Summary
Radiologists often find unexpected liver lesions during screening CT scans and ultrasounds. Many of these focal and diffuse liver diseases are benign and can be identified using imaging techniques like ultrasound, CT, and MRI.
Area of Science:
- Radiology
- Medical Imaging
- Hepatology
Background:
- Screening CT scans and ultrasounds are frequently performed in clinical practice.
- Incidental liver findings are common in radiologic practices.
- Distinguishing benign from malignant liver lesions is crucial.
Purpose of the Study:
- To review the spectrum of benign focal and diffuse liver diseases.
- To highlight imaging characteristics of these benign conditions on ultrasound, CT, and MRI.
- To aid radiologists in the interpretation of incidental liver findings.
Main Methods:
- Review of common benign focal liver lesions.
- Review of common benign diffuse liver diseases.
- Discussion of imaging appearances on ultrasound, computed tomography (CT), and magnetic resonance (MR) imaging.
Main Results:
- Benign focal liver lesions include cysts, hemangiomas, and focal nodular hyperplasia.
- Benign diffuse liver diseases include steatosis and cirrhosis.
- Ultrasound, CT, and MR imaging allow for confident characterization of many benign liver processes.
Conclusions:
- A significant proportion of incidental liver lesions discovered on screening imaging are benign.
- Familiarity with imaging features of benign liver diseases is essential for accurate diagnosis.
- Appropriate use of ultrasound, CT, and MR can help avoid unnecessary invasive procedures.
