Diagnosis of Focal Liver Masses on Ultrasonography

Abstract

Ultrasonography (US) is a non-invasive, rapid, and simple examination to diagnose liver disease. The diagnosis of liver mass is often encountered on US examination and the differentiation between benign and malignant tumor is very important. We can perform the differential diagnosis of liver mass according to the sign of US. Hyperechoic rim around the edge of liver mass is shown in the hepatic hemangioma. Hypoechoic halo surrounding a tumor suggests probable malignancy, and multiple masses with target sign most often suggest hepatic metastases. A single multilocular cystic tumour with upstream bile duct dilatation or mural nodules is typically seen at the malignant cystic neoplasm. This review summarized the characteristics of US findings between benign and malignant liver mass. Keywords: Ultrasonography; Hepatic neoplasm; Diagnosis 중심 단어: 초음파; ê°„ì¢ ê´´; 진단
