Abstract: Radioactive 125I seed implantation has definite curative effect in the treatment of local liver cancer. Currently, percutaneous implantation guided by CT, nuclear magnetism or ultrasound can be adopted, which is safe and minimally invasive. However, the images of some patients with metastatic liver cancer show isodensity or iso-echo imaging under CT or ultrasound, which is easy to miss diagnosis and treatment, seriously affecting the quality of life of patients. A case of terminal cholangiocarcinoma of the biliary tract with metastasis to the liver was admitted to China-Japan Union Hospital of Jilin University. Ultrasound image showed iso-echo, and radio 125I seed implantation was performed under the guidance of contrast-enhanced ultrasound. The operation was completed according to the preoperative treatment plan.
