Sonography of Liver Masses
Radiology Video - radiology made esay・2 minutes read
Professor Bill Middleton delivers a lecture on six types of liver lesions, with a focus on the most common, liver cysts, and the importance of sonography in characterizing them and other liver masses in cancer patients. The lecture also covers the various appearances of liver metastases, the need for imaging in detection, and the use of ultrasound-guided liver biopsies for successful diagnosis.
Insights
- Sonography is a valuable tool for detecting and characterizing liver lesions, with a high accuracy rate for identifying cysts, solid metastases, and hemangiomas.
- Liver metastases, common in cancer patients, can present with various sonographic appearances, including target lesions, hypoechoic masses, hyper-echoic tumors, calcified lesions, and cystic metastases, making their detection crucial due to unreliable liver function tests.

Recent questions
What are the common types of liver lesions?
Liver lesions include cysts, hemangiomas, metastases, lymphoma, hepatocellular cancer, and hepatic adenomas.
How can liver cysts be detected?
Liver cysts are typically detected through sonography, displaying anechoic characteristics, posterior acoustic enhancement, and strong reflection from the back wall.
What is the significance of sonography in detecting liver metastases?
Sonography plays a crucial role in detecting liver metastases in cancer patients due to its ability to identify various sonographic appearances of metastatic lesions.
What are the characteristics of hepatocellular cancer?
Hepatocellular cancer is associated with chronic liver diseases, can present as focal, multifocal, or diffusely infiltrating lesions, and often exhibits hyper vascularity detectable by Doppler imaging.
How are hepatic adenomas associated with certain risk factors?
Hepatic adenomas, rare benign liver tumors, are more common in women and linked to factors like birth control pills and anabolic steroids.
