Core Tip

Core tip: Clinically, hepatic neuroendocrine neoplasm (hNEN) is rare, and few reports are currently available on the imaging diagnosis of hNENs. In this study, by comparing hNEN and hepatocellular carcinoma, hNEN from different sources, and differentiation, it was found that the ultrasound characteristics of hNEN are mostly multiple, uniform hyperechoic masses. The enhancement at the arterial phase was mostly uniform and high, and the washout was rapid compared with hepatocellular carcinoma. Compared with hepatic neuroendocrine tumor, the enhancement at the portal venous phase of hepatic neuroendocrine carcinoma was low, and the enhancement form was non-uniform.
