Overview
Ultrasound is the initial method of choice for the evaluation of liver mass. On ultrasound, characteristic findings of liver mass, may include: fluid-filled spaces without clear walls, posterior acoustic enhancement, anechoic, hypohechoic, or hyperechoic lesions. The evaluation of liver mass will mainly depend on the echogenecity. Further evaluation with ultrasound should include Doppler examination to determine vascular pattern.[1][2]
Ultrasound
Ultrasound is the initial method of choice for the evaluation of liver mass. The evaluation of liver mass will mainly depend on echogenecity
- On ultrasound, characteristic findings of liver mass, may include:
- Fuid-filled spaces without clear walls
- Posterior acoustic enhancement
- Anechoic, hypohechoic, or hyperechoic lesions
Types:
- Evaluation with ultrasound should include the following techniques[2]
- Doppler examination
- Contrast-enhanced ultrasound
| Ultrasound | Enhanced ultrasound | |
|---|---|---|
| Benign liver mass |
|
|
| Malignant liver mass |
|

The table below summarizes the characteristic ultrasound findings of common benign and malignant liver masses.
| Ultrasound findings of common liver masses | ||
|---|---|---|
| Common liver masses | Ultrasound finding | |
| Hepatic hemangioma |
| |
| Focal nodular hyperplasia |
| |
| Hepatic adenoma |
| |
| Idiopathic noncirrhotic portal hypertension |
