Which US-hyperechoic benign liver lesion is commonly identified?

Haemangiomas are the most common benign vascular liver lesions and are typically identified on ultrasound as hyperechoic (or brighter) lesions. This hyperechoic appearance results from their high vascularity and the presence of blood within the dilated vascular channels, making them easily distinguishable from other types of liver lesions.

In clinical practice, liver haemangiomas are often found incidentally during imaging for unrelated issues because they rarely cause symptoms or complications. Their characteristic echogenicity, along with their shape and size, helps in making a confident diagnosis, usually without the need for further investigation.

Other options like hepatocellular carcinoma, liver cell adenoma, and cholecystitis do not present with the same consistent hyperechoic properties. Hepatocellular carcinoma, for example, is typically hypoechoic or heterogeneous, and liver cell adenomas can be variable in echogenicity. Cholecystitis, although it can involve the liver due to its anatomical proximity, primarily relates to the gallbladder and would not be correctly classified as a primary liver lesion.
