Abstract: Primary hepatic angiosarcoma (PHA) is a rare malignancy with a badly poor prognosis. The extremely low morbidity and untypical clinical manifestations conduce to a missed diagnosis. The present study reported a case of an adult male patient who was pathologically confirmed to be PHA, which mimicked intrahepatic cholangiocarcinoma on conventional ultrasound and contrast-enhanced ultrasound. Findings on various imaging examinations were carefully evaluated and the associated literatures were also reviewed.
