hepatic lesions across ultrasound, CT, and MRI.
• Analysis of imaging characteristics differentiating benign from suspicious findings.
• Development of two decision-making algorithms based on patient risk, lesion size, and imaging features.

Main Results:

• Common benign hepatic entities and their characteristic imaging features are presented.
• Imaging findings suspicious for malignancy are identified.
• Two algorithms are proposed to aid in the management of incidental hepatic abnormalities.

Conclusions:

• Effective triage of incidental liver findings is essential for patient care.
• Characteristic imaging features aid in differentiating benign from malignant hepatic lesions.
• Proposed algorithms assist radiologists in making informed recommendations for further evaluation.
